DESCRIPTION
-
The average length of the fresh water
form is 12-18 inches long and 18-24 inches
in anadromous stocks. The color is variable
with size, locality and habitat. Adults
living in the sea are a dark blue with
silvery sides and those living in fresh
water are a olive-green to brown. Spawning
adults turn a bright red. All are spotted.
For years, many anglers have used the
name Dolly Varden to apply to what are
now considered two different fish: the
Dolly Varden and the Bull Trout. In some
regions it's hard to make a clear distinction
between the two, while in other areas
of British Columbia the difference in
appearance is substantial.
DISTRIBUTION
-The Dolly Varden is found in the fresh
and salt waters of North America and eastern
Asia. The anadromous form do not move
out into the open ocean but remain close
to shore near the river mouths.
BIOLOGY
- The Dolly Varden is a fall spawner.
The female digs the redd and is attended
by 4-5 males. Generally this species lives
10-12 years. The bull trout is known as
the most serious predator on young salmon
and a bounty was long paid on them in
Alaska.
RELATION
TO MAN - Generally not considered
a sought after sport fish, the Dolly Varden
does have many of the sporting qualities
of other trouts. They have been sold commercially,
fresh, fresh-frozen, canned or dried.
