A multi-institutional approach for modeling the bioeconomic profit of fisheries management approaches in Cuba.Abstract
La biodiversidad de los ecosistemas marino-costeros de Cuba sostiene altos niveles de actividad pesquera. Debido en parte a la fuerte presión pesquera, administradores y científicos reconocen signos de sobrepesca para muchos stocks, intensificados por crecientes tasas de turismo y desarrollo costero. Estos factores amenazan la salud de esos ecosistemas y ponen en peligro el futuro económico y los medios de vida de comunidades costeras y la industria pesquera. Se eligieron nueve stocks dada su importancia en la captura total, valor económico, diversas historias de vida y susceptibilidad a la sobrepesca. Se usó un modelo dependiente solo de captura (COM), Catch-MSY, para evaluar su estado actual. Se encontró que todas las poblaciones están agotadas y que ocho experimentan sobrepesca. Luego, se utilizó un modelo bioeconómico para obtener estimaciones futuras de captura, ganancias y biomasa bajo diversas estrategias de manejo para lograr diferentes objetivos de producción y conservación. El modelo se adaptó al contexto cubano con información local, estimaciones específicas de precios y costos, así como estimaciones de mortalidad por pesca atribuida a la pesca ilegal. Las proyecciones a 50 años muestran potencial para aumentar biomasa y ganancias disminuyendo las capturas. Manteniendo la estrategia actual, sin incentivos económicos y con pesca ilegal, se observó que la biomasa, las ganancias y las capturas disminuyen. Para cada especie individualmente se mostraron resultados más diversos, aunque para la mayoría parece posible mejorar la situación actual. Los resultados muestran oportunidades de recuperación y ayudarán a determinar el potencial de pesquerías multiespecíficas aplicando reformas de manejo sostenible.Biodiversity of marine-coastal ecosystems of Cuba sustains high levels of fishing activity. Due in part to heavy fishing pressure, managers and scientists recognize signs of overfishing for many stocks, intensified by increasing rates of tourism and coastal development. These factors threaten the health of those ecosystems and jeopardize the economic future and livelihoods of coastal communities and the fishing industry. Nine stocks were chosen because of their importance in total catch, economic value, a variety of life histories and susceptibility to overfishing. A model depending only on total fishing (COM). Catch-MSY was used to evaluate the current stock status. All the stocks were found to be overfished and eight were found to be experiencing overfishing. Then; a bioeconomic model was used to provide future estimates of fishing, profits, and biomass under various fishery management strategies that aimed to achieve different production and conservation goals. The model was tailored to the Cuban context with local information, local and specific estimates of prices and costs, and estimates of fishing mortality attributed to illegal fishing. 50-year projections show potential for increasing biomass and profits with decreasing fishing. By maintaining the current strategy without economic incentives and with illegal fishing it was observed that biomass, profits and fishing decrease. For each species individually the results were more diverse, although for most it seems possible to improve the current situation. The results show recovery opportunities and will help to map out the potential of multi-specific fisheries with the application of sustainable management reforms.
