Abstract: For this study, a total of 19 grater amberjack (Seriola dumerili) broodstock were used. Females with, oocytes bigger than 600µ, and fluent males with a mean weight of 10.72±1.22 kg, females, and 10.77±2.33 kg males. The experimental tanks were circular tanks of 40 m3 capacity. One of the tanks was not induced and the other two were with GnRHa, one with injections and the other by implants. The number of eggs obtained in natural spawning (25.60 million) is higher than those obtained by injections (12.9 million) and implants (10.5 million). The number of eggs per female was 12.80 million, in natural spawning, and 4.30 and 3.51 million, in induced with injections and implants, respectively. In number of eggs per spawn, significant differences was observed, between natural spawns (1.11 million), and induced spawning’s (0.44 and 0.21 millions, injected and implants respectively). Significant differences was also found, in number of eggs per Kg female/spawn, between natural spawning’s (56,700 eggs), injection induced (37,200 eggs) and implants (25,200 eggs).
