Resumen del producto

To provide information towards strengthening the implementation of ecosystembased management, the dynamics of small-scale fisheries fleets in Bahia Magdalena-Almejas were analyzed based on official trip tickets data on catch per species, value and frequency of use. Fourteen fisheries were identified but scallop, shrimp and finfish, were the most important and were selected to estimate fishery performance indicators including spatial and temporal use of main species. Fishing maps were done, delimiting fishing zones related to physiographic characteristics, fishing gears, depth, and the historical distribution of catches. Complementary surveys on local knowledge were used to validate results and define types of conflicts. Direct interactions between fisheries occur when two or more overlaps in time and/or space and official regulations on fishing seasons, areas and quotas show different effects on fisher’s behavior. The information is integrated in a conceptual model of fleet behavior useful to measure some conflicts between fleets.
