European Commission Ministerio de Educación (España) Northwestern Mediterranean Trawl fishery Fishery discards Fisheries impact Deep-sea Aristeus antennatus Mediterráneo noroccidental Pesca de arrastre Descartes Impacto de la pesca Mar profundo 10 pages, 6 figures, 2 tables [EN] In this work we analysed the spatio-temporal variability of discards in the fishery of the deep-sea red shrimp Aristeus antennatus in the northwestern Mediterranean Sea. We sampled fishery discards in the fishing grounds of Palamós (the main harbour for this fishery on the Catalan margin), which are located in several areas of a submarine canyon. We found that the discard ratio in this fishery showed a marked seasonal variability, with a maximum in spring and a minimum in summer. Most of the discarded biomass (almost 96%) were of species with no commercial interest. Within these, the most represented group was elasmobranchs, making up to more than 50% of total discarded biomass. Our findings show that the landing obligation established by the EU will have a low impact in mitigating discards in this fishery, as the vast majority of discards are non-commercial species that are not specified in the regulation. Alternative management strategies, such as a temporary fishery closure in spring (when the discard ratio reaches its maximum), should be considered in order to preserve the vulnerable ecosystem hosted by the submarine canyon [ES] En este estudio se analizó la variabilidad espacio-temporal de los descartes en la pesquería de la gamba roja de profundidad Aristeus antennatus en el mar Mediterráneo Noroccidental. Para ello se muestrearon las capturas obtenidas en los caladeros de Palamós (el mayor puerto para esta pesquería en Cataluña), que están localizados en diferentes áreas adyacentes a un cañón submarino. Nuestros resultados demuestran que la proporción de descartes en las capturas de esta pesquería presenta una marcada variabilidad estacional, con un máximo en primavera y un mínimo en verano. La mayoría de la biomasa de los descartes (casi el 96%) está constituida por especies sin ningún interés comercial. Entre éstas, el grupo más representado es el de los elasmobranquios, que constituye más del 50% de la biomasa total de los descartes. Nuestros resultados indican que la obligación de desembarcar las capturas establecida por la UE tendrá un impacto bajo en disminuir los descartes en esta pesquería, ya que la gran mayoría de los descartes está constituida por especies no comerciales que no están especificadas en la regulación. Medidas de gestión alternativas, como el establecimiento de una veda en primavera (cuando la proporción de descartes llega a su máximo) deberían considerarse para preservar el ecosistema vulnerable de este cañón submarino Finally, the EC Programme Science in Society EC FP7 (grant agreements 266544-GAP2 and 287600-PERSEUS), the FPU grant of the Spanish Ministry of Education and the Marine Stewardship Council are acknowledged for their financial support Peer Reviewed 2016-03 2016-04-08T09:12:52Z artículo http://purl.org/coar/resource_type/c_6501 doi: 10.3989/scimar.04237.24A issn: 0214-8358 e-issn: 1886-8134 Scientia Marina 80(1): 79-88 (2016) http://hdl.handle.net/10261/130892 10.3989/scimar.04237.24A http://dx.doi.org/10.13039/501100000780 #PLACEHOLDER_PARENT_METADATA_VALUE# info:eu-repo/grantAgreement/EC/FP7/266544 Publisher's version http://dx.doi.org/10.3989/scimar.04237.24A Sí open Consejo Superior de Investigaciones Científicas (España) |
