The chum salmon (Oncorhynchus keta), also known as dog salmon or keta salmon, [1] is a species of anadromous salmonid fish from the genus Oncorhynchus (Pacific salmon) native to the coastal rivers of the North Pacific and the Beringian Arctic, and is often marketed under the trade name silverbrite salmon in North America.
Aeromonas salmonicida is a Gram-negative, facultatively anaerobic, nonmotile bacterium. It is rod-shaped, about 1.3–2.0 by 0.8–1.3 μm in size, and grows optimally at temperatures between 22 and 25 °C. [1] [2] The bacterium readily ferments and oxidizes glucose, and is catalase- and cytochrome oxidase-positive.
Wild chum salmon can be consumed safely as often as once a week, pink salmon, Sockeye and Coho about twice a month and Chinook just under once a month." [52] In 2005, Russia banned importing chilled fish from Norway, after samples of Norwegian farmed fish showed high levels of heavy metals.
Salmonidae (/ s æ l ˈ m ɒ n ɪ d iː /, lit. ' salmon-like ') is a family of ray-finned fish that constitutes the only currently extant family in the order Salmoniformes (/ s æ l ˈ m ɒ n ɪ f ɔːr m iː z /, lit. "salmon-shaped"), consisting of 11 extant genera and over 200 species collectively known as "salmonids" or "salmonoids".
Example of fish length measurements. For standard weight equations, the total length is used. This fish is a tarpon. Length measurements reported for fish may be of the fish's total length, fork length, or maximum standard length.
In the fall of 2017, two additional salmon species appeared in Lagunitas Creek, pink salmon (Oncorhynchus gorbuscha) and chum salmon (Oncorhynchus keta). [12] Pink salmon, also known as humpback salmon, rarely spawn in coastal streams south of tributaries to Puget Sound in Washington state, [ 13 ] although they were reported as far south as the ...
Total length measurements are used in slot limit and minimum landing size regulations. Fishery biologists often use a third measure in fishes with forked tails, called Fork length ( FL ), the length of a fish measured from the tip of the snout to the end of the middle caudal fin rays, and is used in fishes in which it is difficult to tell where ...
Coho salmon are the backbone of the Alaskan troll fishery, though the majority are caught by the net fishery (gillnet and seine fishing). They average 3.5% by fish and 5.9% by weight of the annual Alaska salmon harvest. [15] The North Pacific yields of pink salmon, chum salmon and sockeye salmon are about 15 times larger by weight. [14]
