    Beschreibung: 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.
    Beschreibung: 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.

    Beschreibung: Climate change is causing fish stocks to shift, upending the social-ecological systems that rely on the historic distributions of these stocks and creating or exacerbating fisheries conflicts. The movements of internationally shared stocks between Exclusive Economic Zones (EEZs) or between EEZs and the high seas are especially concerning because they bring into play a variety of geopolitical factors and equity issues surrounding missing or conflicting regulations of jurisdictional boundary zones. Though many studies have explored the responses to and repercussions of shifting stocks on fisheries management, there is a dearth of interdisciplinary case studies that provide insight into the complexity of conflict formation in shifting transboundary fisheries, and that highlight the initial response stages where inclusion of proactive and cooperative measures can greatly improve a system's resilience to conflict. Our study helps to fill this gap by drawing on the knowledge of a diverse group of experts to analyze four case studies where transboundary stock shifts, geopolitical or governance tensions, and uncertainty regarding the future of the marine environment collide. Through synthesis of case study findings, we create a causal model of fishery conflict, within which we highlight factors that may heighten or mitigate the risk of conflict over shifting resources such as complex histories of power imbalance, unequal access to resources, or a lack of consistent and transparent data collection. Cooperation and equitable decision-making processes are recognized as vital components of internationally shared stock management which can promote lasting, effective, and conflict-resilient fisheries.
