Resumen


El Mediterráneo noroccidental se enfrenta con dos realidades contrastadas: una actividad pesquera intensa y una creciente conciencia entre los ciudadanos de proteger zonas de importancia ecológica. En el noroeste de España, una gran parte del área del Cap de Creus será designada como una región Red Natura 2000 Alta Mar estableciendo así una gran Área Marina Protegida. Este estudio examina la distribución espacial de la pesca artesanal y su impacto potencial sobre componentes claves del ecosistema en vulnerabilidad (KVEC, por sus siglas en inglés). Los datos usados en este análisis provienen de encuestas basadas en cuestionarios que representan la mejor información disponible. Se ha desarrollado un mapa integrativo mostrando los valores del impacto cumulativo potencial para el Cap de Creus, incluyendo la presión de artes de pesca en los KVECs seleccionados. Las áreas potencialmente más impactadas se encontraron a lo largo de la costa y en los márgenes del cañón submarino. Los resultados mostraron que los diferentes tipos de artes de pesca convergen, lo que implica un mayor impacto en ciertas comunidades bentónicas como las zonas coralígenas, las praderas de Posidonia y los fondos de maërl que son los componentes clave del ecosistema en vulnerabilidad con mayor cobertura espacial. Cuando los datos de la bitácora y del sistema de localización de buques no están disponibles, el uso de encuestas a pescadores vinculado a sistemas de información geográficos (SIG) puede proporcionar información fundamental para aplicar medidas eficaces para la gestión del ecosistema, y mejorar así la conservación de los ecosistemas marinos bentónicos.
