Genetic comparison of naturally spawned and artificially propagated Lake Ontario lake trout fry: evaluation of a stocking strategy for species rehabilitation



Genetic comparison of naturally spawned and artificially propagated Lake Ontario lake trout fry: evaluation of a stocking strategy for species rehabilitation



North American Journal of Fisheries Management. Spring; 132: 304-317



Two strategies have been used to restore lake trout (Salvelinus namaycush) to Lake Ontario. Firstly, lake trout strains from multiple wild and hatchery sources were stocked to maximize genetic variability in the lake. Secondly, hatchery stock was added each year that was reared from gametes collected from adult, hatchery-origin fish that survived to maturity in the lake (named the Ontario strain). Several hatchery strains may be present among these adults.
