Obtención de puestas del pez de limón (Seriola dumerili) mediante GnRHa, comparación de la eficacia de la induccion con implante e inyección

Abstract

The three males and three females of tank 2 were induced with EV-500_g GnRHa implants, one implant (500_g) was used for the females and half that doses for males. The first injection was on the 3rd of June and the last one spawning’s the 21st of October, a total of 37 injections and 29 spawns were obtained. The first implant was introduced the 20th of June, the last spawn was on the 16th of October of the implant set the 14th, a total of 17 implants and 38 spawns were obtained. The number of spawns per induction was significantly higher (P < 0.01) in implanted females, no significant differences were found in latency period which was of 43-44 hours.
