.-
involved in this site selection, and the genetic assessment will be helpful
in evaluating which one of these components may be operating. In any event,
the development of recovery plans may require imprinting or conditioning fish
to certain sites, and fish will be needed for this work. Fertilized eggs must
be obtained, subjected to environmental conditions, and the larvae should be
reared in the hatchery. In this manner, fish will be available for necessary
experiments to evaluate different spawning strategies. This can be best
accomplished by obtaining gametes from fish on-site.
FY 1991 work will require the following activities:
-Develop and finalize any needed MOU's between agencies, develop and
award competitive contracts, and develop needed purchase orders or sole source
contracts for assistance from identified experts.
-Identify Colorado squawfish and razorback sucker spawning areas in
which work would be performed.
-Develop sampling protoco]s and identify sampling teams for various
locations.
-Collect tissues and gametes, obtain larvae, tag fish.
-Initiate spawning basket experiments.
-Perform data analyses, integrate findings
-Develop FY 92 scope of work dependent on results of above studies.
