Resumen

Recientemente se ha demostrado que dos especies de gambas rojas de profundidad (Aristeus antennatus and Aristaeomorpha foliacea) tienen el potencial de sostener una pesquería viable en el mar Jónico griego (Mediterráneo oriental). En este trabajo investigamos i) la evolución que esta nueva pesquería de gambas puede tener ante distintas medidas de gestión, y ii) cuáles serían las tasas de extracción del recurso más adecuadas teniendo en cuenta la incertidumbre sobre el recurso. Además analizamos los efectos que puedan tener sobre la pesquería el aumento del precio del combustible y cambios en el precio de mercado. La proyección de las consecuencias biológicas y económicas de las acciones de gestión, así como los efectos de cambios en el mercado sobre las entradas y salidas antes de ser aplicadas puede ayudar a los gestores a seleccionar las opciones de gestión más adecuadas. Proporcionamos una aproximación al modelo mediante análisis bio-económico de simulación. Los resultados de este estudio muestran que el esfuerzo de pesca puede aumentar en un 50 a 100%, aumentando la rentabilidad de la flota, sin comprometer negativamente la sostenibilidad de la pesquería.
