Medred: If Prince William Sound is a salmon ranch, what's the problem?

Craig Medred | Dec 25, 2011

Fears of some state fisheries biologists that turning Prince William Sound into one big, salmon ranch might threaten the remaining wild stocks there gained some weight this week. Oregon researchers reported in the journal Proceedings of the National Academy of Sciences that the genes of steelhead trout -- a close relative -- appear easily altered in a hatchery.
Mark Christie, lead researcher on the work done at Oregon State University, painted a portrait of "evolution at warp speed" in the sterile, environmentally controlled trays of a hatchery.
"It's similar to the process by which wolves were transformed into dogs," he told MSNBC. "That's all that's occurring here, except it's occurring at a really rapid time scale."
Whether the 11,000-square-mile Sound -- smeared by the Exxon Valdez oil spill in 1989 -- should be home to piscatorial wolves or dogs has been a subject of debate for years now between the Alaska Department of Fish and Game and the Prince William Sound Aquaculture Association (PWSAA).
"Our obligation to manage wild (salmon) stocks in Prince William Sound is very challenged at current levels of population," state scientists warned in an April 2010 memorandum. "Department … studies suggest that at current (hatchery) production levels, hatchery salmon straying may pose an unacceptable risk to wild salmon stocks."
Essentially every wild salmon-spawning stream in the Sound has now been infiltrated by straying hatchery salmon. Contrary to popular perception, salmon don't all return to their natal streams, and pink salmon -- one of the major species ranched in the Sound -- are famous for...... http://www.alaskadispatch.com/article/if-prince-william-sound-salmon-ranch-whats-problem

Crabbers get a boost in bairdi Tanner quotas

LAINE WELCH Image via Wikipedia FISHERIES Published: November 7th, 2009 10:10 PM Last Modified: November 7th, 2009 10:12 PM KODIAK -- Kodiak and Alaska Peninsula crabbers got some good news last week -- bigger catch quotas for bairdi Tanner crab, a mid-January fishery important to local economies. Bairdi are the larger cousins of the better-known opilio Tanners, or snow crab. The bairdi boost stems from a big pulse of new crab recruits that biologists have been tracking for years. "That is what's fueling the increase in the harvest this year. We're just getting the very beginning of that year class," said......... http://www.adn.com/money/welch/story/1004091.html

Danish commandos 'monitoring hippies' on Arctic offshore rig #artcticloons

Image by Steve Rhodes via Flickr Alaska Dispatch | May 31, 2011 Armed Danish commandos have (possibly) been summoned to monitor Earth-loving "hippies" clinging to the underbelly of an Arctic deepwater oil rig  off the coast of Greenland , sources say. The environmental non-governmental group  Greenpeace  has published  statements and  video  showing its activists aboard two ships that are attempting to "interfere" with oil exploration going on in the Davis Strait, 100 miles west of Greenland. This business has in turn prompted the Kingdom of Denmark to launch two ships and a few helicopters to monitor the Greenpeace interference. The  Leiv Eriksson  is the source of all this Arctic bait and switch. British oil company  Cairn Energy  is attempting to drill four wells at depths of at least 5,000 feet this summer in "iceberg-strewn sea" with the 53,000-ton offshore oil rig, which has made its way to Arctic waters after a month of failed attempts by Green
