Coho Salmon; also silver salmon, dog salmon
Kisutch is the Russian name for this fish around Kamchatka, USSR. The coho salmon, identifiable by the small spots on the back and upper tail-fin lobe, stays in fresh water for its first year, then swims down river to the Pacific Ocean, where it matures in about three years. Average adults weigh about ten pounds, though the largest recorded coho, 38.5 inches long, weighed 31 pounds. The common name coho possibly evolved from the word Halkomelem, from a Salishan dialect of southwest British Columbia.
Mature coho salmon have dark blue backs and silver sides, but during the spawning phase they turn bright red on their sides and blue-green on their heads and backs, and develop the hooked nose—oncorhynchus—as seen in the photo above.

Meriwether Lewis described this species on March 16, 1806, at Fort Clatsop:
Lewis drawing a sketch of it, he painted a beautifully detailed word-picture.
Neither this fish nor the salmon are caught with the hook, nor do I know on what they feed.
In general, anadromous fish en route back to their redds do not eat, although they will strike hard at artificial lures.
