According to Thaphol Somsakul, a civilian dive instructor with the Navy, rare marine species like Giant stingray and Ronin are becoming harder to find in their regular Thai habitats as they are sold to aquariums by fishermen.

Thaphol said he became suspicious after noticing rare species with distinctive marks at various trawler piers, and then seeing them later in aquariums.

“The decrease in number of these species coincides with the increase in the number of new aquariums opening, as well as in the number of rare species on display,” he said, citing his own experience and reports from fellow divers. “I interviewed fishermen who all said those rare species were trapped in their nets by chance.”

Unlike protected or endangered species, rare species are not protected by Thai law. A one year joint project by the Navy, PTTEP, and the NaturalResources and Environment Ministry is however scheduled to inspect 20 sites in the Gulf of Thailand and the Andaman Sea to locate coral reef sites and gather information that will be used in a coming reef conservation project.

Yesterday, French president Nicolas Sarkozy announced that France backs Monaco’s call for an international trade ban for Atlantic and Mediterranean bluefin tuna.

“Ours is the last generation with the ability to take action before it’s too late – we must protect marine resources now, in order to fish better in future. We owe this to fishermen, and we owe it to future generations,” said president Sarkozy at the close of a national stakeholder consultation on France’s future sustainable fisheries and maritime policy, the ‘Grenelle de la Mer’.

This means that France joins the growing list of countries and marine experts that wish to place Bluefin tuna under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) to give the populations a chance to recuperate.

“WWF welcomes the Monaco initiative and the position of France, whose fleets have traditionally caught more bluefin tuna than any other country,” said Dr Sergi Tudela, Head of Fisheries at WWF Mediterranean.

The Principality of Monaco was the first state to announce its willingness to sponsor a proposal to ban international trade in Bluefin tuna and the country is now seeking the support of other states in whose waters this species lives.

“In terms of eligibility for a listing on CITES Appendix I, Atlantic bluefin tuna ticks every box – and then some,” said Dr Susan Lieberman, Director of WWF’s Global Species Programme.

The next CITES conference will be held next year in Qatar, but proposals have to be submitted by 17 October to be eligible for consideration.

The Netherlands now join Norway in the effort to save the European eel Anguilla anguilla from extinction.

Yesterday, the Dutch government announced a two-month long ban on eel fishing that will commence on October 1 this year, followed from 2010 with a yearly three-month prohibition from September. In 2012, the new regulation will be reviewed and its effectiveness assessed.

“I realise this is a very big sacrifice for eel fishers, but ultimately it is also in the interests of the industry that eel numbers are allowed to recover,” Agriculture and Environment Minister Gerda Verburg said in a statement.

Before the regulation can be put into action it will however require the approval of the European Commission. The commission has already rejected a Dutch proposal to enlist the aid of eel fishermen to help boost the eel population by releasing 157 tons of mature, caught eel close to the species spawning waters in the Sargasso Sea.

“The (initial) plan would have offered guarantees for the recovery of the eel population,” the professional fishers’ federation Combinatie van Beroepsvissers said in a statement, describing the new measure as “incomprehensible, unreasonable and unacceptable”.

Eel is a delicacy in the Netherlands and roughly one thousand tons of eel are caught in Dutch waters every year. The Dutch government have designated 700,000 Euros (989,800 USD) to aid the estimated 240 small fishing businesses affected by the eel ban.

As of August 12, 2009 the harvesting of krill in the in the Exclusive Economic Zone (EEZ) off the coasts of California, Oregon, and Washington will be prohibited by federal law.

Yesterday, the U.S. National Oceanic and Atmospheric Administration (NOAA) published a final rule in the Federal Register prohibiting the harvesting of krill in these three regions. All types of krill harvesting will be illegal, regardless of fishery and gear type.

“Krill are the foundation for a healthy marine ecosystem,” said Mark Helvey, NOAA’s Fisheries Service Southwest Assistant Regional Administrator for Sustainable Fisheries. “Protecting this vital food resource will help protect and maintain marine resources and put federal regulations in line with West-Coast states.”

Harvesting krill within three miles of the coastline of California, Oregon, and Washington has already been prohibited by state law, but the zone situated between three and 200 miles off the coast have lacked krill protection until now.

“This is a great success for protecting the entire California Current ecosystem“, said William Douros, West Coast Regional Director for NOAA’s Office of National Marine Sanctuaries. “This decision reflects strong teamwork within NOAA and a commitment to addressing the issues raised by the Pacific Fishery Management Council and Sanctuary Advisory Councils.”

The krill protection rule was adopted as Amendment 12 to the Coastal Pelagic Species Fishery Management Plan (FMP), which was developed by the Pacific Fishery Management Council (PFMC) under the Magnuson-Stevens Fishery Conservation and Management Act. Amendment 12 adds all species of krill under a new category: ‘prohibited harvest species’.

Norwegian fisheries regulators have banned all fishing of the critically endangered European eel starting in 2010 and cut 2009 catch quotas by 80 percent. The Norwegian Ministry of Fisheries also has announced that all recreational fishing of European eels shall stop on July 1st.

The European eel (Anguilla anguilla) is listed as critically endangered in Norway and on the IUCN Red List of Threatened Species. As early as 1999, the International Council for the Exploration of the Seas (ICES) warned fishery authorities about how the European eel stock was outside safe biological limits and that the fishery was unsustainable.

”The Minister of Fisheries is making an important, and the only right choice, and is showing international leadership in fisheries management,” said WWF-Norway CEO Rasmus Hansson in a response to the new regulation. “Norway’s Fisheries Minister, Helga Pedersen, has used every occasion to point out that Norway is the best in the world on fisheries management, and by making bold moves like this they have probably earned the title.”

WWF now hopes that the Norwegian decision will influence the European Union and its member states to do their part in protecting the European eel. As of today, eel fishing is allowed within the EU despite the grave condition of the European stock.

Most IWC* member countries accidently kill whales, e.g. by unintentionally ramming into them with motorized vessels or by using fishing methods that may entangle and suffocate these air-breathing mammals as accidental by-catch. While this type of accidental deaths is reported from most member nations, Japan and South Korea have an inordinate amount of accidental by-catchs, says Professor Scott Baker, associate director of the Marine Mammal Institute at Oregon State University.

By analysing the DNA of whale-meat products sold in Japanese markets, Baker, a cetacean expert, and Dr Vimoksalehi Lukoscheck of the University of California-Irvine, found that meat from as many as 150 whales came from the coastal population. Japan’s scientific whaling program only targets whales from open ocean populations, but whales accidently killed outside the program are allowed to be sold.

Humpback Whale

Japan and South Korea are the only countries that allow the commercial sale of products derived from whales killed as accidental by-catch and the sheer number of whales represented by whale-meat products on the market suggests that there might be something fishy about these allegedly accidental kills.

They DNA study showed that nearly 46 percent of examined Minke whale products came from a coastal whale population, which has distinct genetic characteristics, and is protected by international agreements. In addition to minke whales, Baker and Lukoscheck also found DNA from Humpback whales, Bryde’s whales, Fin whales, and Western gray whales.

“The sale of bycatch alone supports a lucrative trade in whale meat at markets in some Korean coastal cities, where the wholesale price of an adult minke whale can reach as high as $100,000,” Baker said. “Given these financial incentives, you have to wonder how many of these whales are, in fact, killed intentionally.”

In January 2008, Korean police launched an investigation into organized illegal whaling in the port town of Ulsan, reportedly seizing 50 tons of minke whale meat.

Japan has asked the IWC, who is holding its annual meeting this week, to allow a small coastal whaling program in Japanese waters. This request is something that professor Baker says should be scrutinized carefully because of the uncertainty of the actual catch and the need to determine appropriate population counts to sustain the distinct stocks.

Baker and Lukoscheck have presented their findings to the IWC commission and the study will also be published in a forthcoming issue of the journal Animal Conservation.

A Cape Cod company is now launching a timer that might help save dwindling populations of sea turtles from being decimated by fishing nets.

The new device is a 7-inch (18 cm) long silver cylinder capable of keeping track of how long a net has been submerged. Federal research indicates that a vast majority of entangled sea turtles will survive if they are rescued and given a chance to breath within 50 minutes.

As soon as the device reaches a depth of at least two metres, it will start recording water depth every 30 seconds and it will also make note of any time-limit breaches. Since the honour system might not be enough, the timer has been built to save its data for later download by marine authorities.

Fishermen using the timer will not only help save the sea turtles; they may also be able to save themselves from more onerous regulations, such as no-fishing zones. The timer is naturally not a one-size fits all fix-all to the problem with turtles being drowned in fishing nets, but it might prove useful for certain types of nets in certain conditions.

The logger was built under a $25,000 federal contract with the National Oceanic and Atmospheric Administration by Onset Computer Corp., a Bourne-based supplier of data loggers for energy and environmental monitoring.

A study proposing a ban on spear guns and gill nets in the Great Barrier Reef is now being criticised by Australian scientists saying its results – which were obtained from Kenya and Papua New Guinea – aren’t relevant to the Great Barrier Reef.

The study, carried out by an international team of scientists led by Dr Josh Cinner from the ARC Centre of Excellence for Coral Reef Studies, proposed a ban on fishing gear such as spear guns, fish traps, beach seine nets, and gill nets to aid damaged reefs in their recovery. According to data obtained from the waters of Kenya and Papua New Guinea, certain types of fishing gear are more damaging to corals and to certain species of fish needed to help reefs recover from bleaching or storm damage.

“They [corals and certain types of reef fish] are already on the edge because of the overfishing and the additional impact caused by a bleaching even can push them over,” said Dr Cinner, who is based at James Cook University.

According to Dr Josh, spear guns are the most damaging of all fishing gear, particularly to fish that help maintaining the reef by removing seaweeds and sea urchins.

“Spear guns target a high proportion of species that help maintain the resilience of coral reefs, but also can result in a surprising amount of damage to the corals themselves,” Dr Cinner said. “When a fish is shot with a spear gun, it often hides in the reef, so some fishermen break the corals in their attempts to get it.”

Not applicable to the Great Barrier Reef, says other scientists Fellow JCU fisheries scientist Dr Andrew Tobin do not agree with the fishing gear ban recommendation, saying that the results from the study aren’t applicable to Australia’s Great Barrier Reef.

“Some of those findings are probably very reasonable for those areas they’ve studied, but to make any link to Great Barrier Reef waters is probably drawing a very long sword,” Dr Tobin said.

According to Townsville marine biologist Dr Walter Starck, who provides advice to Sunfish North  Queensland, herbivore fish aren’t being overfished in the Great Barrier Reef area.

“Here in Australia, it is completely irrelevant,” he said.

The work towards replenishing depleted stocks of wild sea cucumber with captive hatched ones is moving forward at a steady pace; two Philippine hatcheries has now successfully managed to hatch sea cucumbers outside their natural habitat and one batch, comprised of roughly 2,000 juveniles, has been released inside sea pens in the Philippines.

The sea cucumbers, a broad range of species belonging to the family Stichopodidae, are currently facing both overharvesting and habitat destruction in the wild, and the two Philipine hatcheries are both part of a research project carried out by the University of the Philippines Mindanao (UPM); a project aiming to mitigate the problem of overharvesting through sea

farming.

The first hatchery is a 6,000-square-meter laboratory located within a Barangay Binugay resort owned by the JV Ayala Group of Companies, while other one is situated inside Alson’s, an intensive tilapia operator.

The Barangay Binugay laboratory does not have any breeding stock; instead it collects the eggs from wild sea cucumbers, place them in a tank and fertilize them using drops of sperm – a method inspired by a Vietnamese sandfish sea cucumber hatchery and grow-out facility in tilapia .

The first Philippine batch of tiny cucumbers, each weighing no more than three grams, has now been released inside sea pens near the Barangay Binugay laboratory. Carefully, each individual cucumber was buried just below the surface of the soft sea bottom inside 78-square-meter Australian-designed sea pens.

With a history dating back to at least the Sultanate days in Mindanao, sea cucumber trading is a time honoured tradition as well as an important source of income for the Philippines. The country is currently the second largest exporter of beche-de-mer (dried sea cucumber) in the world, second only to neighbouring Indonesia, and diminishing cucumber populations are threatening the livelihood of countless families.

Beche-de-mer is currently priced at roughly 4,500 Philippine pesos per kilogram (roughly 94 USD/kg), and since large specimens are becoming increasingly rare purchasers are no longer very discerning when it comes to size. Even small cucumbers that should have been left to mature can now be sold to unscrupulous purchasers.

Did you know…..?

… that sea cucumbers are known as the earth-worms of the sea since they recycle detritus and burrow under the sand? These animals carry out an essential ecological task as they continuously shift and mix the sea bead and if they were to disappear it would have serious consequences.

… that at depths below 8.8 km (5.5 miles), sea cucumbers comprise 90% of the total mass of the macro fauna?

… that sea cucumbers aren’t appreciated as food only; some people believe them to be effective against arthritis and high blood pressure?

…that sea cucumbers have been observed engaging in mass-spawnings triggered by the moon? One species is for instance known to spawn three nights after the full moon, while two other species have been seen spawning three nights after the first quarter moon.

… that sea cucumbers have been traditionally used as an aphrodisiac and that some people still use them for this purpose today?

…that large sea cucumbers often are harvested by so called hookah diving, where divers breathe through long tubes connected to an oxygen compressor aboard a boat instead of using normal scuba tanks.

Indonesia is getting ready to sink foreign boats carrying out illegal fishing in Indonesian waters.

“We are glad the House`s Commission IV supports us in this,” Marine Resources and Fisheries Minister Freddy Numbery said at a meeting with the House commission this week.

Numbery says firm action is needed to deter foreign boats from continuing to poach, and that his office and the parliament were currently revising the law on marine resources with regard to dealing with crimes in the seas.

Elviana, a member of Commission IV, agreed with the minister and said that firm actions needed to be implemented immediately to deter foreign parties intending to steal fish from Indonesian waters.

“Tuna fish sells well so that many foreign fishermen are venturing into the country’s waters“, she said. “This must not be allowed to continue.”

Earlier, Indonesian authorities have seized illegal fishing boats and auctioned them out, but this system seems to have been ineffective.

“It is believed auctions have been arranged to ensure that the boats can be sold to their owners who are also the suspects,” Elviana said, adding that illegal boats such as from Thailand still continued operating in a great number.
