Comparación entre la calidad de puestas naturales e inducidas, mediante inyección e implante de GnRHa, del pez de limón (Seriola dumerili)

Abstract

For this study, a total of 19 greater amberjack (Seriola dumerili) broodstock were used. Females with oocites bigger than 600_, and fluent males with a mean weight of 10.72±1.22 kg, fameles, and 10.77±2.33 kg males. The experimental tanks were circular tanks of 40 m3 capacity. One of the tanks were not induced and the other two were with GnRHa, one with injections and the other by implants. Best results, in all parameters studied were with natural spawns, with a 84.37% of fertilization, 92.21% of viable eggs at 24 hours of spawn, 96.60% of hatching, 69.91% of larvae one day after hatching and 10.78% of 5 day life larvae.
