Other names: Silver Salmon
Coho salmon typically weigh between 8-12 pounds and measure, on average, 24-30 inches long. Smaller coho, ranging in length from 12-20 inches, may be seen spawning with larger fish. These smaller male coho are referred to as “jacks” and return to spawn after only one year in the ocean. Other species of salmon also have precocious jacks that comprise small segments of annual spawning populations. Coho salmon closely resemble chinook salmon in ocean and spawning coloration. Distinguishing characteristics for coho salmon include spots on the upper lobe of the caudal fin (not on the bottom lobe), white instead of black gum coloration, and an overall smaller size. Coho are typically not quite as “beefy” in appearance compared with chinook. They are often targeted by recreational anglers but are typically not as highly esteemed as chinook salmon.
