espanolPoblaciones explotadas en la costa oeste de la peninsula de Baja California ocupan habitats complejos de arrecifes rocosos que se caracterizan por su elevada diversidad de especies de algas que conforman estos bosques de macroalgas. En esta zona se desarrolla una intensa actividad pesquera, induciendo cambios en la estructura de la comunidad bentonica, deterioro del habitat y reduccion de la biomasa de especies de alto valor comercial como la langosta roja (Panulirus interruptus). El impacto del clima fue explorado y se encontro una correlacion baja pero significativa entre el Indice de Oscilacion del Sur con el numero de reclutas de un ano de edad y con el numero de adultos. La pesqueria de langosta en esta zona, contribuye con el 85-92% de la captura total de la costa Pacifico de la peninsula. Se exploro una evaluacion actualizada de la poblacion que incluyo distintas estrategias optimas de pesca con variables socio-economicas, mediante un modelo de simulacion bajo 3 posibles escenarios como objetivos de gestion. Las estrategias de pesca fueron simuladas cambiando la mortalidad por pesca y la edad de primera captura. Se espera que estos resultados sirvan de base para proponer estrategias de gestion de la pesca de la langosta en el area de estudio. EnglishExploited stocks of the west coast of the Baja California peninsula inhabit in a complex habitat of rocky reefs characterized by high diversity of seaweeds in the kelp forest. In these fishing grounds, there is intense fishing activity, inducing changes in the structure of the benthic community, such as habitat deterioration and biomass reduction of species with high commercial value such as the California spiny lobster (Panulirus interruptus). The impact of climate was explored and a low but significant correlation between the Southern Oscillation Index and the one-year-old recruits and with the number of adults was found. The lobster fishery of this area extracts 85-92% of the total catch of the Pacific coast of the peninsula. An updated stock assessment including socio-economic optimum fishing strategies were explored using a simulation model under 3 possible scenarios as management targets. The fishing strategies were simulated by changing fishing mortality and the age of first catch. It is expected that these results will emerge in proposals for the management of the spiny lobster fishery in the study area.
