The size of an adult Coho may measure more than 2 feet in length
and can weigh up to 36 pounds. However, the average weight of a sport
fish caught Coho is 8 pounds. Habitat
~ Coho spend approximately the first half of their life cycle rearing
and feeding in streams and small freshwater tributaries. Spawning
habitat is small streams with stable gravel substrates. The remainder of
the life cycle is spent foraging in estuarine and marine waters of the
Pacific Ocean. The species was historically distributed throughout the
North Pacific Ocean from central California to Point Hope, Alaska,
through the Aleutian Islands, and from the Anadyr River, Russia, south
to Hokkaido, Japan. Feeding
Habits
~ In their freshwater stages, Coho feed on plankton and insects, and
switch to a diet of small fishes as adults in the ocean. The diet of
adult Coho include herring, pilchards, squid, and crustaceans.
