ABSTRACT:
A method for the induction of tetraploidy in channel catfish by heat-shocking fertilized eggs is described. Fertilized catfish eggs are treated after a preliminary incubation period and prior to first cell division cleavage by immersing the fertilized eggs in water at a temperature of about 40.degree. C. to about 43.degree. C. for a temperature-dependent period of time ranging from about 1 to about 4 minutes. Incubation of the heat-shocked eggs allows maturation to tetraploid catfish fry. Breeding of tetraploid catfish with normal diploids produces rapid growing triploid offspring.
