Resumen del producto

The red grouper Epinephelus morio has been historically one of the most important fisheries of the Campeche Bank where two fleets of Mexico and one from Cuba participate. Currently the stock size is one third respect to the early 70s and the state of the fishery was declared as overfished. Several management measures have been taken in order to improve the state of the stock such as minimum legal size and in recent years a closed season however, the stock remains depleted. Federal government have expressed the necessity to develop specific research aimed to explore the potential use of marine protected areas as a management measure for stock recovery and maintenance of stock health. The first phase in this research, and considering fish behavior, this contribution investigates the relationship between type of bottoms with the spatial stock distribution and structure. For this we used 11 types of bottoms which are related with three different biological stages of the life history; juveniles, young adults and late adults. Quantitative analysis suggest a significant relationship between the spatial distribution of the red grouper and the bottoms. This results are the base for further modeling and exploration of the use of a MPA as management tool for fisheries.
