| The landing obligation implemented under the Common Fisheries Policy promoted the development of fishing gear selective devices. The REDRESSE project conducted in the Bay of Biscay was the opportunity for trawl fleets targeting cephalopods, Nephrops and demersal fish to continue to test various selective configurations to reduce their discards levels. The sea trials were carried out onboard of commercial fishing vessels and the experimental tows were sampled by an observer. Most of the selective devices were tested under the twin trawl method, with on one side the gear to be tested and on the other, the standard commercial gear. Other devices were tested with the parallel or alternate haul method. The data obtained were used to describe the catch species... |

| De nombreuses évolutions technologiques ont été mises en place en 2012, 2015 (Reg UE 737/2012 et Reg UE 2015/741) puis en 2019 et 2020 (Reg UE 2018/2034 et Reg UE 2019/2239) sur les pêcheries chalutières en mer Celtique. Dans le contexte de gestion des gadidés (cabillaud, merlan et églefin), cette étude a comme objectif de quantifier et qualifier les échappements de 3 dispositifs (110mm/PMC120mm, 100mm/PMC160mm, 120mm) par rapport à un chalut standard dont le cul a un maillage de 100mm ; engin utilisé par les chalutiers français en Zone de Protection Mer Celtique avant 2012 et qui est désormais le maillage de référence en Mer Celtique. Chacun des dispositifs a été testé en condition réelles sur différents navires entre août et octobre 2020 selon la méthode... |

| In the context of the landing obligation set by the new Common Fisheries Policy (CFP), Norway lobster Nephrops norvegicus was identified as a species likely to have high survival rate when discarded in the bottom trawl fishery of the Bay of Biscay. Previous studies in this area reported a survival rate between 30% and 51%, but the experiments were done on a limited monitoring period and the seasonal variations were not investigated. This study was designed to obtain a reliable value for survival rate after a 14-day monitoring period in onshore tanks allowing considering delayed mortality. The study also tested the effect on the survival rate of using a discarding chute system, a sorting device that was made mandatory on the 1st of January 2017 for Nephrops... |

| In the context of the reform of the Common Fishing Policy (CFP) undertaken by the European Union and implemented since 1st January 2014, the discarding of unwanted catches will gradually be forbidden. Article 15 of the CFP lays down a landing obligation for all species subject to European quotas and will come into force between 2015 and 2019 according to the species and the zones. The Regulation allows several exemptions including one for "species for which scientific proof shows high survival rates, due to the characteristics of the fishing gear, the fishing methods and the ecosystem" (EU Regulation No. 1380/2013). In particular, Nephrops were identified by the International Council for the Exploration of the Sea (ICES) as one of the species having the... |
