Efecto de la ablación ocular en el crecimiento de juveniles de Langosta (Panulirus argus)
MetadataShow full item record
Two experiments were accomplished in (P. argus) lobster juveniles, for evaluate unilateral and bilateral eyestalk ablation. First one with initial weight 120 g the juveniles reach (237 g and 146 g) in 180 days, survivals (75% and 72%), NBI (50.4 and 27), growth rates (0.731 g/day and 0.231 g/day), SGR (0.47%/day and 0.16%/day) respectively; significant differences were found between unilateral and bilateral ablation on final weights, SGR and NBI. On a second experiment, using unilateral ablation with initial weight of 30 g the juveniles reach 130 g in 154 days, survival 66.6%, NBI 58.7, growth rate 0.651 g/day and SGR 0.95%/day. Significant differences appear between final weight, SGR, and NBI with control. The unilateral ablation shows the best records and is recommended as a method for accelerate growth in lobster’s juveniles.
