Escape vents in traps for the fishery of the California spiny lobster, Panulirus interruptus, in Baja California Sur, Mexico

In order to determine the effect of escape vents in traps used in the California spiny lobster, Panulirus interruptus, fishery along the Pacific coast of Baja California Sur (Mexico), comparative fishing operations were conducted with normal traps and traps modified with escape vents. It was found t...

It was found that carapace height is directly related to trap selectivity. The results show the effectiveness of the vents in allowing sublegal lobsters to escape and in enhancing the catch rate of lobsters with carapace lengths greater than 82.5 mm (minimum legal size). However, the decrease in the number of sublegal lobsters in the modified traps is not as great as expected, since they constitute from 82.6 to 91.6% of the catch, depending on the type of vent and fishing area. This indicates the need to conduct new studies to determine the best type of vent. Con el fin de evaluar los efectos de ventanas de escape en trampas utilizadas para la captura de la langosta roja, Panulirus interruptus, en la costa del Pacífico de Baja California Sur (México), se efectuaron operaciones de pesca comparativa con trampas normalmente utilizadas por los pescadores de la región, carentes de dispositivos de escape, y con trampas modificadas, provistas de ventanas de escape. Se encontró que la altura del cefalotórax está directamente relacionada con la selectividad por tallas. Los resultados muestran que el uso de las ventanas conlleva la disminución en la captura de individuos de talla sublegal y tiende a mejorar la tasa de captura de langostas mayores de 82.5 mm de longitud del cefalotórax (talla mínima legal). Sin embargo, el decremento en el número de langostas sublegales en las trampas modificadas no es tan grande como el esperado, pues constituyen del 82.6 al 91.6% de la captura, dependiendo del tipo de ventana y área de pesca. Esto implica la necesidad de efectuar nuevas pruebas para determinar el mejor tipo de ventana.
