Perspective of the pink shrimp (Farfantepenaeus duorarum burkenroad) fishery of Campeche bank, Mexico

The pink shrimp, Farfantepenaeus duorarum, fishery of Campeche Bank, Mexico, was analyzed in order to characterize it and to test the effect of different fishing intensities upon the stock. Catch data consisted of the number of shrimp per commercial class for the 1986–1993 period. A virtual populati...

Catch data consisted of the number of shrimp per commercial class for the 1986–1993 period. A virtual population analysis structured by age was applied to determine seasonal recruitment and fishing mortality patterns with respect to age, as well as the stock-recruitment relationship. With these results, an age-structured deterministic simulation model was developed, which diagnosed the fishery and defined the effects of different exploitation scenarios by considering changes in fishing mortality. Results show that the decreasing catch tendency through the period of analysis is related to recruitment failures. The analysis indicated that a way to mitigate the low recruitment problem is to control and reduce fishing mortality, but stock density will continue to decrease if the current fishing intensity is maintained. Con el fin de caracterizar el estado de la explotación del camarón rosado Farfantepenaeus duorarum en la Sonda de Campeche, México, y explorar la respuesta del recurso ante diferentes niveles de intensidad de pesca, se utilizó información proveniente de registros de captura en número de individuos por clase comercial, para el periodo de 1986 a 1993. Se aplicó un análisis de población virtual con estructura por edades y se determinaron los patrones estacionales de reclutamiento y de mortalidad por pesca con la edad y la relación entre la población de adultos y reclutas. Se desarrolló un modelo de simulación determinístico que permitió establecer una hipótesis sobre el estado de la pesquería y definir diferentes escenarios de explotación al considerar cambios en la mortalidad por pesca. En el periodo analizado se encontró una tendencia decreciente de la captura que se relaciona con una similar y continua del reclutamiento. A través del modelo de simulación se demostró que una forma inmediata de mitigar la tendencia de la pesquería es mediante el control y reducción de la mortalidad por pesca que se aplica. Si la intensidad de pesca actual se mantiene, la abundancia del recurso seguirá decreciendo.
