Abstract
    In La Paz Bay, two artisanal fisheries operate, one based on hook-and-line, targeting snappers and groupers, and the othermainly based on gillnets, targeting species such as tilefish and haemulids. A shrimp fishery, which is not permitted to expand, alsooperates. We analyzed various harvesting strategies with the Ecopath with Ecosim modelling software, using catch-and-effortdata for target species to fit simulated biomasses. Optimal harvesting strategies for artisanal fisheries were explored using social,economic and ecological criteria. Several harvesting strategies were simulated: continuation of the current state of the fisheries,optimizing economic and social (employment) criteria, using maximum sustainable yield (MSY) as a goal of management, andoptimization of an ecological criterion when necessary. Optimization of current fisheries and economic and social criteria, and theMSY resulted in depletion of some stocks and in no-realistic increases in fishing effort. Combinations of economic-ecological,social-ecological and economic-social-ecological criteria did not result in stock depletion. However, some of these scenariosresulted in unrealistic choices, especially large increases in gillnet fishing effort. Among the reasonable choices, a strategy ofincreasing the hook-and-line fishery effort by a factor of 1.5 and the gillnet effort by a factor of 2.8, appeared to be potentiallyapplicable, to increase efficiency of the artisanal fisheries.
