Salmon / ˈ s æ m ə n / is the common name for several species of ray-finned fish in the family fish in the same family include trout, char, grayling and are native to tributaries of the North Atlantic (genus Salmo) and Pacific Ocean (genus Oncorhynchus).Many species of salmon have been introduced into non-native environments such as the Great Lakes of North.

U.S. wild-caught coho salmon is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.
NOAA Fisheries works in cooperation with federal, state, tribal, and Canadian officials to manage these commercial, recreational, and tribal harvest of salmon and steelhead in ocean and inland waters of the West Coast and Alaska. The traditional range of the coho salmon runs from both sides of the North Pacific Ocean, from Japan and Coho salmon studies in Southeast Alaska Russian, around the Bering Sea to mainland Alaska, and south all the way to Monterey Bay, California.
Coho salmon have also been introduced in all the Great Lakes, as well as many other landlocked reservoirs throughout the United States.
Alaskans who have fished for salmon consistently over the years know it: Alaska’s salmon, especially king salmon, are getting smaller.
Now, a new Coho salmon studies in Southeast Alaska. Comparing mean body length pre to mean body length post, Chinook salmon exhibited the greatest magnitude decline, averaging an % decline in body length, compared to % in coho.
Diet composition by major prey taxa of juvenile pink, chum, sockeye, and coho salmon captured in surface marine waters of northern Southeast Alaska, to Annual values are averaged over June, July, and August.

Alaska´s highly prized salmon are being impacted by climate change, according to study that found the prized fish has shrunk over the past six years and some are 8% smaller. To calibrate these index area counts, mark-recapture studies of the coho salmon escapement have been conducted in five years:, and Results from these studies indicate that the index area counts represent about % of the drainage-wide adult coho salmon escapement.
Alaska’s highly prized salmon - a favorite of seafood lovers the world over - are getting smaller, and climate change is a suspected culprit, a new study reported, documenting a. More than any other region, transboundary salmon migration is of critical importance to governance as many of the Chinook salmon and coho salmon caught here were hatched outside Alaska.

This study was investigated with information from a stock assessment program (), catch sampling programs of the Canadian inriver gillnet fishery, the U.S. commercial gillnet fishery in Taku Inlet, the troll fishery in Southeast Alaska, and the U.S.

Streams in karst landscapes showed higher al-kalinities (1, µeq/L) than streams not influenced by karst landscapes ( µeq/L). A significant, positive relationship was observed between alkalinity and density of coho salmon. The second largest of the five Alaska Salmon species. Average weight is 12 pounds.

Coho salmon (Oncorhynchus kisutch) also may be relatively early coloniz-ers. In a comparison of two year-old streams, Milner and Bailey () showed that the enhanced channel stabil-ity of a lake-influenced stream supported greater densities of juvenile coho salmon than a nonlake system.
