Triploid trout are created by heat-shocking the fertilized eggs. This results in fish that contain 3 sets of chromosomes. Half of the fish will be XXY (triploid males) and half will be XXX (triploid females). Both should be sterile or infertile.
Male triploids may still develop functional gonad tissue and may participate in spawning behavior even though they are sterile.
Females do not develop gonads (or, develop "string" like gonads) and do not exhibit spawning behaviour.
