Hormone induced spawning (HCG), and embryonic and larval development of the leopard grouper, Mycteroperca rosacea (Streets, 1877)
Induced spawning of two wild females of the leopard grouper, Mycteroperca rosacea, was obtained using Human Chorionic Gonadotropin (HCG) supplied in two dosages: a first injection of 1000 IU/kg and a second of 500 IU/kg, 24 h apart. Of the four treated females, two had a positive spawning response,...

Induced spawning of two wild females of the leopard grouper, Mycteroperca rosacea, was obtained using Human Chorionic Gonadotropin (HCG) supplied in two dosages: a first injection of 1000 IU/kg and a second of 500 IU/kg, 24 h apart. Of the four treated females, two had a positive spawning response, releasing approximately 40,000 eggs/fish. These were fertilized with mature male sperm. The fertilization rate obtained for each female was 10% and 0%. Complete embryonic development, and the morphology of eggs and larvae are described until the first feeding. Eggs were spherical, buoyant and transparent, with a diameter of 872.8 ±15.4 ∞m (ranging from 850.4 to 912.5 ∞m) and an oil droplet diameter of 177.3 ± 7.0 ∞m.
