12 pages, 5 figures, 4 tables[EN] Fishing in the Medes Islands Marine Reserve (511 ha, including a no-take zone and a buffer area) was prohibited in 1983. This study is the result of a 2.5-year monitoring program (sampling on board fishing boats from June 2003 to December 2005) aimed at characterizing the small-scale fishing carried out near the reserve. A total of 109 species were identified. The various métiers in use with the fishing gears trammel net, longline and gillnet were identified on the basis of the landing profiles. The main fishing target species included striped red mullet (Mullus surmuletus), common sole (Solea solea), gilthead seabream (Sparus aurata), common cuttlefish (Sepia officinalis), common pandora (Pagellus erythrinus), seabass (Dicentrarchus labrax), spiny lobster (Palinurus elephas) and hake (Merluccius merluccius). Most of the catches consisted of mature individuals and discards were very low or nil. The exception was Palinurus elephas, with catches made up mostly of juveniles. The estimated stock parameters for Mullus surmuletus, Pagellus erythrinus, Sparus aurata and Scorpaena porcus (Lc mean catch length; Lopt length at maximum yield per recruit; Y/Rc; Y/Rmax; Y/R at F(0.1), Y/R(0.1)) and the distributions of the exploited sizes, with presence of very large individuals, suggest a situation of low fishing pressure[ES] En 1983 se prohibió la pesca en la reserva marina de las Islas Medes (511 ha, con una zona estrictamente protegida y una zona parcialmente protegida). Este estudio es el resultado de un programa de seguimiento (muestreo a bordo de barcas de pesca desde junio de 2003 a diciembre de 2005) para la caracterización de la pesca artesanal realizada cerca de la reserva. Fueron identificadas un total de 109 especies. En base a los perfiles de captura y para trasmallo, palangre y beta, se identificaron los distintos métiers en uso. Las principales especies objetivo de la pesca incluyeron el salmonete de roca (Mullus surmuletus), lenguado (Solea solea), dorada (Sparus aurata), sepia (Sepia officinalis), breca (Pagellus erythrinus), lubina (Dicentrarchus labrax), langosta (Palinurus elephas), merluza (Merluccius merluccius). La mayor parte de la captura estuvo constituida por ejemplares maduros y los descartes fueron muy bajos o inexistentes. La excepción fue Palinurus elephas, con capturas constituidas mayoritariamente por juveniles. Los parámetros estimados para los stocks de Mullus surmuletus, Pagellus erythrinus, Sparus aurata y Scorpaena porcus (Lc talla media de captura; Lopt longitud en el máximo rendimiento por recluta; Y/Rc; Y/Rmax; Y/R a F(0.1), Y/R(0.1)) y las distribuciones de tallas explotadas, con presencia de ejemplares de gran tamaño, sugieren una situación de baja presión pesqueraThe study was partially funded by the European Commission research projects BIOMEX (QLRT-2001-00891) and EMPAFISH (STREP/006539)Peer reviewe
