COHO SALMON - ONCORHYNCHUS KISUTCH
Size: Coho rank as the third largest of the Pacific salmon behind chinook and chum. The world's record sport-caught coho weighed 31 pounds, but today's largest coho rarely exceed 20 pounds; average weights range from 5 to 10 pounds. Coho sizes can vary considerably from year to year depending upon ocean upwellings, temperature, and perhaps even the number of fish competing for food.
Identification: Adult ocean coho, or those newly entered into
rivers, are silvery-sided with greenish- or bluish-colored backs. They exhibit black spots along the back and upper fins. These spots
are confined to the upper half of the caudal (tail) fin only. The gums of the lower jaw are grayish in color, but the gum color at
the very base of the teeth is whitish or cream- colored. Coho tend to darken quickly after entering their natal streams; their
heads turn a greenish color and the sides change to brown or maroon with a red lateral slash. The belly color is gray turning
to black among advanced spawners. Males develop the hooked snout characteristic of all Pacific salmon and a slightly raised
back. Females do not darken as dramatically as males and generally lack the strong red slash marks along the lateral line. White
patchy fungus growths appear on the heads and down the back and sides of fish about to spawn or spawn outs.
Oregon coho eggs were transplanted to the Great Lakes in the mid-50s and they have developed into a highly successful and popular gamefish there, with good natural spawning occurring in dozens of streams.
Quick Identification: Black spots on top half of tail, black mouth, white gums (size range 4 -15 lbs.)
Habits - Open-water fishing is the best in spring and summer, as with coho. Migration to parent streams begin in late summer, with heavy concentration at stream mouths. Stream fishing peaks sometime in September, at the onset of spawning runs.
