Assessment of the Pacific red snapper (Lutjanus peru) fishery in the southwestern Gulf of California

 The Pacific red snapper (Lutjanus peru) fishery in the southwestern Gulf of California was analyzed with an age-structured simulation model. In addition to natural mortality (M) and fishing mortality (F), the model incorporates juvenile by-catch mortality (f) caused by the shrimp fishery i...

Se analizó la pesquería del huachinango (Lutjanus peru) en la región suroeste del Golfo de California con un modelo de simulación estructurado por edades. Además de la mortalidad natural (M) y la mortalidad por pesca (F), el modelo incorpora la mortalidad incidental de juveniles (f) que se da por la pesca de camarón en la zona. Se probaron cuatro escenarios de simulación en donde se combinaron diferentes niveles de mortalidad. Contrario a lo que señala la Carta Nacional Pesquera, los resultados del modelo mostraron que la pesquería no tiene posibilidades de desarrollarse si F y f continúan sin ser reguladas como hasta ahora. De acuerdo al modelo, la pesquería podría desarrollarse mediante una regulación efectiva de ambas fuentes de mortalidad, lo que implica medidas de control tanto para la flota artesanal, como para la flota camaronera.
