DESCRIPTION
-
Coho Salmon are usually 18-24 inches in
length and 8-12 pounds in weight. The
head is conical with a snout bluntly pointed
but greatly extended, thickened and turned
down in breeding males. These breeding
males are characterized by their inability
to close their mouths. All have sharp
teeth on both jaws. Adults in the ocean
are colored a steel-blue to slightly green
with silver sides, white bellies and small
black spots on the back. The coloring
is less spectacular in fresh water specimens.
DISTRIBUTION
-The coho salmon occurs naturally only
in the Pacific Ocean and its tributary
drainage. It can also be found in some
fresh water areas including the Great
Lakes.
BIOLOGY
- After spending up to 18 months at sea
these 3-5 year old adults migrate late
in the season and over a prolonged period.
Often they school at the mouths of rivers
and move up when fall rains increase rives
flow. Generally a coho salmon will not
travel more than 150 miles up river from
the sea or lake. Spawning takes place
anywhere between October and January.
After the female prepares the redd she
will lay 2100-2789 eggs guarding them
until she dies a few days later. The fry
emerge from early March to late July and
although some will migrate almost immediately,
most remain at least one year in fresh
water lakes or streams.
RELATION
TO MAN - The coho salmon has always
been considered important by commercial
and sport fishermen in British Columbia.
The best catches are made from July to
September with a peak in August. Fly fisherman
take cohos at stream mouths using bucktail
flies and anglers using frozen or pickled
herring have plenty of luck. In fact on
the average B.C. anglers catch 110 000
grilse per year. Coho salmon can be canned,
mild cured, smoked or if troll caught,
sold fresh or fresh-frozen.
