摘要
Recent conservation efforts have advocated for SCUBA diving ecotourism as a nonconsumptive alternative use of sharks. Although generally overlooked by conservation advocates, another nonextractive use is catch-and-release fishing, which remains poorly characterized for shark fishing. In this study, we use a combination of website content analysis and surveys of charter boat captains to assess the scale of Florida's charter boat shark fishing industry. We further examine the knowledge, attitudes, and practices of charter boat captains whose clients fish for sharks in Florida. We show that recreational charter boat shark fishing occurs throughout the state but is heavily concentrated in the Florida Keys. Shark fishing is often the most expensive trip offered, suggesting that sharks are economically important to the charter boat fishing industry. Florida's charter boat shark fishers who show a strong conservation ethic toward sharks practice catch and release commonly. Our results suggest that although some species are better candidates for catch-and-release fishing than others due to inherent physiological vulnerabilities to postrelease mortality, Florida's charter boat shark fishery can augment the recent ecotourism conservation argument that sharks may be worth more alive than dead. RESUMENactualmente, los esfuerzos de conservacion han abogado por el ecoturismo mediante buceo SCUBA como una alternativa no consumista en cuanto al uso de los tiburones. Algo que generalmente ha pasado desapercibido por los conservacionistas en cuanto al uso no extractivo de los tiburones es la pesca de captura y liberacion, la cual continua estando pobremente caracterizada para el caso de los tiburones. En este estudio se utiliza una combinacion de analisis de contenido de paginas web y sondeos a los capitanes de embarcaciones para evaluar la escala de la industria pesquera de Florida basada en botes de alquiler. Asi mismo se examina el grado de conocimiento, actitudes y practicas de los capitanes de botes de alquiler cuyos clientes pescan tiburones en Florida. Se muestra que la pesca recreativa de tiburones basada en botes de alquiler existe a lo largo de todo el estado pero se concentra principalmente en los cayos de Florida. La pesca de tiburon puede ser el viaje de pesca mas costoso que se ofrece, lo que sugiere que los tiburones son economicamente importantes para la industria pesquera basada en botes rentados. En Florida, aquellos pescadores que mostraron una mayor etica de conservacion hacia los tiburones, habitualmente practican la pesca de captura y liberacion. Los hallazgos sugieren que si bien algunas especies son mejores candidatos para la pesca de captura y liberacion debido a su inherente vulnerabilidad fisiologica a la mortalidad que ocurre tras la liberacion, la pesqueria de tiburones en Florida basada en botes rentados puede abonar al argumento de la conservacion ecoturistica de que los tiburones valen mas vivos que muertos.
