Objective The potential of underwater vehicle observations for quantitaive developments was assess, comparing them with those obtained using a still-camera, comparing density estimates obtained by underwater vehicle with those from trawling, measuring fish's reactions to the underwater vehicle. The impact of fishing on the continental slope community was assessed by comparing population density estimates for fished and unfished zones. Next, the vulnerability of different deep sea species including benthic species to fishing was assessed by studying their biology. Environmental factors other than fishing which could explain differences in population densities were sought. Relationships between species, particularly of fish and benthic organisms such as corals, was also to be studied. The cruise took place in the Bay of Biscay: Terrasse de Meriadzec (T1), Terrasse between the canyon of Saint-Nazaire Canyon of Belle-Ile (T2), Canyon of belle-Ile (T3). T1 : W 8 deg 10' - 8 deg 11', N47 deg 38' - 47 deg 43' : 1092 - 1466 m. T2 : W 4 deg 40' - 4 deg 43', N46 deg 14' - 46 deg 18' : 1122 - 1518 m. T3 : W 4 deg 39.5' - 4 deg 42', N46 deg 19' - 46 deg 21.5'.
