The Coho salmon was introduced to
Ontario waters in the late 1800's. In the 1960's they were
stocked in large amounts and the permanent population became
Adults are steel - blue to slightly green on
the back, gleaming silver on the sides, and white on the
underbelly. There are little black spots on the back and sides
right above the lateral line, on the base of the dorsal fin, and
on the upper half of the caudal fin. Coho are different from the
Chinook salmon and other salmon of the Ontario Great Lakes by
having the inside of their teeth set in white coloured gums,
their tail is slightly forked with many spots on the top half,
and having 12-15 rays in thier anal fin.
The coho salmon is a tremendously popular
fish for sportfishing found throughout the Great Lakes. It was
the prime choice of the Pacific Salmons that were to be stocked
in the widespread Great Lakes rehabilitation program of the
1960’s. This quickly growing, predatory fish was originally
planted to assist in reducing the alewife population while also
offering great angling to Great Lakes fishermen. The results of
the stocking program are excellent, and Great Lakes salmon
fishing is well-known the world over.
The Coho salmon stays for the most part in the cold deep waters
of the great Lakes. It returns to shoreline tributaries and
streams to spawn.
