Resumen

Este estudio analiza la dinámica de la flota pesquera en las Islas Cíes, localizadas en el Parque Nacional marítimoterrestre de Galicia. Por medio de entrevistas a pescadores hemos identificado la flota en la zona de estudio y hemos obtenido datos temporales de esfuerzo y capturas. A continuación hemos llevado a cabo un análisis multivariante de los perfiles de capturas para identificar las estrategias de pesca y su dinámica temporal. Nuestros resultados resaltan la complejidad del sistema pesquero, compuesto por 565 barcos que usan 19 artes y 33 estrategias de pesca diferentes en un área de 26.6 km2. Las estrategias de pesca más usadas son nasas de pulpo y nécora, arte de enmalle fijo dirigido a la captura de pescadilla, trasmallos dirigidos a la pesca de centolla y maragota, rastros para almeja, y recolección manual de percebe y navaja. Cabe decir también que la mayoría de los barcos son generalistas y utilizan hasta 7 estrategias diferentes a lo largo del año. Esta flexibilidad de la flota para cambiar su especie objetivo genera una amplia diversidad de patrones anuales de pesca que todavía incrementan más la complejidad del sistema y la dificultad para gestionarlo. La implementación de programas de recogida de datos que incluyan la dinámica de la flota y datos espaciales son clave para desarrollar unas regulaciones de gestión efectivas y consistentes con la complejidad del sistema.
