ABSTRACT
A Colorado squawfish hatchery feasibility study was initiated.a.t the
Rifle Falls State Fish Hatchery near Rifle, Colorado. An engineering
plan was prepared to accomodate research and production of 100,000
young fish annually. The hatchery plan includes: a hatching house
to research spawn taking techniques, egg incubation, and fry rearing;
two half-acre ponds and one quarter-acre pond for rearing fingerlings
and overwintering brood fish, respectively; four concrete raceways for
additional fingerling rearing space;. a pollution abatement pond to
restore water quality; and, a quarantine raceway to hold wild brood
fish.
