| Habitat |
Sockeye fry will hide during the day and emerge at night. Some sockeye fry will head to sea immediately but most will spen 1 to 2 years in a fresh water lake before heading to sea. Occasionally fish will remain 3 or 4 years in a fresh water lake before migrating. Once in a lake, the fry will stay near shore for several weeks feeding on insect larvae. When they move to deeper water they feed on plankton.
When they migrate to sea, they again stay near shore feeding on small fish, insects and forms of plankton. As they grow they venture farther out to sea and other fish become a more important part of their diet.
There are two forms, the anadromous form known as the sockeye and the landlocked form (with a much smaller maximum size) known as the kokanee (Ref. 27547).
The fresh water sockeye or Kokanee spend most of their lives in a lake. They feed mostly on plankton insects and bottom feed. Kokanee fry will occasional become sea run Sockeye. Kokanee will live between 2 and seven years depending on the strain. |
| What do they Look Like? |
Generally both Sockeye and Kokanee vary from steel blue to green-blue on the back and head, they have silver sides and white to silver belly. They have no definitive back spots but may have speckling or irregular marks on the dorsal fin.
Spawning fish generally turn olive to bright green on the head and back. The snout and upper jaw will be black with red adipose and anal fins. Females are generally less colourful than males. Some Sockeye runs will display different colourations such as green to yellowish backs and heads with little or no red colour at all.
Sockeye are streamline and tapered towards both the head and tail. With a somewhat squashed look from side to side. They have a blunt pointed head with relatively small eyes. |
