New ASMI website offers easy access to recipes, nutrition and sustainability info. Juneau, Alaska (PRWEB) May 15, 2013 The summer harvest season for wild Alaska salmon officially opens tomorrow, May 16, with a projected harvest of 179 million fish. Should the harvest reach this prediction, 2013 will mark the eighth largest Alaska salmon season on record and a 40% increase from last year’s catch of 127.1 million fish. The season kicks off with the arrival of king and sockeye in the...
University of Washington Imagine having a daylong Thanksgiving feast every day for a month, then, only pauper's rations the rest of the year. University of Washington researchers have discovered Dolly Varden, a kind of trout, eating just that way in Alaska's Chignik Lake watershed. Organs such as the stomach and intestines in the Dolly Varden doubled to quadrupled in size when eggs from spawning sockeye salmon became available each August, the researchers found. They were like...
Wildlife Conservation Society Grizzly bear, wolverine, and bull trout among species ranked as 'highly' vulnerable to climate change and road use A new report from the Wildlife Conservation Society Canada (WCS Canada) creates a conservation strategy that will promote wildlife resiliency in the Southern Canadian Rockies to the future impacts of climate change and road use. The report's "safe passages and safe havens" were informed in part by an assessment of six iconic species—bull...
University of Oregon-led study in the Umpqua River Valley provides a pointer for river conservation efforts A study of the Umpqua River basin in the Oregon Coast Range helps explain natural processes behind the width of valleys and provides potentially useful details for river restoration efforts designed to improve habitats for coho salmon (Oncorhynchus kisutch). Coho salmon thrive in broad, flat valleys that contain multiple auxiliary channels to the main river. These valleys formed...
April Flowers for redOrbit.com - Your Universe Online A new analysis of over 56 years of data has revealed that sockeye salmon use a magnetic map to return to their spawning grounds after years at sea. The findings of this study were published online in the journal Current Biology. "To find their way back home across thousands of kilometers of ocean, salmon imprint on the magnetic field that exists where they first enter the sea as juveniles," said Nathan Putman of Oregon State...
Be careful what you eat, says University of Notre Dame stream ecologist Gary Lamberti. If you're catching and eating fish from a Lake Michigan tributary with a strong salmon run, the stream fish — brook trout, brown trout, panfish — may be contaminated by pollutants carried in by the salmon. Research by Lamberti, professor and chair of biology, and his laboratory has revealed that salmon, as they travel upstream to spawn and die, carry industrial pollutants into Great Lakes streams...
CORDOVA, Alaska, Dec. 4, 2012 /PRNewswire/ -- Prince William Sound Aquaculture Corporation (PWSAC) recently released the results of a comprehensive study on the impact of its programs on the economy, Alaska's seafood industry, sport, subsistence and personal use fisheries. Significant benefits to the state and regional economy were outlined, along with ways in which the programs could be expanded to produce greater economic benefit.

The arbitrary U.S.-Canadian political border contributed to international tensions and led to a fierce competition that almost decimated the salmon industry, says a Linfield College professor in a new book. McMINNVILLE, Ore. (PRWEB) October 03, 2012 The waters off the coast of Washington state and British Columbia were once filled with fish pirates and border bandits vying for salmon, according to a new book by Linfield College Professor Lissa Wadewitz. The Nature of Borders: Salmon,...
A novel genetic study led by the University of Colorado Boulder has helped to clarify the native diversity and distribution of cutthroat trout in Colorado, including the past and present haunts of the federally endangered greenback cutthroat trout. The study, led by CU-Boulder postdoctoral researcher Jessica Metcalf, was based largely on DNA samples taken from cutthroat trout specimens preserved in ethanol in several U.S. museums around the country that were collected from around the state...
Climate change, pollution, the extraction of water for irrigation and overfishing all threaten the survival of the common trout. This fish is very sensitive to changes in its environment and, according to the Spanish study, its habitat will have reduced by half by the year 2040 and will have completely disappeared from Iberian rivers by 2100, so its population will become extinct. Global warming is threatening the existence of many fish species, especially those in the salmonid family,...

Seema, also known as Sima and Sema Japanese salmon, Cherry salmon, or Masu salmon (Oncorhynchus masou) is a salmon of the western Pacific Ocean which includes the Kuril Islands, Kamchatka, Primorsky Krai, Japan, Korea and Sakhalin. In Taiwan a landlocked subspecies known as the Taiwanese salmon or the Formosan salmon (Oncorhynchus masou Formosanum) also exists. The Seema favors a temperate climate that is around the area of 65 degrees north to 58 degrees north in the sea. The Seema also...
The Golden Trout (Oncorhynchus mykiss aguabonita) is a subspecies of the Rainbow Trout (Oncorhynchus mykiss). It is also known by the name California Golden Trout and is native to Golden Trout Creek, Volcano Creek and the South Fork Kern River in California. It is most likely found at elevations 10,000 feet above sea level. This subspecies is also commonly placed with other subspecies of rainbow trout known as redband trout. The Golden Trout has flanks with a red, horizontal band along the...
The Gila Trout (Oncorhynchus gilae gilae) is a species of fish native to the southwest United States (Arizona and New Mexico). It is an endangered species. Once occupying upwards of several hundred miles of streams, the Gila Trout's area was reduced to only 20 miles all located in the Gila Wilderness and Aldo Leopold Wilderness by 1967. The causes of its decline was due to competition with introduced game fish and habitat loss (caused by loss of water and shade-giving trees). Habitat loss was...
Redband Trout is a fish name that may be a synonym for the rainbow trout, but is used more narrowly for two subspecies with well-defined geographical distributions in the United States: the Columbia River Redband trout, (Oncorhynchus mykiss gardenia), found in Montana, Washington and Idaho, and the Great Basin Redband trout, (Oncorhynchus mykiss newberrii), found in southeastern Oregon, and parts of California and Nevada. Both subspecies are popular game fishes. The redband trout is...
