Finding alternative feed sources for chickens, pigs and other farm animals will significantly reduce pressure on the world's dwindling fisheries while contributing positively to climate change, according to University of British Columbia researchers. http://www.physorg.com/news177682614.html Biology Tue, 17 Nov 2009 12:17:35 EST news177682614 An Australian method for assessing the environmental impact of marine fisheries has caught the eye of fishery management agencies worldwide. http://www.physorg.com/news175867400.html Biology Tue, 27 Oct 2009 13:20:01 EST news175867400 Among the many changes in the ocean is the expansion of oxygen-deficient or oxygen minimum zones (OMZs), also known as dead zones, which affect the processes by which carbon is captured and sequestered on the seafloor and alter the microbial activities that impact the rate and magnitude of ocean carbon sequestration. Despite the importance of these effects, very little is known about the metabolism of OMZ microbes and how they respond to environmental changes. http://www.physorg.com/news175439852.html Space & Earth Thu, 22 Oct 2009 14:18:14 EST news175439852 Years before an economic crisis taught everyone the risks of runaway growth, marine fishermen and fishery managers were already getting a crash course. http://www.physorg.com/news174594185.html Biology Mon, 12 Oct 2009 20:00:02 EST news174594185 Aquaculture, once a fledgling industry, now accounts for 50 percent of the fish consumed globally, according to a new report by an international team of researchers. And while the industry is more efficient than ever, it is also putting a significant strain on marine resources by consuming large amounts of feed made from wild fish harvested from the sea, the authors conclude. Their findings are published in the Sept. 7 online edition of the Proceedings of the National Academy of Sciences (PNAS). http://www.physorg.com/news171564523.html Biology Mon, 07 Sep 2009 17:49:39 EST news171564523 (PhysOrg.com) -- Scientists are set to study the earbones and organs of more than 2000 albacore tuna to better understand the growth, age and breeding patterns of this increasingly important species. http://www.physorg.com/news169218695.html Biology Tue, 11 Aug 2009 14:40:01 EST news169218695 (AP) -- Yukon River smokehouses should be filled this summer with oil-rich strips of king salmon - long used by Alaska Natives as a high-energy food to get through the long Alaska winters. But they're mostly empty. http://www.physorg.com/news168442502.html Biology Sun, 02 Aug 2009 14:50:01 EST news168442502 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 ten large marine ecosystems that they examined. The paper, which appears in the July 31 issue of the journal Science, provides new hope for rebuilding troubled fisheries. http://www.physorg.com/news168183004.html Space & Earth Thu, 30 Jul 2009 14:32:54 EST news168183004 A reduction of as little as five per cent in fisheries catch could result in as much as 30 per cent of the British Columbia coastal ecosystems being protected from overfishing, according to a new study from the UBC Fisheries Centre. http://www.physorg.com/news167476630.html Space & Earth Wed, 22 Jul 2009 10:18:49 EST news167476630 (PhysOrg.com) -- The Great Lakes are in the midst of a remarkable ecological transformation, driven largely by the blitzkrieg advance of two closely related species of non-native mussels. http://www.physorg.com/news166978895.html Space & Earth Thu, 16 Jul 2009 16:40:04 EST news166978895 According to the most recent report on the status of the world's fisheries by the United Nations Food and Agriculture Organization, fisheries supply at least 15% of the animal protein consumed by humans, provide direct and indirect employment for nearly 200 million people worldwide and generate $US85 billion annually. This same report indicates that 28% of the world's fisheries stocks are currently being overexploited or have collapsed and 52% are fully exploited. http://www.physorg.com/news164962399.html Biology Tue, 23 Jun 2009 07:54:15 EST news164962399 hanges in ocean chemistry -- a consequence of increased carbon dioxide (CO2) emissions from human industrial activity - could cause U.S. shellfish revenues to drop significantly in the next 50 years, according to a new study by researchers at the Woods Hole Oceanographic Institution. http://www.physorg.com/news164455043.html Space & Earth Wed, 17 Jun 2009 11:20:03 EST news164455043 (AP) -- Federal fisheries regulators on Thursday released a court-ordered plan to help struggling chinook salmon that includes opening California dams and restricting pumping, which would reduce the amount of water available to farms and urban areas. http://www.physorg.com/news163360026.html Space & Earth Thu, 04 Jun 2009 18:47:37 EST news163360026 Weak enforcement combined with fishermen facing serious economic hardships are leading to widespread violations of fisheries regulations along the Northeastern United States coast. This pattern of noncompliance threatens the success of new fisheries management measures put in place to protect and restore fish stocks, according to a new study published online this week in the journal Marine Policy. http://www.physorg.com/news163343801.html Biology Thu, 04 Jun 2009 14:17:21 EST news163343801 The Atlantic cod has, for many centuries, sustained major fisheries on both sides of the Atlantic. However, the North American fisheries have now largely collapsed. A new paper in the open-access, peer-reviewed journal PLoS ONE from scientists at the University of Iceland and Marine Research Institute in Reykjavik provides insights into possible mechanisms of the collapse of fisheries, due to fisheries-induced evolution. http://www.physorg.com/news162625581.html Biology Wed, 27 May 2009 06:46:53 EST news162625581 The Wildlife Conservation Society announced today a study showing that some coral reefs off East Africa are unusually resilient to climate change due to improved fisheries management and a combination of geophysical factors. WCS announced the results of the study at the International Coral Reef Initiative (ICRI), which is meeting this week in Phuket, Thailand. http://www.physorg.com/news159705106.html Space & Earth Thu, 23 Apr 2009 11:32:14 EST news159705106 (PhysOrg.com) -- New England lobstermen have gone high tech by adding low-cost instruments to their lobster pots that record bottom temperature and provide data that could help improve ocean circulation models in the Gulf of Maine. http://www.physorg.com/news155818404.html Space & Earth Mon, 09 Mar 2009 11:54:16 EST news155818404 (PhysOrg.com) -- For decades there has been a controversy about whales eating fish in the tropics. The `whales eat fish` debate has been at the heart of policy decisions about the culling of whales and is pivotal to the future of commercial whaling in the region. Today, however, chalk one up for the whales. http://www.physorg.com/news154023335.html Space & Earth Mon, 16 Feb 2009 16:17:10 EST news154023335 The economy isn't just squeezing the middle class on land, it's also affecting fish. http://www.physorg.com/news153494857.html Space & Earth Tue, 10 Feb 2009 13:28:06 EST news153494857 Federal fishery regulators Thursday approved an unprecedented plan to ban U.S. commercial fishing in the Arctic Ocean. http://www.physorg.com/news153147884.html Space & Earth Fri, 06 Feb 2009 13:05:10 EST news153147884 A new study funded by NOAA and the National Science Foundation reveals that a part of the Strait of Juan de Fuca, which separates Washington state from Canada's British Columbia, is a potential "hot spot" for toxic harmful algal blooms affecting the Washington and British Columbia coasts. Understanding where and how these blooms originate and move is critical for accurate forecasts that could provide early warning to protect human and ecosystem health, according to NOAA scientists. http://www.physorg.com/news152817414.html Space & Earth Mon, 02 Feb 2009 17:17:28 EST news152817414 A large number of North Atlantic right whales have been seen in the Gulf of Maine in recent days, leading right whale researchers at NOAA's Northeast Fisheries Science Center (NEFSC) to believe they have identified a wintering ground and potentially a breeding ground for this endangered species. http://www.physorg.com/news150115302.html Biology Fri, 02 Jan 2009 10:41:42 EST news150115302 A study published in the September 19 issue of Science shows that an innovative yet contentious fisheries management strategy called "catch shares" can reverse fisheries collapse. Where traditional "open access" fisheries have converted to catch shares, both fishermen and the oceans have benefited. http://www.physorg.com/news140965324.html Space & Earth Thu, 18 Sep 2008 14:02:04 EST news140965324 Small scale fisheries produce as much annual catch for human consumption and use less than one-eighth the fuel as their industrial counterparts, but they are dealt a double-whammy by well-intentioned eco-labelling initiatives and ill-conceived fuel subsidies, according to a University of British Columbia study. http://www.physorg.com/news138973149.html Biology Tue, 26 Aug 2008 12:39:09 EST news138973149
