Efecto del tipo de hormona y del metodo de aplicación, en las producciones de reproductores de corvina (Argyrosomus regius).

[EN]In the present study, the effect of three different hormonal treatments were tested (GnRHA and hCG injected and GnRHa implanted), in meagre (Argyrosomus regius) broodstock born in captivity, and their production. The highest productions per kg of female and spawn: number of eggs, fertilized eggs, hatched larvae, and larvae 3 days old after hatching, corresponds to the treatment of GnRHa injected. The number of viable eggs, hatched eggs and larvae 3 days with GnRha injected was significantly different from those treated with hGC. No significant differences were observed in production per kg female and induction in the different hormonal treatments,
