- Title
Three-year Hatchery and Field Evaluation of Four Strains of Rainbow Trout.
- Authors
DWYER, WILLIAM P.; PIPER, ROBERT G.
- Abstract
The performance of four strains of rainbow trout, (Salmo gairdneri) was evaluated under hatchery and field conditions. Growth, conversion, and survival were measured in the hatchery; catchability, growth and longevity data were collected in the field. Fish from each strain were stocked at equal densities into two ponds near Three Forks, Montana, for a replicated field evaluation. The domestic Winthrop and Spring Standard Growth strains grew faster, converted food more efficiently, and were harvested at a faster rate than the wild McConaughy and Fish Lake strains. However, the McConaughy and to some extent the Fish Lake strains remained in the fishery longer--up to 3 years, at which time the project was terminated.
