Resumo: | On the French Mediterranean coasts, trawl fishing used to be practiced exclusively with two-sided nets until the middle of the 1970s. The adoption of four-sided trawls has changed the composition of species and sizes of the trawlers'catches in this area. Experimental fisheries conducted in the Gulf of Lion on board a research vessel belonging to the IFREMER enabled the study of the selectivity parameters of a four-sided bottom trawl with a wrapping double-pocket. Three pockets of different meshes were tried out on various demersal and pelagic species. The collected data was processed through different selectivity analysis methods. Presented here is an assessment of the relative efficiency of each of these seven methods.
