| A fisrt survey designed to estimate the impact of the fishery on the multispecific population of the slope has been carried out from June 26th to July 20th 1996 on board of the French R/V Thalassa. This survey took place West of Scotland, between 55 degrees and 57 degrees of latitude North, on an area from where data before exploitation were available and where fishing activity was intensive since the 90's. On this area, the analysis of the species composition by haul only showed that the fish assemblage was structured according to depth. Such a conclusion was not new. However, the positioning of the hauls on two smaller sectors characterized by different slopes and bottoms, and probably by a lesser fishing intensity on the one with rougher bottom did not... |
