New Approach to Restoring Native Western Trout

July 28, 2019 By: Erin Block

A new approach to restoring native trout in the West involves development of a “Trojan” broodstock of male brook trout that have entirely YY chromosomes. Through successive hatchery breeding, “The hope is that an all-male brook trout population will eventually occur,” writes Chris Hunt, “and the non-native fish will simply grow old and die, unable to reproduce due to the absence of females in the system.” Via Hatch Magazine.
