T
HE WORDS WALLEYE FRY -
FOR MANY - CONJURE UP
THOUGHTS OF THE DELICIOUS,
MILD-TASTING MEAT FROM THIS
TOOTHY FISH. BUT RIGHT NOW FOR
THE WYOMING GAME AND FISH
DEPARTMENT, THESE WORDS ARE PART
OF INITIAL WORK TO EVENTUALLY
RAISE ITS OWN COOL/WARM-WATER
FISH SPECIES - INCLUDING WALLEYE.
The first year proved it could be done, the
second showed more success and the future looks
bright for its continuation.
" One year tells us we can do it, two years
tells us we know we can do it, " said Lars Alsager,
hatchery superintendent at the Dan Speas Fish
Hatchery in Casper.
Just over 54,000 walleye were raised at Speas
and released in two Wyoming waters in 2020 -
the first year Game and Fish conducted this work.
Those walleye were stocked in Hawk Springs
32 | August 2021
Reservoir in Goshen County and Ocean Lake
in Fremont County. About 75 percent of the
walleye raised at Speas survived to be stocked.
" That's as good as work being conducted in
research, " Alsager said. " Anything over 50 percent
is hitting a home run, so I guess in a lot of ways
we hit a grand slam with it last year. "
Thanks to the purchase of a self-cleaning larval
tank, Game and Fish increased its production of
walleye this year to about 100,000 fish stocked
in four waters in the state: Ocean Lake and three
waters in the Cody region -- Wardell, Harrington
and Deaver reservoirs.
Prior to 2020 Wyoming's 10 hatcheries and
rearing stations only raised cold-water fish,
which includes trout and kokanee salmon. The
only warm/cool-water species raised in the state
prior to this work was tiger muskie, however,
Game and Fish get the fry from Nebraska and
do not spawn them in Wyoming. All other cool/
warm-water fish stocked in Wyoming are brought
in from other states through trade agreements.
Most of the work to raise cool/warm water fish
has focused on walleye thus far. Why? Because
Game and Fish stocks about 1.2 million walleye
annually in Wyoming waters.
