Proposed amendments to CITES appendices

2009-12-12T06:57:00.004+08:00

In March 2010 CITES (What is CITES? ) Parties will meet to discuss the potential inclusion of the marine species to the convention appendices list:

Lamna nasus - Porbeagle
Sphyrna lewini - Scalloped hammerhead
Sphyrna mokarran - Great hammerhead
Sphyrna zygaena - Smooth hammerhead
Carcharhinus plumbeus - Sandbar shark
Carcharhinus obscurus - Dusky shark
Carcharhinus longimanus - Oceanic whitetip
Squalus acanthias - Spiny dogfish
Northern Bluefin tuna - Thunnus thynnus

The shark species are all threatened by overfishing for sharks fin soup, for meat consumption and as a result of fishing bycatch. The bluefin tuna is overexploited to feed the worldwide sushi craze..

We hope that these inclusions are accepted and measures implemented as soon as possible. Inclusion of additional shark species (only the whale shark and basking sharks are currently protected) is important, the bluefin tuna is on the verge of complete collapse and efforts to protect this wonderful animal are too little but hopefully not too late.

There are often strong political resistence to expanding the list of protected animals.

Bluefin consumption in Hong Kong

2009-07-26T20:10:00.004+08:00

WWF in Hong Kong has successfully managed to get some high profile restaurants to ban the sale of bluefin tuna in their outlets. Too little for now, but a start...

Lessons from the visit to Hong Kong of a humpback whale

2009-05-17T08:14:00.003+08:00

The visit in early/mid March of a humpback whale in Hong Kong was an amazing and unexpected event, and provoked a lot of interest with the Hong Kong public.

To the credit of the Hong Kong authorities (AFCD) when it became clear that the whale was showing signs of distress from this attention, they quickly implemented measures to ensure that disturbance to the animal was minimised. These steps were successful and the good news is that the whale has not been seen since the 26th March, presumably finding his way back to his normal migratory route.

If only such a proactive approach could be taken with other species that are not protected in Hong Kong, such as the whale shark.

Glimmer of hope for Pacific tuna - but only a glimmer

2009-01-01T17:20:00.002+08:00

An article from Greenpeace international points to weakness in the agreements from Western and Central Pacific Fisheries Commission. This is likely to continue to result in continued overfishing of bluefin and skipjack tuna fisheries. Objections to plans were raised by China, Taiwan, Japan, Korea and the Philippines.

The small glimmer of hope is the banning of purse seine fisheries in two high seas pockets between Pacific Island countries. Click here for description of purse seine fishing

Implications for me are that tuna is mostly off the menu. Albacore tuna is probably still okay.

The end of the Atlantic Bluefin tuna in sight?

2008-12-01T07:40:00.004+08:00

ICCAT, the International Commission for the Conservation of Atlantic Tunas, is a group responsible for the management of fisheries for tuna and related species in the atlantic ocean. The group has enraged conservationists by setting a bluefin tuna fisheries quota for 2009 of 22,000 tonnes, this is 7,000 tonnes higher than scientific advice. Reports are mentioning that the EU skuppered plans by the US to impose the correct limit.

This is really a horrible situation, the death of a magnificent species is at hand.

My suggestion. Write to Joe Borg, EU Directorate-General for Maritime Affairs and Fisheries and/or ICCAT. Contact details as follows:

Bluefin tuna in trouble

2008-10-23T11:33:00.002+08:00

This is an excellent post from the Monterey Bay Aquarium. Have a look at the video as well:

http://www.montereybayaquarium.org/cr/cr_seafoodwatch/sfw_sushi_tuna.aspx

I'm sure we all know what a magnificent animal the bluefin tuna is, however it isn't soft and cuddly like a giant panda and doesn't necessarily get the public attention it deserves, but that doesn't mean that they should not be preserved. From an ecological perspective they are an alpha predator and we don't fully understand what effect removing this animal has on the marine environment that we are dependent on.

We need to stop eating endangered species. The Monteray Bay aquarium does a great job of highlighting the seafood to eat and the seafood to avoid.

I have blogged previously about other regional seafood guides. Have a look.

We should all reduce waste

2008-03-20T09:28:00.005+08:00

This video clip, about reducing our individual wasteful habits, will at first sight seem not related to marine conservation issues. However the huge amounts of plastics and waste thrown into the worlds oceans has a direct and catastrophic effect on the worlds oceans. Plastics are consumed in error and kill multitudes of wild animals. Watch out for the horrific image of the dead bird with its stomach full of discarded cigarette lighters.

Reduction of waste is vital, and not just for reducing the number and size of landfills..

Use of Shark products in cosmetics

2008-02-12T08:31:00.000+08:00

In an article titled "Unilever ends the use of shark products in its cosmetics" Oceana also point the way to consumers needing to be better informed of what osmetic firms are using in their cosmetics.

Quotation from Oceana
“Oceana is satisfied to see that some of the biggest names in the cosmetics industry are recognizing their corporate social responsibilities and choosing not to contribute to the extinction of these important animals,” said Rebecca Greenberg, a marine scientist with Oceana and coordinator of the shark campaign. “We encourage people to become educated and responsible consumers by asking cosmetic retailers about squalene sources and directing their purchases towards companies that have never used this animal-based product in cosmetics or that have made the decision to replace it.”

Actually I was completely ignorant of this use. But not anymore.

Cutting total catches increases profitability

2007-12-10T22:15:00.000+08:00

Research is showing that fishermen will make even more profit than thought if they let stocks rebuild.

The simple reason is that when stocks are plentiful they become easier and cheaper to catch.

This is not rocket science but is a departure from traditional fisheries management, where the maximum highest sustainable catches are set so as to not deplete stocks.

The research shows that there would be higher profits if stocks were kept at a higher level.

"We calculate that we should be conserving about 65% of the virgin biomass whereas at the moment we're down to about 30%."

WWF Hong Kong has launched a shark fin campaign on the 3rd December, aimed at highlighting the

Most shark fisheries are poorly managed and unsustainable.
Huge wastage, 90-95% of the shark is disposed of after the fins are cut off.
20% of the 546 shark species on the IUCN redlist are threatened with extinction.

Hong Kong marine species struggling to survive

2007-12-06T08:39:00.000+08:00

A recent study and press release from WWF-Hong Kong highlights the plight of some of Hong Kong's favourite marine species, including the green turtle, horseshoe crab and chinese bahaba.

Also worth noting is :

"the dire situation facing the globally Critically Endangered Chinese Bahaba and locally depleted Hong Kong Grouper, both well-known edible fish in Hong Kong, were largely unknown to the general public. Mr Alex Fong, Ocean's 10 Ambassador of WWF Hong Kong said, "The polling results show charismatic marine species such as the Chinese white dolphin and Green turtle have received far greater public attention than commercially important fishes"

Sounds like a familiar story. There is a need to focus on better protection not only on individual species but the setup and real complete protection of a variety of marine habitats.

Whaling starts again in earnest

2007-11-27T19:40:00.000+08:00

The Japanese have been routinely slammed in the western press for increasing their planned hunts for whales this year and to include humpback whales for the first time in decades. Under the pretense of scientific research they are planning to kill more than 1000 whales.

"The fleet intends to kill more than 1,000 whales while in the Southern Ocean, including 50 endangered fin whales, 50 threatened humpback whales and 935 minke whales. " Source : Greenpeace

The slaughter of endangered fin and humpback whales is inexcusable. These species are IUCN listed, respectively as

Endangered ("A taxon is Endangered when it is considered to be facing a very high risk of extinction in the wild" source: iucn.com) and
Vunerable ("A taxon is Vulnerable when it is considered to be facing a high risk of extinction in the wild")

However in my opinion.

It would be better in many ways if we did not interfere with the natural world at all, however excluding human extinction this is not realistic or achievable and thus I have no real problem in sustainable fishing of a species, the current levels of hunting minke whales is sustainable
From a conservation perspective, the West's argument about species killing needs to be consistent, not just focused on high profile intelligent or cuddly animals
all species in the world have a right to live whether they are minke whales, napoleon wrasse, corals or ameoba
Inconsistent treatment confuses the conservation and species protection message, we should be focused on ensuring ecological balance, let the natural balance of life work its wonder.

Arguments?

Fish dumping will ruin industry (sic)

2007-11-21T17:06:00.000+08:00

Interesting report on the BBC, sent to me by a good friend, this also made the BBC World Service and BBC News 24. The story is that Europeanfishermen are complaining that because they have already exceeded their fishing quota for various whitefish (cod, haddock and whiting) they have to through away significant quantities of valuable by-catch from allowed prawn trawling.

The report(s) can be found here:
http://news.bbc.co.uk/2/hi/uk_news/7103363.stm
http://news.bbc.co.uk/2/hi/uk_news/7102241.stm

The destruction and wastage is terrible and very very sad of course, but my believe is that the fishing industry is wholly responsible.

Here is my suggestions.

European wide fishing quotas must remain and need to be strictly enforced based on scientific evidence.
Fazing out of trawling within areas of high biodiversity, and introduction of penalities for their use.
Investment into sustainable shrimp fishing and shrimp farming.
Consumer education and labelling into the shrimp industry and the source for shrimps on supermarket shelfs.

The above should also be introduced into the Asia Pacific region as an urgent matter

Fishing ban called for Bluefin tuna

2007-11-10T21:39:00.000+08:00

WWF is calling for a three year closure of the fisheries industry in European waters. The timing of this proclaimation is aligned with the meeting of International Commission for the Conservation of Atlantic Tunas (ICCAT) — meeting from 9 to 18 November in Antalya, Turkey.

This is a follow up to an earlier blog on Bluefin Tuna, click here

Miracle if anything positive comes out of this ICCAT meeting, as there is a history of indecision.

South East Asia's Oceans running out of fish

2007-11-08T10:51:00.000+08:00

A new report from Australia's Lowy Institute spells out what we have all know for a long time, overfishing in South East Asia is depleting SE Asia's fish stocks and coral reefs. Source:Environmental News Network http://www.enn.com/top_stories/article/24297

Few quick points

Fisheries in the region have expanded dramatically in the past few decades
Thailand, Vietnam, Indonesia and Philippines are now inthe top 12 fish producing countries in the world.
In the Gulf of Thailand, the density of fish had declined by 86 percent from 1961 to 1991, while between 1966 and 1994 the catch per hour in the Gulf by trawlers fell more than sevenfold.
In the Gulf of Tonkin, where Vietnam shares resources with China, the record was even worse with fish catch per hour in 1997 only a quarter of that in 1985.
In the Philippines, most marine fisheries were overexploited by the 1980s, with catch rates as low as 10 percent of rates when these areas were lightly fished.
As the fourth largest country in world fish production, Indonesia is a fisheries giant. Yet ... Indonesian marine fisheries resources are close to fully exploited and a significant number in all areas are over-exploited.

Recommendations in the report include

Help Southeast Asian countries build their capacity for fisheries management.
The principle of stakeholder inclusion in its fisheries interventions by stressing the importance of including views from fishers’ representatives, environmental organisations, community and women’s interests, consumers and the private sector representing the retail, food service and fish processing sectors.
Substantial increase in the amount of marine conservation research.
Regional bodies such as APFIC, ASEAN and SEAFDEC need to create a regional process to assess fisheries resources and to provide advice to fisheries managers in a form suitable for local use.
Consumer information, correct labelling of country and source of origin, in an effort to increase awareness of and pressure for sustainable fish products as well as combat illegal fishing.

Hoi Ha Wan - A marine park in Hong Kong

2007-10-23T14:08:00.000+08:00

Hoi Ha Wan is one of four marine parks in Hong Kong. It is located in the North East of Hong Kong, geographically located in SaiKung, it is actually under TaiPo District council.

Under Hong Kong legislation marine parks are protected to some degree,the following picture, taken in Hoi Ha, indicates the activities not allowed :

The key points are that fishing is still permitted in the Marine Parks, to licensed fishermen and that the park is not adequately policed. On a visit during the weekend of the 20th October 2007, I found the following character right on the beach under Hoi Ha Wan village and a stones throw from the AFCD office.

Unfortunately at the time I took this photo I could not tell that he had a seastar in his hand, otherwise I might have spoken to him, as he walked away I could see that he had a nine inch long divers knife, strapped to his leg. One can only guess what he was looking for, however what ever is it he should not be doing it..

There is a growing disquiet in Hong Kong about inadequate protection of marine life AND about the lack of knowledge about the issues. All things marine are seen as inexhaustible.

Apo reef - fishing banned

2007-10-10T06:12:00.000+08:00

Apo reef is a beautiful and relatively remote place, that compared to many other parts of the Philippines is relatively unpopulated, however significant parts of the reef have still suffered from some serious abuse through over fishing together with destructive fishing techniques. I have been to Apo reef twice in 1994 and 2002 and did enjoyed some good diving on some of the dive sites.

Apo Reef (note: not the similarly named Apo Island, a marine reserve off Negros Island in the Southern Philippines) located off the west coast of Mindoro in the Philippines is trying to relive "old glories" and has put into place a total ban from 2nd October on "all extractive activities such as fishing, collection and harvesting of any life form"

Full article, courtesy of WWF-Philippines can be found HERE

One of the key problems with setting up these kinds of No-Take reserves is resistance from the local fishing community, to overcome this alternative sources for fishing have been developed, through installation of overshore fish aggregation devices. A local solution to the local situation, resistance will persist, but hopefully with increased fish aggregations and increased tourism, the project will be successful.

A worthwhile project to support and I hope to visit sometime soon.

The Harm of Good Intentions - turtles

2007-10-08T13:25:00.000+08:00

Came across an interesting argument and perspective on the issue of keeping turtle hatchlings and releasing them until they are stronger.

The argument of this article posted on the WWF Philippines blog puts forward a compelling argument as to why turtle hatchlings should be left and not collected, fattened up and then release later. Essentially the argument is as follows:

Within the first 24 hours of life turtle instinct is to go out beyond the surf zone to catch major currents. They are carried to development areas where they remain until strong enough to migrate distances, it is during this period that the turtles learn about the currents and their migration routes. Key to their survival.

The turtles reproduction process has proven very successful, without human intervention and has enabled the turtles to out live the dinosaurs.

Obviously turtles need a helping hand when human interference is affecting the survival, such as egg collection or fishing by catch but other than that, maybe we should leave them alone...?

Are they right..?

Shrimp/prawn farming - the bad news in detail

2007-09-23T03:25:00.001+08:00

I have known for a while that eating prawns are bad and should be avoided (see other posts on this blog) Prawns/shrimp are either caught using highly destructive trawling or farmed using methods that are highly destructive to marine and coastal ecological systems.

The following two links provide some more information and are interesting reading.

Hungry for change: EJ Foundation campaign for ethical shrimp (read prawn) farming and fisheries: click here

Details report into the shrimp industry : click here

The conclusion of the executive summary section of the "...costing the earth" report says:
"Immediate action is necessary by all stakeholders and specifically governments, the shrimp farming industry, seafood producers, traders and retailers plus aid and development agencies, which together are promoting or indirectly supporting the unsustainable and unethical practices of this industry."

The consumer guide references a need to be aware of what you are eating, ask the right questions of the restaurants and supermarkets and only buy ethically produced prawns.

Now that is the challenge. I don't see any labels or information to help consumers in this regard, maybe if we started to ask then this will start to happen.

EU closed Bluefin tuna fisheries for the rest of 2007

2007-09-20T10:48:00.000+08:00

Due to the reaching of quotas for the year. This affects Cyprus, France, Greece, Italy, Malta, Portugal and Spain. The European Union Fisheries Common fisheries policy set a target to ensure the long term survival of tuna. This includes reducing the amount caught, banning the use of spotter planes and ensuring fish smaller than 30Kgs are returned to the sea. Fisheries policy in the EU has not been very successful in the past but hopefully this will be adhered to and successful.

There are three bluefin tuna species, all provide the highly prized flesh for sushi and shashimi in Japanese restaurants worlwide. All species are critically endangered due to overfishing.
Northern bluefin tuna (Thunnus thynnus)
Southern bluefin tuna (Thunnus maccoyii)
Pacific bluefin tuna (Thunnus orientalis)

We should all reduce consumption of this fish. See the seafood guides for more information:

Malaysian ministry bans shark's fin soup

2007-09-17T15:19:00.000+08:00

Just received this:

"Ministry bans shark's fin soup - Malaysiakini.com ( http://malaysiakini.com/ ) Sep 15, 07 4:16am

Malaysia's Natural Resources and Environment Ministry has struck off shark's fin soup from the menus at official functions, to help conserve the species, a report said today.

Minister Azmi Khalid told the official Bernama news agency that the ministry had made the commitment to the Malaysian Nature Society.

"By refraining from the consumption of shark's fin soup, it is hoped that the ministry would contribute in one way or another towards the current conservation efforts for sharks species," he said.

"Their demise would start off a domino effect, which at each stage could result in the depletion or overpopulation of other fish and marine species leading to an imbalance in the marine ecosystem," he said.

On preservation drive

The society's Selangor branch Marine Group is on a drive to encourage individuals and organisations to stop serving the delicacy at corporate functions.
The marine group had embarked on a series of activities and programmes to promote awareness on the plight of sharks and their importance to the marine ecosystem.

Malaysia's population is dominated by Muslim Malays, but there are also large ethnic Chinese and Indian communities."

What can be done to raise the awareness of this and to try to get other governments and ministries in the region follow suit...?

Dead blacktip shark in Hong Kong marine park

2007-09-10T18:21:00.000+08:00

A juvenile blacktip shark (note : Not blacktip reef shark, description HERE) was caught in a fishermen's net in Hoi Ha Wan marine park.

Check out the following story:
http://www.news.gov.hk/en/category/environment/070830/html/070830en04003.htm

This has opened up the debate about whether fishermen should be allowed to fish in marine parks. The HK government does allow a limited number of fishing permits to be issued annually.

I don't think any fishing should be allowed in designated marine parks.

FAO plan for conservation and management of sharks

2007-08-31T15:01:00.000+08:00

CORRECTION

Carrying on with the theme of Sharks and Shark fishing, The Food and Agriculture Organisation of the United Nations, ratified an "Action plan for the conservation and Management of Sharks'.

On the website of the FAO the only countries that have put together and published a plan for sustainable shark fisheries are Canada, Japan, Australia, Mexico, Taiwan, United Kingdom, United States, Malaysia, and Ecuador, as well as a Mediterranean wide plan.

However the action plan is voluntary and not legally binding. Bad news is that the Ecuadorian government in early August has lifted the ban on sales of shark fins. This is politically motivated move by the president to court fishermen prior to a up coming election. (source: guardian.co.uk)

The European Union are also guilty of killing huge numbers of sharks and recent attempts to list the Porbeagle and Spiny Dogfish onto CITES was not ratified. These species are consumed in Europe at alarming rates with the fins being sold to China.

All divers appreciate and love to see sharks, and they are a vital part of the marine ecology, isn't it time more was done to protect and enforce international legislation and protection of sharks.

FYI. The FAO website lists the aims of a national shark-plan should be to:

Ensure that shark catches from directed and non-directed fisheries are sustainable
Assess threats to shark populations, determine and protect critical habitats and implement harvesting strategies consistent with the principles of biological sustainability and rational long-term economic use
Identify and provide special attention, in particular to vulnerable or threatened shark stocks
Improve and develop frameworks for establishing and co-ordinating effective consultation involving all stakeholders in research, management and educational initiatives within and between States
Minimize unutilized incidental catches of sharks
Contribute to the protection of biodiversity and ecosystem structure and function
Minimize waste and discards from shark catches in accordance with article 7.2.2.(g) of the Code of Conduct for Responsible Fisheries (for example, requiring the retention of sharks from which fins are removed)
Encourage full use of dead sharks
Facilitate improved species-specific catch and landings data and monitoring of shark catches
Facilitate the identification and reporting of species-specific biological and trade data

Sharkwater - the movie

2007-08-22T15:09:00.000+08:00

A critically acclaimed film about the plight of sharks is currently been released in North America.

Have a look at the website and trailer by clicking http://www.sharkwater.com/ the film does put across a very important message.

Unfortunately the film is not yet due for release in Asia as the producer :
"We would love to have the film release in China and Hong Kong but unfortunately we have seen some resistance"

I am currently seeing whether there are ways that this can be released in Hong Kong and China but I have limited influence or contacts in the cinema/film distribution industry. Anyone have any ideas?

Intro to marine organisms - 2

2007-08-12T21:26:00.000+08:00

Another quick break from conservation issues to write an introduction to some more undersea creatures, a good educational process for me so hopefully for others.:

1. Octopus (Octopus Sp.)

A member of the mollusc family, the octopus has no skeleton and is a master of disguise. Their amazing ability to change colours and skin texture enables them to almost literally disappear into the background. You only really see them if they happen to move or if you are particularly eagle eyed.

Octopus, he knows he has been spotted and rapidly changes colour, to show his
(her?) annoyance before squeezing into a tiny crevice

Octopus are clearly highly intelligent and in experiments have been shown to have maze and problem solving abilities. Octopus are not currently endangered however they are popular food animals.

2. Emperor Angelfish (Pomacanthus imperator)

A spectacularly beautiful fish that reaches upto 40cm in length however they are more typically upto 30cm in length. The picture below is a mature animal, juveniles have a completely different coloration and pattern, with concentric blue and white circular lines on a dark blue background.

Emperor angel fish been cleaned by resident 'cleaner wrasse'.

Most angelfish are seen in pairs that are highly territorial, never locally common, angelfish are sometimes captured for the aquarium trade, a practice that should be discouraged given the difficulty and territorial nature of the animal.

3. Sponges

Sponges are extremely common and are thus a highly successful animal, earliest fossil records have sponges as much as 1000 million years old. They take many forms for instance a red encrusting sponge is shown in the emperor angelfish picture above through to the largest species, the barrel sponge. Sponges are the most primitive of multicelled animals and are pretty much a colony of individual cells, they have no muscles, nerves, true tissues or internal organs.

Tubular sponge, photo taken in Komodo National Park, Indonesia.

Sponges are filter feeders and form an important part of the reef ecology, acting as 'hosts' to a menagerie of smaller organisms. Some species are commercially important, harvested to keep us clean as we take showers.

4. Snapper

This is a diverse fish family that are both important predators on reefs as well as important commercially caught food fish. There are more than 100 species worldwide, most of these are found around the western pacific region. Many species form large schools, the species below typically is solitary waiting over reef shallows waiting for suitable food to come swimming by.

One spot snapper (Lutjanus monostigma) in a typical reef scene in
relatively shallow water (12m). A swarm of reef fish that also includes
goat fish, damsel and parrotfish. Photo from Puerto Galera, Philippines

5. Maxima clam (Tridacna maxima)

Related to the giant clam, the maxima clam is a brightly coloured mollusc that is closely related to the giant clams (which is now a increasingly rare animal) They attach themselves to the reef and grow slowly, competing with corals and other invertebrates for space and access to sunshine.

Maxima and giant clams have a close and dependent relationship with algae (zooxanthellae) that gives the animal it's vibrant colours. Due to this dependence Maxima clams are found in the shallow areas of reefs, where there is a lot of sunlight.

Seafood guides - global selection

2007-08-09T10:24:00.000+08:00

There are various seafood guides available globally, they are not exactly the same, being focused on local market conditions, unfortunately on an initial look, they also appear to promote local fisheries or aquaculture and may not be unbiased (subject to detailed analysis..!)

2007-08-02T08:42:00.000+08:00

Some great news...

Mid July 2007 a total of 61 green turtles (Chelonia mydas) were released at Tai Long Wan in Hong Kong's North Eastern, Sai Kung country park.

Heading out to open sea, photo from http://www.news.gov.hk

The juveniles were under the care of AFCD and Ocean Park staff since their mother laid eggs on Tai Long Wan last September and have grown from 25g to 800g in weight and 5cm to 16cm in shell length. This will give the youngsters a fighting chance of surviving and returning to Tai Long Wan.

All of the youngsters were micro chipped for future identification.

Story on the HK government website can be found Click HERE

The green sea turtle is an endangered species, under threat from habitat loss, pollution, fishing by catch and hunting/over exploitation.

Dolphinariums and dolphin drives

2007-07-29T19:39:00.002+08:00

Recently visited the Taiji Whale Museum in Wakayama prefecture, Japan.

Taiji Whale Museum

This is an "entertainment" facility that show the history of whale hunting, methods of hunting over the ages, various whale skeletons, there are also captive false killer whales, a single killer whale, Risso's dolphins and short finned pilot whales. Also what is on offer is a dolphin petting experience using a female bottle nosed dolphin.

Risso's Dolphin at the Taiji Whale Museum

There is an educational aspect to the "museum" in that tourists are able to see and have a positive experience with these various cetaceans. However at what cost... there is a darker side to Taiji and it's Whale Museum.

Many people will be familiar with or heard about Dolphin drives in Japan and the brutal nature of the slaughter (check out the following website Click HERE) Actually the Taiji Whale Museum has been implicated in these hunts. A certain percentage from the hunts are taken aside by the Taiji Whale museum to provide for the dolphin petting experience or to provide live cetaceans to Oceanariums worldwide.

Ocean Park, Hong Kong has done some studies into Mainland Chinese oceanariums/dolphinariums and where they source their dolphins and I have sent an enquiry to them for some information.

Taiji Whale Museum and any oceanarium that sources from this brutal slaughter are to be avoided at all costs.

Of course this brings the bigger question of whether we should have dolphins and other cetaceans in captivity at all.

Alaskan fisheries authority react quickly and close down commercial fishing

2007-07-05T15:52:00.000+08:00

Interesting article passed to me by Alison Bradley (thanks Alison) points to a link between climate change and the stalled recovery of the 'overfished' cod fisheries in the North West Atlantic.

This link in a report by the University of Massachusetts, has led to the North Pacific Fishery Management Council making history by "summarily prohibited any bottom-trawl commercial fishing off the far north of Alaska past the Bering Strait — at least until scientists figure out the effects of sea ice retreat and warming."

The full story can be found HERE

The fast action of the Alaskan fisheries authorities should be applauded, fast and decisive action from scientific evidence is needed in many others areas, here's a few that immediately come to mind:

European fisheries in the North Sea and the Atlantic, near collapse.
WWF-HK's call for no catch zones in Hong Kong waters. Setting up of marine parks has seen little recovery
Bluefin tuna worldwide, a species now critically endangered.
The live fish trade in South East Asia, both due to unhealthy fishing practices and overfishing.
Shark finning, absolutely unsustainable.

Sea Turtle Conservation and Tourism Clash on Japan's Yakushima Island

2007-07-04T16:22:00.000+08:00

An news item of interest that I have found on ENN (environment news network)
http://www.enn.com/net.html?id=2025

Essentially this article talks about how growing ecotourism on the island of Yakushima, Japan, is damaging the nests of the endangered North Pacific Loggerhead turtle.

To me this shows the increasing interest and thus the increasing value in environmental tourism, but clearly not all Ecotourism is created equal. Care must be taken to research and choose appropriate conservation enhancing Ecotourism destinations that also directly benefit local people. If you don't like what a tour group or "Ecotourist" site is doing, don't participate and publicise, on this BLOG and others, what you don't like.

Intro to marine organisms - 1

2007-06-28T17:48:00.000+08:00

Just for a change of track, how about a few photos and a very quick intro to a few undersea creatures.

1. Nudibranch. The following guy is called Chromodoris willani, not many Nudibranch's have common names. The photo was taken in Puerto Galera, Philippines. Nudibranch are members of the mollusc family and are characterised by the presense of external gills, normally visible on the top near the back of the animal. Extremely colourful, like they have come off a painters easel there are more than 2000 species known worldwide.

2. Teira batfish. (Platax teira) A schooling fish, territorial and curious they will often come in close to see what you are doing.

3. Mantis shrimp. A crustacean often found scurrying across sandy patches and under rocks and coral outcrops. There are many different subspecies, but typically they have a jack hammer appendage used to smash open the tough shells of their main prey, crabs. Their eyes are mounted on two stalks and are said to be the most complex of any animal (for instance each individual eye is capable of trinocular vision and depth perception). A fascinating creature.

4. Sea apple (Pseudocolochirus violaceus) , the sea apple is a colourful sea cucumber, capable of withdrawing into a ball the photo illustrates the animal extending its tenticles.

5. SeaStar (the correct common name for star fish) there are many different types, many strikingly beautiful and can easily be seen when diving or snorkling. Seastars are members of the Echinodermata family and closely related to sea cucumbers, sea urchins and feather stars.

6. Whip coral. This yellow specimen in the photo has its polyps extended, a number of small reef fish can be seen in the photo as well (anthia, wrasse, chromis).
Corals as a whole are members of the Cnidaria family and are closely related to sea anemones and jellyfish (amongst others) the polyps are individual animals that form large colonies. Many types of corals have built massive structures (e.g. the great barrier reef), these structures form arguably the most diverse ecosystems on the planet and vitally important for the overall health of the oceans. Unfortunately they are highly vunerable and increasing under threat.

Sources for environmentally sustainable shrimps/prawn

2007-06-22T19:11:00.000+08:00

I've done some research and I have had some success in sourcing more environmentally sustainable sources of shrimp/prawn. Here is a quick synopsis of what I've found out....

US Farmed Shrimp. Some of these farms are located far away from the sea and are re-circulating, closed-water systems that rear the shrimp in tanks.
Caveat : no clear way to know, as far as I can tell, where the shrimps are exactly farmed. As a reminder, typically shrimp farms are located on the coast causing significant environmental impact to susceptable coastal ecosystems.
Organic shrimp. In the absense of formal Shrimp Aquaculture certification, there are a few shrimp farms that are certified organic, these do aim to supply shrimp without the use of chemicals, antibiotics, hormones or preservatives. Some of these farms are located in Florida and Ecuador.
Caveat : Certified Organic doesn't necessarily mean environmentally sustainable.
Spot shrimp. Caught in temperate seas off Alaska using Traps.
Caveat : Signs of overfishing. British Columbia shrimp fishery 'is fully fished, status of other fisheries is unclear' source - Seafood choices alliance

Another finding of note is that attempts in Thailand to place shrimp farms away from susceptable coastal areas suffered a set back with the Thai government banning this practice since 1999. The reason was that the waste from the shrimp farms left potential farm land ruined. Typical shrimp farms typically only work for a few years before the land has to be abandoned. It has been estimated that to return the land back to 'normal' takes 30 years. Source : Wikipedia

All in all not really a pretty picture. I continue to avoid shrimps or prawns.

Chinese turtle boat with 397 dead sea turtles aboard discovered

2007-06-13T14:44:00.000+08:00

May 8th , 2007. Chinese registered vessel with 397 dead and stuffed turtles aboard was found in the Indonesian waters around Kalimantan.

Source: http://www.turtle-foundation.org

In China turtles are considered a symbol of longevity and presumably these were destined as cheesy decorative pieces in office receptions and the bosses living room.

The following was the grusome findings from the seizure.

296 Hawksbill Turtles, a critically endangered species. Treated with formalin, size of carapace: 20 - 90 cm
90 Green Turtles, an endangered species treated with formalin, size of carapace: 20 - 90 cm
1 Olive Ridley Turtle, also an endangered species.
4 cans of formalin with 25 liters each, 100 Liter in total
17 nets with 38 cm nitting distance
3 giant mussels, approx. length: 100 cm
1 stuffed pufferfish
2 speedboats with 60-PS-engines

Conservation of sea turtles in Hong Kong

2007-06-02T08:06:00.000+08:00

In direct response to Peter's question (see here) about the Sham Wan Beach and essentially conservation efforts in Hong Kong to protect the only nesting site for Green Turtles.

Actually a lot is done to protect the beach area during the potential nesting period, teams of volunteers and staff from the AFCD aim to make the beach as hospitable as possible and illegal entry onto the beach is subject to a maximum fine of HK$50,000.

More information can be seen click here

Green turtle nesting season is starting in Hong Kong

2007-06-01T08:16:00.000+08:00

In Hong Kong the Shum Wan bay on Lamma Island is a protected beach, this is the only beach in Hong Kong where Green Turtles have, in the recent past being known to nest.

"The Green turtle nesting season has run from June to October in the past but numbers returning have dropped to perilously low levels in recent years. Ever since 2003, no Green turtles (Chelonia mydas) have nested at the Sham Wan beach on Lamma Island, which is the only site where Green turtles have nested regularly in recent decades. "
Source: WWF Hong Kong e-News 31st May

WWF also requests the following actions to encourage Green turtles to return

Support WWF's Save our Seas (SOS) campaign to prevent our marine ecosystem, where marine turtles rely on, from collapsing.
Beach visitors, divers etc should avoid disturbing any marine turtles in the water or at beaches identified for marine turtle nesting, i.e. Sham Wan and Tai Long Wan, as a passive effort to encourage turtles coming back to Hong Kong for nesting.
Report any sightings to AFCD by calling 1823 during this coming June to October nesting period!

Sustainable fisheries or aquaculture (seafood farming)

2007-05-31T11:39:00.000+08:00

I have doing some detailed research into sustainable sources for seafood. My initial findings are mixed, here are my initial thoughts and findings.

Sustainable fisheries.
The Marine Stewardship Council, undertakes a detailed certification process for world fisheries. WWF Hong Kong is heavily relying on MSC certification for their Seafood Guide (click HERE for previous BLOG on this topic)

The process of certification can take upto 2 years to complete (as can be seen from the certification application of the "Hastings Fleet Pelagic Fishery", this assessment lasted from October '03 to September '05)

The list of MSC certified fisheries can be found click HERE

The list contains many North American, European and Australian fisheries and contain a variety of seafood species, however no Asian fisheries or shrimp/prawn fisheries have been certified.

Sustainable Fish Farming
There is an Asia Pacific Organisation "Network of Aquaculture Centres" " is an intergovernmental organization that promotes rural development through sustainable aquaculture", click HERE for their website.

NACA in collaboration with the Food and Agriculture Organisation of the United Nations (FAO) has initiated a certification process for sustainable Aquaculture click HERE for notes about this certification. As far as I can tell no certificates have been issued and as can be seen from the information on the NACA website their major focus is on farming and rural community development. This certiffication process is only playing lip service to the issue.

Further potential confusion is the Thai Quality Shrimp certification (click HERE) Their Good Aquaculture Practice guidelines, even though they state, should not generate any environmental impacts are focused on producing a consumer safe product.

Groups such as NACA and Thai Quality Shrimp have no real interest in environmentally sustainable seafood farming and as such these efforts should be ignored from this perspective.

The Hong Kong Agriculture,Fisheries and Conservation Dept (AFCD) has an "Accredited fish farm scheme", this again is focused mainly on production of a safe product for the end consumer.

The is obviously space for certification and following through with identification of sustainable seafood farms, however this is not yet obvious.

No real conclusions yet, my investigations will continue.

Indonesia protects 900,000 hectares through network of Marine Protected Areas

2007-05-24T10:51:00.000+08:00

Here's some good news.

Through the setting up of seven separate Marine Protected Areas (MPA's). A vast 900,000 hectares of tropical water are newly protected in the Indonesian archipelago of Raja Ampat. Raja Ampat is in the far east of Indonesia, bordering the Island of West Papua and is well know as Marine Biodiversity Hotspot. Click HERE for an overall map of the area.

This announcement by the Indonesian Minister of Marine Affairs and Fisheries Mr. Freddy Numberi, was as a result of efforts and campaigning of the local Fishing Communities and NGO's organisations such as Conservation International.

What has been happening in the recent past is that because of encroachment by non local commercial fishing boats in the area the local fishing communities have been suffering increasingly from reduced catches, threatening local livelihoods. Local communities will be jointly managing the MPA's.

The area can be visited and there are a number of liveaboard operators in the area (For example, MV Bidadari, who I dived with recently in Komodo, has a sister ship Sevens Seas, that operates in the area)

Full report from Conservation International, can be found Click HERE

Countries with the largest coral reef systems

2007-05-21T16:29:00.000+08:00

I was trying to find out the comparison of the total areas of reef coverage by country. The following table extracted from the UNEP (United Nations Environment Program) website, shows twenty countries with the highest total reef areas (areas in square km's)

Source : UNEP, orginal can be found here HERE

A little surprised that the Maldives was quite so low, given the size of the atolls. Other countries of note:

Sudan, ranked 24, total area 2,720

Thailand ranked 26, total area 2,130

Mozambique, ranked 28, total area 1,860

Belize , ranked 33, total area 1,330

Palau, ranked 39, total area 1,150

Napoleon wrasse on menu - AFCD response

2007-05-16T08:08:00.000+08:00

Further to the earlier posting, I have received a very informative response from Tony Wong, Senior Field Officer (Endangered Species Protection), Agriculture, Fisheries and Conservation Department

"Thank you for your information and enquiry regarding possession of humphead wrasse (Cheilinus undulatus) for commercial purposes.

Please be advised that humphead wrasse was newly controlled in Hong Kong under the Protection of Endangered Species of Animals and Plants Ordinance since 1 December 2006. For those newly listed species, the Ordinance permits a 6-month grace period during which a restaurant may apply for a possession licence for those humphead wrasse acquired before the Ordinance came into effect. The grace period will expire on 31 May 2007. By then, a restaurant should have a valid licence to possess humphead wrasse for commercial purposes.
According to our record, an application for a possession licence is not yet received from the concerned restaurant. Nevertheless, we have taken note of the situation and will keep this in view for any necessary action. "

Very informative response....!

Napoleon wrasse on menu in HK restaurant

2007-05-15T07:50:00.000+08:00

Unfortunately on Saturday 12th May, I spotted two juvenile Napoleon wrasse (Cheilinus undulatus) in a Hong Kong restaurant. Please see the picture here (not that clear, sorry)

Juvenile (35cm) Humphead/Maori/Napoleon wrasse (take your pick)

destined for the pot, BUT isn't it a protected species?

The restaurant was the Victoria Seafood restaurant, 5th floor, CITIC centre, Central, Hong Kong.

I have sent an email to both the AFCD (Agriculture, Fisheries and Conservation Department), HKU and the WWF to seek clarity on whether the restaurant has the required CITES import permits.

This is a beautiful fish that does need protection to ensure its survival.

Saving the Sea's Bounty - National Geographic

2007-05-11T13:59:00.000+08:00

The April edition of National Geographic "Saving the Sea's Bounty" includes a number of good articles. Here is a quick synopsis of the contents:

The Global Fish Crisis: high tech fishing is 'gutting' the world oceans. Many species have declined by 90%. Have a look at one sample photo ("shrimp bycatch cascade of death"), that illustrates the tremendous waste.

Blue Haven. In New Zealand a number of no take marine reserves are having amazing results and increasing the fish catch (by overspill from the reserves) Started by Bill Ballantine, local fishing communities are now avidly supporting this idea. Why can't it be done in other areas, as avocated by WWF-HK.????

End of the Line. A well know story of the complete collapse of the Newfoundland Cod Fisheries. A clear example of the real human effects of unsustainable fishing.

This edition of the National Geographic is a good read.

Additional Seafood guide - have a look

2007-05-07T17:01:00.000+08:00

Being aware and careful about what we eat is a clear way to influence the major problem issues of overfishing, destructive fishing techniques and non sustainable seafood farming.

As the slogan goes:

If the buying stops the killing can too..

I have found another very informative seafood guide, which can help us to be better informed and to become advocates for sustainable seafood. This can be accessed here

This is from the Monterey Bay Aquarium, it is a little US centric but I like it... why?

Lots of information about what you should eat and what you should avoid.
Easy to search and browse for a particular species.
You can see what the fish/shell fish looks like. Very helpful.
I think there are some additional ideas here that WWF can use to spice up their Seafood guide and campaign. I will send this onto them.

Click on the "WHAT YOU CAN DO" link. I have gone further and made a pledge to become a Seafood Watch Advocate. Watch out...!!

Status of South East Asian Coral Reefs

2007-05-03T10:06:00.000+08:00

This is a broad subject that I am currently researching further. However this graph, is useful pictorially about what has been happening to Coral Reefs throughout South East Asia.

Source : GCRMN

Original found here

The longer the blue lines, the better and the shorter the brown line the better. I am not exactly sure of the methodology taken on this survey but my take on what this is showing is that between 1994 and 2004:

Indonesia has shown an improvement, critically the only country to show a decrease in the amount of coral reefs with less that 25% live coral cover (LCC)
Malaysia has also shown an improvement, but only in the >75% LCC category.
Vietnam has the biggest decline in LCC. Their reefs look in critical trouble.
Myanmar's reefs look the healthiest. But no indicator of the status in 1994. Also should be noted that Myanmar has no GCRMN co-ordinator.
Philippines has also seen a significant decline in this ten year period, especially with regards to the less than 25% LCC category.

The biggest risks to the reefs were listed as overfishing and destructive fishing.

This survey does not indicate the total area of reef coverage in those perspective countries.

Napoleon wrasse taken off the menu in Manila

2007-05-01T12:23:00.000+08:00

A follow-up to my recent posting of 'mameng' on the menu in a Manila restaurant. Actually found out that the restaurant in question, Portico's has removed the item from their menu.

So public campaigns can make a difference and make changes (not that I had anything to do with this particular case)

South China Sea: Scarborough Reef used as target practice.!

2007-05-01T11:36:00.000+08:00

This is an interesting one, that I have just discovered whilst browsing.

Scarborough Reef, located 200kms to the west of Subic Bay is an area of great biodiversity:

"The U.S. military used the reef for bombing practice during the 1990 confrontation with Iraq, complicating matters. Large and unique underwater dunelike structures of organ-pipe coral tens of meters long were used as targets. Substantial areas of coral were torn apart by the explosions."

Closure of coral beach in Hoi Ha Wan Marine Park

2007-04-30T22:07:00.000+08:00

The Hong Kong Agriculture, Fisheries and Conservation Department announced in a notice dated 27th April the closure of the 'Coral Beach' in Hoi Ha Wan Marine Park. This is with the objective of :

"prohibiting the entry of all persons and vessels into the Area are for the protection of corals by reducing human activities and impact in the Area"

Seems a step in the right direction, however it is still possible to fish in other parts of the park with the correct permit.

Still some way to go..

Whale shark rescues in India

2007-04-29T11:34:00.000+08:00

The Wildlife Trust of India whaleshark campaign seems to be reaping results. Shown by the fifth whaleshark rescue in the last two months.

http://www.wildlifetrustofindia.org/html/news/2007/070416_whale_shark_rescue.html

Indian fishermen are compensated Rps25,000 for saving whalesharks caught in their nets. This appears to contrast to what is happening in other areas.

" use of the Whale Shark for food is mainly for its meat and has been documented in Taiwan, India, and the Philippines. Work carried out by TRAFFIC in co-operation with researchers at National Taiwan Ocean University in 1996-1997 identified Taiwan as a major, and possibly the largest, market for Whale Shark meat. " source: traffic.org

It should be noted that Taiwan is introducing innovative ways to ensure sustainable trade in Whaleshark meat.

Komodo National Park - mooring buoy project

2007-04-28T22:42:00.000+08:00

Komodo National Park is located in the centre of the Indonesian Archipelago between the islands of Sumbawa and Flores. It was declared a national park in 1980 and in 1986, the Park was declared a World Heritage Site and a Man and Biosphere Reserve by UNESCO, both indications of the Park's biological importance.

The Indonesian and Philippines archipelagos are the epicentre of the worlds marine biodiversity (exact location subject to some debate, try to google 'marine biodiversity epicentre' for some intriguing differences of opinions) Komodo is certainly a magical place, great diving, huge variety of things to see underwater and fantastic scenery above sea level. To add to this is the unique terrestrial ecology of Komodo and Rinca islands.

With the recent increase in dive boats operating in the Park, an extensive mooring buoy project was initiated by Helen Newman. This project had the active involvement of the diving community in Komodo and was completed in February 2007. Coincidently this was when I was diving in the Park on the live aboard dive boat, MV Bidadari. We were the first boat to utilise a few of the new buoys.

Ouch, the potential damage to reefs is
obvious

This is the kind of project that will make a real difference and is one piece that will help to ensure the survival of this unique marine reserve. Other challenges still exist, but that is another story.....

The full final report on the mooring buoy project can be read by clicking here

Are there any other worthwhile projects out there that should be mentioned?

Whale sharks

2007-04-27T12:38:00.000+08:00

Whale sharks are elusive and difficult to spot. They are the largest fish in the sea but certainly a gentle giant. Primarily feeding on zooplankton as small as 1mm.

A great friend of mine, Peter Emmett, just had a wonderful trip to Donsol in the Philippines, where he snorkled with a number of sharks. Donsol does apparently have the highest density of whale sharks anywhere in the world. (source:Wikipedia) So head down there. Bringing in hard needed revenue to the local fishermen (who traditionally hunt whale sharks) is a great way to ensure its survival.

Thanks also to Peter for pointing out to me whaleshark.org, a not-for-profit organisation working to protect the threatened whale shark. One thing they are aiming to do is to have a photo library of whale shark encounters, to aid in further research. So...

If you do see a whale shark and happen to have a camera in hand, please take a photo (importantly of the pectoral fins and the pattern of spots above and around them) and send to http://www.whaleshark.org/

(more info on what they want, can be found on the above website)

Tiger Shark Feeding video clip - Scary....!!

2007-04-26T08:11:00.000+08:00

Clip from "You Tube" showing a shark feed dive in Fiji. Hand feeding a large (3.5 - 4 metre) and very fat Tiger Shark seems absolutely crazy to me. Also check out the worlds fattest Grey Reef's and a one 'normal' non obese Silver Tip. Fish soup as well..

Tiger Shark and more - You Tube clip

Question is: "is shark feeding a good idea"

I think there are two opposing arguments regarding Shark Feed Diving

Shark Feeds increase encounters with Sharks and can aid in their preservation, by raising awareness and reducing the mystery around sharks.
In other parts of the world shark feeding has been blamed for the rise in attacks in South Africa. They can become habituated to humans and associate them with food.

I think controlled and well managed shark feeding probably has more plus points that negative.

But for myself, I prefer to see natural behaviour and those unexpected encounters and will vere away from shark feed dives.

Ciguatera poisoning on the increase

2007-04-25T15:48:00.000+08:00

Dozens of popular fish types, including grouper and barracuda, live near reefs. They accumulate the toxic chemical in their bodies from eating smaller fish that graze on the poisonous algae. When oceans are warmed by the greenhouse effect and fouled by toxic runoff, coral reefs are damaged and poison algae thrives, scientists say.

Experts estimate that up to 50,000 people worldwide suffer ciguatera poisoning each year.

Hong Kong has refused to enact mandatory measures to prevent ciguatera despite increased outbreaks. It argues that educating consumers and traders is the answer, rejecting calls to crack down on traders or ban fish from suspect areas.

"Given the fact we eat so much seafood in Hong Kong, this should be one of the priorities in protecting the population," Sadovy said.

350 Napoleon Wrasse released back into Marine Park

2007-04-25T09:59:00.000+08:00

Chinese vessel the Hoi Wan, was caught with 351 live Napoleon Wrasse (listed in CITES appendix II) caught illegally in the Sulu Sea. They were without correct CITES permit, the boat and cargo were impounded. However the crew were released on bail in January and are free.

Eventually the Wrasse were kept alive (with only one dying) near Puerto Princessa, Palawan and released back into the Tubbataha Reef Marine Park (a UNESCO World Heritage Site) at the end of March.

This has caused a stir in the diplomatic channels with the Chinese authorities apparently refusing to admit that this was not only an infringment of territorial waters but a clear endangered wildlife issue. The Chinese CITES authority are refusing to admit the seriousness of the chinese fishing vessels illegal activity.

Email feedback to WWF on their Seafood guide

2007-04-24T13:34:00.000+08:00

With regards to the WWF Seafood guide. On the 10th April, I wrote an email to WWF (seafood@wwf.com.hk) with some initial comments on the Seafood Guide (click here to access guide )

The contents of the email was as follows:

I like the guide, I think that this is a key step in the right direction. Consumer education is absolutely key and this is a good start.
The common names are none standard. I am not familiar with the English names used on this guide. A side guide (maybe online) with photo’s would be helpful. I notice the URL Click HERE has many but not all of the fish listed on the Seafood Guide. Could this be gradually expanded to include all the fish on your guide?
I am concerned about the wild caught Chilean Seabass being on the Recommended list, for two major reasons:

- Chilean Seabass (also known as the Patagonian Toothfish) is fished (in many areas overfished) using long line fishing. This fishing method continues to be indiscriminate and has considerable side catch, this is resulting in a large decimation of albatross and seabird populations in the South Seas.

- How can we know that the Chilean Seabass available in Hong Kong is from the MSC certified fisheries and not from other non sustainable sources..?

- The Wikipedia entry summarises this adequately Click HERE
It is a bit difficult to know where the fish are sourced when you are eating in a restaurant. Could you add some comments how what people can do in these cases. E.g. some questions that they could ask. If the right questions are asked then maybe restaurants would also start to source from sustainable sources.
Are there any recommended sources for Shrimps/prawns. This is extremely popular in Hong Kong and a suitable alternative is needed. At the moment this is only in the AVOID category.
Chinese Oysters are included, however I think that Globally sourced Oysters are also very popular in Hong Kong. Is there any plans to expand the guide to include these as well as other popular seafood ?
For non Chinese I think a phonetic representation of the Cantonese pronunciation would be very helpful.

As of 24th April, I have not yet received a response.

Hi

This is my first attempt at creating a BLOG, it seemed an appropriate moment to try to jot down and share with all my passion for diving and especially for Marine and Coral Reef conservation
