A Japanese salmon species thought to be extinct for 70 years is alive and well in a lake near Mount Fuji, a science professor said Wednesday. http://phys.org/news211608681.html Biology Wed, 15 Dec 2010 04:11:59 EST news211608681 A new UC Davis study contradicts earlier reports that salmon farms were responsible for the 2002 population crash of wild pink salmon in the Broughton Archipelago of western Canada. http://phys.org/news211476719.html Biology Mon, 13 Dec 2010 15:50:08 EST news211476719 With the number of salmon in the North Pacific having doubled in the past 50 years, scientists are increasingly concerned there may not be enough food to support them, and changing ocean conditions could make it even worse. http://phys.org/news210178810.html Biology Sun, 28 Nov 2010 15:00:31 EST news210178810 The review process being used by the Food and Drug Administration to assess the safety of a faster-growing transgenic salmon fails to weigh the full effects of the fish's widespread production, according to analysis by a Duke University-led team in this week's Science. http://phys.org/news209312912.html Space & Earth Thu, 18 Nov 2010 14:28:44 EST news209312912 You would never confuse Seattle, Washington, with New York City. One is home to about 600,000 people, the other has a population of 8.2 million. One ardently protects the wild salmon thrashing through its rivers, the other likes its salmon smoked and served with cream cheese on a bagel. But these cities share an important feature: They're both leaders in addressing the issue of climate change, and both rely on space-based data to help them make their plans. http://phys.org/news209302500.html Space & Earth Thu, 18 Nov 2010 11:36:23 EST news209302500 Salmon farms are transferring parasitic sea lice to wild salmon over a much wider region than first thought. That’s the conclusion of a newly published article called Evidence of farm-induced parasite infestations on wild juvenile salmon in multiple regions of coastal British Columbia, Canada. http://phys.org/news208534085.html Biology Tue, 09 Nov 2010 14:08:44 EST news208534085 Scientists with the U.S. Department of Agriculture (USDA) are helping ensure that the smoked salmon that's always a hit at festive gatherings also is always safe to eat, including among their achievements the development of a first-of-its-kind mathematical model that food processors and others can use to select the optimal combination of temperature and concentrations of salt and smoke compounds to reduce or eliminate microbial contamination of the product. http://phys.org/news207328601.html Biology Tue, 26 Oct 2010 16:16:57 EST news207328601 Everyone knows that sharks have an amazing sense of smell.
