Use Property Rights to Save Fisheries Around the Globe, Says New Study – Who needs Science?!

bean_counterIf nothing is done to reform open-access fisheries around the world, fishing stocks could drop by as much as 77 percent below current levels by 2050, reports a new study in the Proceedings of the National Academy of Sciences. If, however, property rights were assigned to individual fishers or communities, the yield trajectory of most of the world’s fisheries would shift sharply upward and most would recover biologically in only 10 years. These conclusions were reached by a team of researchers led by University of California, Santa Barbara environmental scientist Christopher Costello in their study, “Global fishing prospects under contrasting management regimes.” The Bean Counters.

Canadian scientists find Fukushima fallout rising off West Coast

Radioactivity from Japan’s crippled nuclear reactors has turned up off the British Columbia coast and the level will likely peak in waters off North America in the next year or two, says a Canadian-led team that’s intercepted the nuclear plume. The radioactivity “does not represent a threat to human health or the environment,” but is detectable off Canada’s west coast and is climbing, a team led by oceanographer John Smith at reported Monday in the Proceedings of the National Academy of Sciences.

New Minnesota environmental law bans triclosan

A University of Minnesota study published in January 2013 in the journal Environmental Science and Technology said increasing amounts of triclosan were found in the sediment in eight Minnesota lakes and rivers, including Lake Superior, the Duluth harbor, Shagawa Lake in Ely, Lake Pepin, Lake St. Croix, Lake Winona and East Lake Gemini, all of which receive treated sewage effluent.

Tied to rising ocean temperatures in the Bering Sea and North Pacific that spurred the growth of the prey of salmon and seabirds alike, the “much larger than previously known” impact of pink salmon is reported in a new Proceedings of the National Academy of Sciences report. Read more here  17:32

Study: Alaska salmon stocks spiked and crashed long before commercial fishing

ANCHORAGE — A new study presents evidence that salmon populations in Bristol Bay have surged and sagged wildly — for hundreds of years at a time — well before the first commercial fishing in Alaska. The research, published this month in the online edition of the Proceedings of the National Academy of Sciences, summarized data collected and analyzed over the past 15 years by scientists in the U.S., Canada, Norway and China.
