3. Establish hatchery,
and wild populations
of pure (Type A) greenback
cutthroat trout for broodstock.
Efforts will be pursued to
' establish greenback trout
populations in captivity and
to identify wild greenback
populations that can be used
' as broodstock to support the
establishment of additional
greenback populations within
the subspecies' historic range.

3.1 Establish a South Platte River wild broodstock. Establish/maintain
at least one lake/stream environment within the South Platte River
drainage to function as a wild broodstock source. These broodstocks
can also constitute one or more of the 20 stable populations under
Task 2.0. This Task has been completed; wild greenback populations
in Como Creek, Hunters Creek, Bear Lake and Upper Hutcheson Lake are
identified as suitable egg sources.
3.2 Establish an Arkansas River wild broodstock. Establish one
lake/stream environment within the Arkansas River drainage to
function as a practical wild broodstock source. This broodstock may
constitute one or more of the 20 stable populations under Task 2.0.
This task has been completed. Eggs have been collected from Lytle
Pond on Ft. Carson and from South Apache Creek in 1992. Boehmer
Reservoir and Native Lake also have the potential to serve as
broodstock areas, as well as the historic populations in Cascade
Creek.
3.3 Establish captive broodstocks. Establish and demonstrate the
successful use of a hatchery propagation program at the USFWS,
Bozeman Fish Technology Center, (FTC) Bozeman, Montana, using pure
(type A) greenback cutthroat trout. Movement of greenback fry and
milt between Bozeman FTC and restoration sites in Colorado will be
done in accordance with current State and Federal fish disease
policies and good fisheries management practices. Use greenback fry
from this source to reintroduce greenbacks into candidate habitats
as outlined in Task 2.4. In addition to the Bozeman program,
another successful hatchery program was demonstrated at the Saratoga
NFH in Wyoming. Both of these greenback hatchery programs ended in
1992. A hatchery program at the CDOW Experimental Hatchery was
initiated in 1989.
3.31 Collect and utilize milt from wild populations. Collect and
utilize milt from wild populations of pure (Type A) greenbacks
for fertilization of hatchery ova to minimize genetic drift
within the hatchery. This task has been completed; milt from
