The UK trawl fishing fleet has to work 17 times harder to catch the same amount of fish today as it did when most of its boats were powered by sail, according to new research. Researchers from the University of York and the Marine Conservation Society (MCS) used UK Government data on the amount of fish caught and the size and number of boats involved "“ the fleet's fishing power "“ to analyze the change in fish stocks since 1889. They found that trawl fish landings peaked in...

Model Could be Used to Forecast Climate Impacts for Other Fisheries A new climate-population model developed by NOAA scientists to study rising ocean temperatures and fishing rates on one East Coast fish population could also forecast the impact of climate change and fishing on other fisheries. The model is one of the first to directly link a specific fish stock with climate change. In a paper in the March 2010 issue of the journal Ecology Applications published online March 24 by the...

Efforts to curb overfishing throughout the world are beginning to succeed in five of the world's ten large marine ecosystems, according to a comprehensive study published Thursday. The new research comes just two years after a study that warned that overfishing could cause a collapse in the world's seafood stocks by 2048. "This paper shows that our oceans are not a lost cause," said Boris Worm of Dalhousie University in Halifax, Nova Scotia. "I'm somewhat more hopeful ... than what we were...

Scientists have joined forces in a groundbreaking assessment on the status of marine fisheries and ecosystems.The two-year study, led by Boris Worm of Dalhousie University and Ray Hilborn of the University of Washington and including an international team of 19 co-authors, shows that steps taken to curb overfishing are beginning to succeed in five of the 10 large marine ecosystems that they examined.The paper, which appears in the July 31 issue of the journal Science, provides new hope for...

By Kirk Moore, Asbury Park Press, N.J. Aug. 6--A scientific reappraisal of the East Coast summer flounder stock shows the flatfish population is much closer to a full recovery than previously thought, a finding that could allow the Mid-Atlantic Fishery Management Council to move today toward allowing a modest increase in fishermen's catches for 2009. "This is the first time in years that overfishing is not occurring," said scientist James Weinberg of the federal fisheries science...

2 dolphin stocks may be recovering from tuna fishing practicesThe numbers of Northeastern offshore spotted and eastern spinner dolphins in the eastern tropical Pacific Ocean are increasing after being severely depleted because of accidental death in the tuna purse-seine fishery between 1960 and 1990, according to biologists from NOAA's Fisheries Service."These estimates are encouraging because they are consistent with what we would expect to see if these stocks are recovering, now that...

Fishery biologist Sandy Sutherland looks through the lens of the microscope at tiny sections of fish earbones, known as otoliths, each showing annual bands of growth. She carefully counts the bands to determine the age of the fish, then moves on to the next sample.  Known as an age reader, Sutherland is one of a small team at NOAA's Northeast Fisheries Science Center (NEFSC) whose aging work is critical to stock assessments needed to manage the nation's fishery resources in the Northwest...

Giant bluefin tuna are in trouble, primarily because the powerful muscles that propel their extensive ocean migrations come with an Achilles' heel: They're tasty. Prized by sushi lovers for their savory succulence and by fishermen for the incomparable price they command - one 607-pound fish fetched over $90 per pound at a January auction in Tokyo - all three species of bluefins have seen their population plummet in the past 50 years thanks to worldwide demand. However, there is hope for...

NEW ORLEANS (AP) -- Federal regulators have done too little to save the overfished red snapper in the Gulf of Mexico, a new lawsuit by environmental groups alleges. "It's a classic case of fiddling while Rome burns," said Aaron Viles, fisheries campaign director for the Gulf Restoration Network, which filed the lawsuit along with the Ocean Conservancy. The federal lawsuit filed Friday asks a federal judge to order the National Marine Fisheries Service, or NMFS, to implement stricter...
