The competition between farmers and fish for precious water in California is intensifying in wine country, suggests a new study by biologists at the University of California, Berkeley. The findings, published in the May issue of the journal Transactions of the American Fisheries Society, link higher death rates for threatened juvenile steelhead trout with low water levels in the summer and the amount of vineyard acreage upstream. The researchers found that juvenile steelhead trout are...

Projected Harvest Demonstrates Ongoing Success of Responsible Fisheries Management, according to the Alaska Seafood Marketing Institute. Anchorage, AK (PRWEB) May 11, 2012 The summer season for wild Alaska salmon has officially opened with a projected harvest of 132 million fish. Should the actual harvest match or exceed this figure, 2012 will mark the 25th consecutive year of a harvest in excess of 100 million salmon. While initial openings are amongst the lower volume troll-caught salmon...

New research suggests that allowing more Pacific salmon to spawn in coastal streams will not only benefit the natural environment, including grizzly bears, but could also lead to more salmon in the ocean and thus larger salmon harvests in the long term–a win-win for ecosystems and humans. In a new article and accompanying synopsis published April 10 in the online, open-access journal PLoS Biology, Taal Levi and co-authors from UC Santa Cruz and Canada investigate how increasing...

Study finds most Chinook salmon spawning in Mokelumne River were hatchery raised Scientists have found that only about ten percent of the fall-run Chinook salmon spawning in California's Mokelumne River are naturally produced wild salmon. A massive influx of hatchery-raised fish that return to spawn in the wild is masking the fact that too few wild fish are returning to sustain a natural population in the river. The study, published in the online journal PLoS ONE, highlights the danger...

Hatcheries Change Salmon Genetics After A Single Generation
2011-12-20 10:28:33

The impact of hatcheries on salmon is so profound that in just one generation traits are selected that allow fish to survive and prosper in the hatchery environment, at the cost of their ability to thrive and reproduce in a wild environment. These findings, published this week in Proceedings of the National Academy of Sciences, show a speed of evolution and natural selection that surprised researchers. They confirmed that a primary impact of hatcheries is a change in fish genetics, as...

Stocks of  Atlantic salmon (Salmo salar), which have been steadily declining for the past few decades, are facing  new challenges in the Gulf of Maine, where changing spring wind patterns, warming sea surface temperatures and new predators along altered migration routes are affecting their survival. In a paper published online in the journal Fisheries Management and Ecology, Kevin Friedland and co-authors suggest post-smolts are entering an increasingly warmer coastal ocean,...

PORTLAND, Ore., Aug. 9, 2011 /PRNewswire-USNewswire/ -- Over 1,000 American businesses have asked President Obama for decisive change in the government's failed policy to restore endangered wild salmon and steelhead in the Columbia and Snake Rivers. The request comes in a letter released today, following U.S. District Judge James Redden ruling on August 2, 2011 finding the administration's current salmon plan illegal. Salmon are a mainstay of economies and jobs for the entire west coast....

Fishing, conservation groups call for solutions table on salmon crisis PORTLAND, Ore., Aug. 2, 2011 /PRNewswire-USNewswire/ -- U.S. District Court Judge James Redden ruled today that the National Oceanic and Atmospheric Administration (NOAA) Fisheries Service failed for the third time in ten years to produce a legal and scientifically adequate plan to protect imperiled Columbia-Snake River salmon from extinction. The harm to these species has been largely caused by operation of the...

CORDOVA, Alaska, April 5, 2011 /PRNewswire/ -- Prince William Sound Aquaculture Corporation [PWSAC] recently released findings from an economic report that examines the impact of its hatchery program on the pink salmon market. PWSAC played a critical role in the recent economic recovery of the Alaska salmon industry. Since 2006, PWSAC has produced one in four of Alaska's commercially caught pink salmon. Large harvests of PWSAC pinks have provided the industry with the volume and...

CORDOVA, Alaska, Sept. 30 /PRNewswire/ -- The Prince William Sound Aquaculture Corporation [PWSAC] today released findings from an economic study that confirms a long-held suspicion: hatchery fish are critical to the sustainability and health of Alaska's commercial salmon fishery, the sport fishery and to regional and statewide economies. Cordova-based PWSAC operates five hatcheries in the Prince William Sound/Copper River region, all of which generate millions of pink, chum, Coho and...
