Kokanee look very much like sockeye
salmon. Kokanee in non-breeding
condition have bright silver sides and a
dark grey to blue back, sometimes with a
few dark markings on the dorsal fin (the fin
on its back). The anal fin (the lower fin nearest the tail) has a long base and the
trailing edge is quite angled rather than
square, features often used to distinguish
kokanee from char or trout. During
spawning season, kokanee change colour,
usually turning crimson with a green head,
but sometimes black. The males develop
long jaws, hooked snouts, and large teeth.
A slight hump forms behind their head.
Spawning females are not as colourful as
the males and their overall shape does not
