MANGALORE May 23: Excessive fishing in the coastal region has resulted in the extinction of fish species such as catfish, according to director of the Kochi-based Centre for Marine Fisheries Research Institute (CMFRI) N.G.K. Pillai.

Mr. Pillai, who was here to participate in a seminar, told The Hindu that a few species, including catfish, had already disappeared from the seas, and many species of fish were on the threshold of “sustainable-level”. He said that about 15 years ago, Karnatakas coastal belt was known for catfish. “Although it is now found in the coasts of other States, including Kerala, it is not available in this region. There were two species of catfish in this region and both of them have disappeared,” he said.

Stating that excessive fishing had affected marine biodiversity, Mr. Pillai called for urgent measures to prevent further damage to the fish species.
Export declines

Mr. Pillai said export of marine products, in terms of quantity, was declining. Indian exporters were, on the one hand, not able to meet the norms laid down by importers in countries such as the U.S. in some cases and, on the other, they had to cope with competitors in Vietnam, China and Thailand, among others. These countries had taken up aquaculture in a big way, he added.

Besides, the Indian fishing industry should re-invent itself by diversifying and adding value to the products. It could produce and market the ready-to-cook or ready-to-eat kind of products. “Everyone is looking for such products, nowadays,” he said. Indian aqua culturists, whose exports stood at about 1.3 lakh tonnes a year, were facing the problem of disease and they were not able control it. Production cost of aquaculture products was higher in India than in countries such as Vietnam, Thailand and Indonesia, he said.
New species

These countries cultivated a new species, “Vanemi”, which was easier to grow and resistant to diseases. There has been a demand to import this variety to try it out in India. That was yet to happen. Import of the species may lead to higher yield. Indian aquaculture industry was grew another species, “Tiger prawn” and “Vanemi” was an exotic species, Mr. Pillai said.

He said that he had instructed the scientists at Mangalore Research Centre of CMFRI to organise monthly interactions with fishermen and their leaders in villages so that they could identify new areas of research. On the complaints that research data of the centre were not easily accessible for public, Mr. Pillai said steps were being taken to address this issue.

Mr. Pillai inaugurated the seminar on “Biodiversity”, organised by the Mangalore Research Centre.

EMILY BEAMENT - THE SCOTSMAN

For years European Union fishermen have seen a reduction in their fishing quotas. This is meant to keep the maritime species from dying out. Recently the situation has seen a slight improvement and the numbers of some species in European waters are stabilising. On Wednesday, the EU’s Executive Committee announced its recommended quotas for next year. The quotas will again be lowered and fewer fish will be caught than in previous years. The European fishing quotas are determined on the basis of advice given by various experts, including Dutch biologists, and the IMARES research institute which specialises in marine ecology research.

Two biologists are on their hands and knees on the deck of a ship sailing the Wadden Sea. They are searching for fish such as plaice, sole, whiting, crabs and shrimp – sometimes they even find a jellyfish. The boats fish at different spots during the day. According to Marcel de Vries of IMARES:

“Each year we fish at 130 fixed locations. We return every year and we compare what we find and what we caught in previous years.”

At every spot an enormous fishing net splashes into the sea, where it remains for 15 minutes. Sometimes the net is full of junk; other times it is teeming with fish.

Plaice and sole
Plaice and sole are the most important species in the Dutch fishing trade, which is why the study placed special emphasis on the two flatfish. Biologist Loes Bolle says the fishing expeditions are only a minor part of the extensive research which determines European Union advisory policies.

“We count fish in all Dutch waters, but the same happens in Germany, Belgium, England and Denmark. We also estimate how many fish are caught by fishermen. We combine the statistics in an attempt to determine how many fish can be caught without threatening the species’ survival.”

After the fish are counted on the Wadden Sea, each one is measured to determine the proportion of smaller and younger fish, or young and old.

Thankless task
In the course of the day the scientists spend many hours on their knees, counting and measuring hundreds of plaice and sole. But the work seems thankless, since the politicians will probably ignore their advice. Biologist Loes Bolle says they are more concerned about protecting the economic interests of the fishing industry, which means they’ll often allow an increase in the quotas.

“We give biologically responsible advice, in other words, we do our best to recommend how fish can be caught in a sustainable manner. We are attempting to help fishermen keep the population at a viable level so that the species can survive. The best course of action would be to ban fishing for the time being, but that is not realistic. We do our best to ensure that enough fish will survive so that the species do not become extinct. This will also guarantee that fishing does not become extinct.”

Biologists are recommending a reduction in the quota for plaice and sole in 2008. It’s now the politicians’ turn, beginning with the European Commission.

Cambridge, United Kingdom (AHN) - Wildlife protection group WWF on Thursday said the bigeye tuna is on the brink of extinction because of excessive fishing.

The bigeye tuna, which is used to make sashimi and sushi, is one of the most common types of tuna popular in Japan, a country that consumes a quarter of the world’s supply of the fish.

A WWF statement read, “Bigeye tuna are under threat because authorities are failing to recognize the dire extent of overfishing.”

The group said in order to arrest the chilling trend, authorities in tuna-fishing countries should set a limit on the catch and set programs to restore the population of the bigeye tuna.

TRAFFIC, a monitoring group of the WWF and the IUCN-The World Conservation Union, said catching young or juvenile bigeye tuna reduces the availability of adults and compromises the stock because nothing will be breeding new young.

Glenn Sant, TRAFFIC’s Global Marine Program head, said “Instead they end up being worth a few cents in a can, and tuna stocks are on the verge of collapse. The biological and economic future of the bigeye tuna fishery is at serious risk.”

Fish and Fly

A shocking picture of over one in three freshwater fish species struggling for survival has emerged.

In a first ever assessment of European fish research shows how 100 years of industrial development has wreaked havoc on river systems.

The study done by the World Conservation Union (IUCN) and published in the Handbook of European Freshwater Fishes reveals that 200 of the 522 species are threatened with extinction - 12 are already extinct.

William Darwall, from IUCN, said: “Many of these species, not considered as ‘charismatic’ or with any apparent ‘value’ to people, rarely attract the funds needed for their conservation.

“They risk disappearing with only a dedicated few noticing the loss.”

He went on to say that many of the species could be saved just by simple water purification and flood control.

Examples of fish most in danger include the European eel (Anguilla anguilla), Gizani (Ladigesocypis ghigii) and Jarabugo (Anaecypis hispanica).

Leading Northwest scientists and orca advocates are urging NOAA Fisheries to consider removal of the four lower Snake River dams in order to protect endangered Puget Sound orca populations that need Columbia-Snake River salmon as a critical food source.

“Restoring Columbia River Chinook salmon is the single most important thing we can do to ensure the future survival of the Southern Resident Community of killer whales,” said Dr. Rich Osborne, research associate with The Whale Museum in Friday Harbor, WA. “We cannot hope to restore the killer whale population without also restoring the salmon upon which these whales have depended for thousands of years. Their futures are intricately linked.”

The comments from the six prominent orca scientists, delivered in a letter to Northwest members of Congress and NOAA regional administrator Robert Lohn, came in response to the Oct. 31 release of a new draft Biological Opinion from NOAA Fisheries for Columbia-Snake River salmon management. Salmon advocates say the new plan, the result of a court-ordered rewrite of an earlier, illegal 2004 federal salmon plan, fails to do enough to recover imperiled salmon in the seven-state Columbia-Snake river basin, and ignores altogether the four dams on the lower Snake River that do the most harm to these fish.

“History will not be very forgiving of the resource managers who failed in their responsibilities to these icons of the Pacific Northwest, Chinook and orca,” said Ken Balcomb, senior scientist with the Center for Whale Research.

“The draft plan relies heavily on actions that science and time have proven will not restore these fish to the levels necessary for self-sustaining populations of salmon, or abundant enough to provide a healthy food resource for these killers whales,” said Dr. David Bain, a killer whale biologist at Friday Harbor Labs. “Not only are salmon from the Columbia River an important historic food source, recovered abundant salmon in this river are an indispensable requirement for the future recovery of Southern Residents.”

“The new Federal salmon plan for the Columbia and Snake rivers is no better than previous plans in providing access to the basin’s best remaining salmon habitat in the upper reaches of the Snake River,” said Howard Garrett, co-founder of the Orca Network. “The resulting declining salmon runs have a very real impact on the 88 endangered southern resident orcas that depend on these fish, as they have for centuries. As the salmon disappear, the orcas go hungry.”

“The best science tells us,” Garrett added, “that to revitalize Snake River salmon, we’ll need to bypass the dams that block fish passage, and that dam removal, combined with a variety of economic investments, will bring benefits to upriver communities in eastern Washington as well as to Puget Sound.”

The Columbia and Snake River Basin was once the world’s most productive salmon watershed, with tens of millions of fish returning annually. Today, returns hover near 1% of those historic levels. More than 200 large dams on the basin’s rivers are the major cause of this crisis, with 13 populations now listed under the Endangered Species Act, and four directly impacted by the lower Snake River dams. Yet, the Columbia-Snake Basin still holds more acres of pristine salmon habitat than any watershed in the lower 48 states.

It is this opportunity, notes Kathy Fletcher, executive director of People For Puget Sound, that we must take advantage of, if we hope to protect and restore these two iconic Northwest species whose fates are inexorably intertwined.

“Our leaders must look for solutions not only in Puget Sound, but also in the rivers that bring the salmon to the sea throughout the Northwest,” Fletcher said. “The great salmon rivers like the Columbia and Snake can once again produce the healthy runs of Chinook, on which our majestic orcas feed, but only if we recover salmon habitat. We must act quickly to restore clean water, abundant, sustainable salmon populations, and a safe home for orcas. The scientists tell us there is no time to waste.”

SCOTLAND’S world-famous “queen” of salmon rivers is being fished to extinction, according to its ghillies, who are pleading with its fisheries board to implement new laws to save its depleted fish stocks.

Anglers from across the world have flocked to Perthshire for decades to fish for Atlantic salmon in Scotland’s longest and most renowned river, the Tay.

But the Tay Ghillies Association has revealed it has been “a dreadfully poor salmon fishing season”, with catches down by 50 per cent and expected to fall even further next season. The association accuses the Tay District Salmon Fisheries Board of ignoring a number of warning signs.

A spokesman for the Tay Ghillies Association said: “The annual catch numbers on the River Tay this year with rod and line will not amount to any more than 6,000 fish. The Dee, which is a fraction of the size of the Tay, with a fraction of the anglers, are set to do 5,000.”

However, David Summers, of the Tay District Salmon Fisheries Board, said: “The idea that the Tay has completely collapsed is grossly overblown.”

He said the policy of catch-and-release needed strengthening, adding: “For next season we are advocating that, in the spring, you must put back the first fish every day and you may keep the next one.

“We currently ask that anglers not fish with worms before the end of May and certainly not in September and October. However, we are reviewing this policy.”

In Scotland, 85,901 salmon were reported caught in 2006, with 47,471 - 55 per cent of the total catch - being released.

Seven-year battle to implement previously achieved protections continues in Court

Sacramento - On November 13th, the California Court of Appeal will hear the case of California Forestry Association et al. v. Fish & Game Commission et al. to decide the future of California’s embattled Coho salmon. The original petition for listing the Coho under the California Endangered Species Act (CESA) was successfully submitted by California Trout on behalf of the Salmon and Steelhead Recovery Coalition in July 2000. A consortium of timber interests has repeatedly challenged the listing, forcing it to ever-higher levels of the court system in attempts to avoid implementing state recommended protective measures for Coho salmon designed to recover the species.

“It’s time to put and end to this legal battle and to start conserving Coho salmon and their habitats,” said Brian Stranko of California Trout. “No endangered species should have to wait seven years to receive effective protection. The California Forestry Association is pursuing a course that imperils the natural heritage of our state.”

California’s Coho salmon received full protection under a finalized CESA listing in March 2005, but the ongoing legal challenges are attempts to undo years of recovery planning and block efforts to improve conditions required for species survival. The Coho advocates’ position has been upheld at every level of decision-making including the current ruling by the state superior court in June 2006. The Coho are also listed under the federal Endangered Species Act but the federal government has not completed recovery plans, failing to provide the practical recovery actions needed to aid population recovery.

Coho habitat has been severely degraded over the past century, largely due to poor land use practices that have resulted in rising water temperatures, increased river siltation, low water flows and a lack of habitat complexity in historic Coho streams. As a consequence, the Coho salmon population has been reduced by over 90% in California, with many stream populations wiped out entirely. If the state endangered listing were to be overturned or its provisions weakened, the Coho could lose its best chance of survival.

California Trout has intervened in this case as part of their ongoing work to protect the wild native fish species of California, an effort which over the last four decades has resulted in significant conservation improvements throughout the state.

A decision in the current appeal is expected in early 2008.

About California Trout: Founded in 1971, California Trout was the first statewide conservation group to focus on securing protections for California’s unparalleled wild and native trout diversity. Working with local communities, business, partners and government agencies, California Trout employs conservation science, education, and advocacy to craft effective solutions for California’s water resources and fisheries. Among its many current initiatives, California Trout is now leading the effort to save the official state fish, which is the California golden trout.

A number of species of marine creatures could become extinct in the seas of south-east Asia in the near future as a result over-fishing, a new report has warned.

Meryl Williams produced a report on the issue for the Australian Lowy Institute.

She found that Indonesia, Thailand, Vietnam and the Philippines have recently expanded their fishing operations significantly and the increased activity is putting extreme pressure on stocks.

Ms Williams explained to Reuters: “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.

In addition, Ms Williams said that more needed to be done to tackle problems with illegal fishing operations.

Recently, a report from the World Conservation Union (IUCN) suggested that a third of freshwater fish in Europe are at serious risk of becoming extinct.

Daily Telegraph (AU) WILDLIFE conservation groups have blasted Japan over its failure to prevent overfishing of the southern bluefin tuna, driving the species closer to extinction.

Conservation groups say an international commission’s failure to prevent overfishing of the southern bluefin tuna is driving the species closer to extinction.Wildlife trade-monitoring network Traffic and conservation body WWF said today the Commission for the Conservation of Southern Bluefin Tuna’s (CCSBT) annual meeting in Canberra at the weekend made no significant progress in preventing the overharvesting of the internationally popular table fish.

“The meeting became embroiled in discussions that went round and round in circles getting nowhere, Traffic spokesman Glenn Sant said in a statement.

“The southern bluefin tuna stock is at historically-low levels with less than 10 per cent of the virgin stock left.

“Reviews conducted by the commission have shown massive over-catch by a member, yet Japan has continued to ensure that any finger pointing to those responsible is locked up in confidentiality.”

Traffic said overfishing was driving the species further towards extinction.

WWF spokeswoman Lorraine Hitch said the commission also failed to agree on anything related to minimising bycatch of albatrosses, petrels, sharks and marine turtles.

“They were unable to agree on even the most fundamental aspects of bycatch management such as data collection,” she said.

The Humane Society International estimates 13,500 seabirds die every year on longline fishing vessels targeting southern bluefin tuna and 10,000 of them were species of albatross.
