Abstract
Polyploidy was induced in rainbow trout Salmo gairdneri when fertilized eggs were immersed in 36 C water for 1 minute. Triploids were produced if the eggs were treated 10 minutes after fertilization; tetraploids were produced by treatments 5 hours after fertilization. Sterile triploid trout and salmon potentially could grow and survive better than normal fish at sexual maturation. Heat‐shock techniques also should be useful in the production of gynogenetic diploid trout and salmon for biological studies and breeding programs.This publication has 4 references indexed in Scilit:
