Synopsis

The development of various secondary sexual characteristics in salmonids is described, together with a method of preventing sexual maturation by surgical gonadectomy. The major problem in the application of this technique is the regeneration of male testicular tissue, and it is suggested that the practical solution is the use of hormonal feminisation techniques prior to gonadectomy.
