Coho Salmon


Common Name(s):
Silver salmon, sea trout, silver sides
Description:
Adults in salt water or newly arrived in fresh water are bright silver with small black spots on the back and on the upper lobe of the caudal fin. They can be distinguished from Chinook salmon by the lack of black spots on the lower lobe of the tail and gray gums.
Similar Fish:
Chinook salmon, Atlantic salmon
Feeding Habits:
Coho salmon smolts tend to stay close to shore at first, feeding on plankton. As they grow larger, they move farther out into the ocean and switch to a diet of small fish.
Range:
The Coho salmon are found in coastal waters of Alaska from Southeast to Point Hope on the Chukchi Sea and in the Yukon River to the Alaska-Yukon border. They have been found as far south as Baja, California and have been transplanted into the Great Lakes.
Habitat:
Some Coho migrate only a short distance into good feeding areas, and stay there; others travel extensively. Coho salmon from California to British Columbia tend to travel north and spend the summer along the central Alaskan coast. Most Alaskan fish travel a counter clockwise path following the currents in the north Pacific Ocean.
Typical Size:
Adult Coho salmon usually weigh 8 to 12 pounds and are 24 to 30 inches long. They will live an average of 3 years.
World Record:
33 pounds, 4 ounces (Source - IGFA)
