Biology & Habitat

Appearance

Commonly called silver salmon, coho have dark metallic blue or greenish backs with silver sides and a light belly. While they are in the ocean, they have small black spots on their back and on the upper lobe of the tail. The gumline in the lower jaw has lighter pigment than on Chinook salmon. In fresh water, spawning coho are dark with reddish-maroon coloration on the sides.

Biology

Coho salmon are anadromous—they hatch in freshwater streams and spend a year in streams and rivers then migrate out to the saltwater environment of the ocean to feed and grow. Some stocks of coho salmon migrate more than 1,000 miles in the ocean, while other stocks remain in marine areas close to the streams where they were born.

Where They Live

Range Coho salmon are found throughout the North Pacific Ocean and in most coastal streams and rivers from Alaska to central California. In North America, they're most abundant in coastal areas from southeast Alaska to central Oregon. Coho salmon have also been introduced in all the Great Lakes, as well as many other landlocked reservoirs throughout the United States.

How to Buy & Source

Availability

Fresh mainly in summer through late fall and frozen year-round.

Source

U.S. wild-caught mainly from Alaska with smaller amounts from Washington and Oregon.

Commercial Fishery & Harvest

Commercial fishery: In 2023, commercial landings of coho salmon totaled 16 million pounds and were valued at $16.6 million, according to the NOAA Fisheries commercial fishing landings database . Most of the U.S. coho salmon harvest comes from Alaska (over 90%) with smaller percentages from Washington and Oregon. Gear types, habitat impacts, and bycatch: Coho salmon are mainly harvested in commercial troll fisheries in the Pacific Northwest and Alaska. Troll vessels catch salmon by "trolling" their lines with bait or lures through groups of feeding fish. To retrieve hooked fish, the lines are wound on spools by hand or hydraulically, and the fish are gaffed when alongside the vessel. The troll fishery produces low-volume, high-quality product.
