The present experiment studied the effect of different LHRHa doses and multiple inductions to obtain consecutive spawnings in one reproductive season of the female fat snook Centropomus parallelus. The LHRHa hormone was administered in cholesterol pellets. Five induction cycles were carried out, with 16 females and 32 males induced per cycle. Females were induced with dosages of 15, 35 and 50 μg of LHRHa/kg. The spawning rates and the number of fertilized eggs were higher at 35 and 50 μg /kg than at 15 μg /kg. Out of the 16 females, ten had three or four consecutive spawnings.
