Description
Summary:The first experiments in maturation, spawning and larval rearing of spotted seatrout Cynoscion nebulosus in Sisal, Mexico were conducted. Sexual maturation and spontaneous spawning in wild captured fish after 20 months in captivity were obtained. In a spawning period of 88 days, 28 spawns were observed, of which 17 were viable. In total 28 x 106 eggs were collected, 70% of viability and 91% of fertilization was observed. The spawned eggs had mean diameter of 710 ± 8 µm with an oil droplet of 199 ± 9 µm.
