Argentine fisheries yields down a third

Mystery over dead fish in California harbor
Los Angeles (AFP) March 8, 2011 - Californian fishermen and harbor chiefs were puzzled after millions of dead anchovies were found floating in a marina just south of Los Angeles on Tuesday. Experts said the fish, found at a harbor in Redondo Beach, may have from lack of oxygen due to algae, while locals wondered if high winds overnight might have something to do with it. "It looks like what happens to goldfish when you don't change the water in the tank, mouth open and belly up," said local official Bill Workman, cited by the Los Angeles Times newspaper.

"There are no visible signs of any toxins that might have caused (the deaths) and our early assessment is that this was oxygen depletion," he said, adding: "There are no oil slicks or leaking of substances into the water." Locals at Redondo Beach, where the stench from the dead fish hung over King Harbor, suggested that high winds could have driven the fish into the harbor, where their sheer numbers would have reduced the oxygen available. Experts were cautious. "What we're trying to tease apart is whether it's a consequence of algal buildup, a fish buildup or something toxic in the water," said David Caron of the University of Southern California.

Buenos Aires (UPI) Mar 8, 2011
Argentina's fisheries yields showed a dramatic drop of almost one-third in the first two months of the year, new data from the country's fisheries and aquaculture department indicated.

Argentina is already facing low yields in grain crops due to the effects of La Nina weather phenomenon, which has led to low rainfall and drought in vast tracts of agricultural land in the Latin American country.

Officials had no immediate word on whether the yield from the country's fishing areas indicated a trend likely to continue through the coming months or a passing phase. Industry officials said the low yields would affect jobs and earnings in the fisheries sector, already under pressure from decline in Argentina's marine stock.

Landings of fish during the first two months of 2011 dropped 30.4 percent compared to a year ago and totaled 50,749 tons. The yield contrasted with 72,819 tons for the period in 2010, the Fishing Information and Services reported.

The total yield represented a mixture of marine life captured during the season and comprised 40,632 tons of fish, 5,995 tons of mollusks and 4,121 tons of crustaceans, officials said.

The highest recorded landing in the period was for hake with 16,850 tons, which is 19.1 percent less than the same period a year ago. Squid followed with 5,696 tons, 69.8 percent less than in the first two months of 2010, with 18,859 tons.

Officials expressed concerns in the past that overfishing could affect overall yields of fish and other marine animals in Argentine waters. Fishing industry lobbies have complained of lack of government incentives amid aggressive competition from foreign fishing fleets.

Landings of hoki totaled 3,160 tons, stingray 2,208 tons, haddock accounted for 1,768 tons and croaker 1,290 tons, FIS said.

The fisheries' production of squid raised alarm earlier this year after crews found the stock already low outside the country's exclusive economic zone.

Last year, major rows broke out over what authorities and conservationists called indiscriminate fishing of existing stock of marine food resources in Argentine waters and beyond, mostly in zones operated by vessels from the industry.

Critics blamed lack of good governance and transparency in the business of maintaining a balance between renewable fish stock and the crews operating in those areas for maximum profit.

The limited presence of squid at mile 201, outside Argentina's exclusive economic zone, is of concern to the local squid jigger fleet, industry sources said. Fishing crews fear that something similar might happen in national waters, the sources said in published reports.

Guillermo de los Santos, president of the Chamber for Jigger Fishing Shipowners of Argentina, blamed foreign fishing fleets. He said around 17 Chinese and 15 South Korean ships with fishing licenses from the Falkland Islands were "catching very little but, more importantly, destroying stocks of the resource."

Argentina has been campaigning for its sovereignty over the British-ruled Falkland Islands and has taken measures to discourage shipping and trade involving the Falklands. Argentina and Falklands went to war over the Falklands in 1982, with deaths of more than 1,000 fighters and civilians.

In contrast to Argentina, Chile reported a 243 percent rise in landings of giant squid. However, Chilean exporters also found themselves battling for export markets as the peso rose against the U.S. dollar, making Chilean exports overall less attractive.

Fishing in Peru is also in crisis, with crews reporting sharp fluctuations in yields.

A New Model To Measure Organic Carbon In Surface Waters
Washington DC (SPX) Mar 08, 2011
A new carbon model allows scientists to estimate sources and losses of organic carbon in surface waters in the United States. Study results indicate that streams act as both sources and sinks for organic carbon. "Model estimates help managers and researchers track carbon transport in streams, which is information that is ultimately needed to improve our understanding of the fate of rising ... read more
