Variations of gonadal cAMP-content of male and female rainbow trout, Salmo gairdneri (Richardson) during the reproductive cycle



Variations of gonadal cAMP-content of male and female rainbow trout, Salmo gairdneri (Richardson) during the reproductive cycle



Comparative Biochemistry and Physiology 70(1A): 53-56



Monthly samples of 20 fish were taken from a population of 215 during a complete reproductive cycle; gonads were examined histologically, and analysed for cAMP by radioimmunoassay. Male gonads showed 2 peaks of cAMP content, at stages I (little or no meiosis) and III (spermatogonia, spermatocytes and spermatids present) of gonadal development; female gonads showed 1 peak at stage III (appearance of yolk).
