Behaviour and habitat utilisation of seven demersal fish species on the Bay of Biscay continental slope, NE Atlantic ArchiMer
Uiblein, F; Lorance, Pascal; Latrouite, Daniel.
Much is known in very broad terms about the distribution of deep-sea fishes, but information on fine-scale habitat selection and behaviour in the largest living space on earth is still rare. Based on video sequences from 4 dives performed with the manned submersible 'Nautile' at depths between 400 and 2000 in in the Bay of Biscay, NE Atlantic, we studied the behaviour of co-occurring slope-dwelling deep-sea fishes. Five different habitats were identified according to depth range or topographical and hydrological characteristics. For each fish species or genus that could be identified, estimates of absolute abundance were provided. The most frequently occurring species, round-nose grenadier Coryphaenoides rupestris, blackmouth catshark Galeus melastomus,...
