A Comparison of Precociousness in Three Graded Size Classes of Hatchery-reared Rainbow Trout Salmo GairdneriMicroform - 1986
Rainbow trout, as in most other salmon species, produce males which mature early and spawn as two year olds. Rapid growth rates in the first year are regulated by both environmental and genetic factors, and affect sexual maturation rates. With the onset of sexual maturity, growth rate is reduced and the fish becomes unattractive to a sport fishery. This study was conducted to determine the feasibility of grading out faster growing juvenile rainbow trout in a hatchery population to reduce the number of precocious males in the lake stocking program in B.C.
