Spawning kinetics in the gilthead sea-bream, Sparus aurata L. after low doses of human chronic gonadotropin

This paper reports the temporal pattern of hormonally induced spawning in Sparus aurata females reared in captivity. A low dose of human chorionic gonadotropin (100–400 i.u. kg−1 body weight), administered to females with oocytes in the last stages of vitello genesis, induced a daily cycle of maturation, ovulation and spawning of fertilizable eggs. This cyclic pattern lasted for a period of 4–100 days. In fish injected with saline and most of the untreated fish, all vitellogenetic eggs underwent rapid atresia.
