Abstract: The objective of this experiment was to determine the efficacy of different GnRHa doses for the induction of the spawning in meagre broodstock born in captivity. Five experimental groups were established, and one control group that was not injected. Fish were acclimated in six 10 m3 tanks, and in each tank there was 3? and 4? with an average weight of 8.33±0.97 and 8.47±1.09 kg respectively. Throughout the experimental period (April 14- June 2 of 2009), broodstock were induced on a weekly basis. Each time one female and two males from each of the five experimental groups were induced with an injection of GnRHa at the doses of 10, 20, 30, 40 and 50 ?g.kg-1 respectively. No significant differences were found in any of the controlled parameters: % of injected females with spawning, latency period and % of spawns. Although the highest spawning ratio was obtained with the lower doses, a statistically significant negative correlation between the doses and percentage spawning was found.
