Eficacia de la inducción hormonal con GCH y GnRHa en reproductores de corvina (Argyrosomus regius).

Abstract

Eighteen mature meagre (Argyrosomus regius) broodstock, born in captivity, were divided in 3 experimental groups in ratios of 3 _ and 3 _ each. One group was inducted by injections of hCG, the other with GnRHa and the last group with implants of GnRHa. In all three treatments all females responded positively to the hormonal treatment. Statistically differences were found, in the number of spawns per induction, of females induced with hCG with the GnRHa treatments. Latency period was longer in spawns from GnRHa implants, and showed statistically differences with the other two treatments.
