Resumo: | 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 composition as well as their length profiles. Discards and escapement rates of both discarded and commercial fractions were also calculated. Among discards reduction and commercial size escapement, these indicators show the pros and cons of each device tested. The results per species and configuration will let the fishermen make these devices their own according to the specificities and species composition of their fisheries.
