Resumo: | Data on the potential exploitation of deep demersal fish species in Reunion Island are very limited. The Regional Comitee for Sea Fisheries and Marine Breeding, with the scientific and technical support of Ifremer of La Reunion, has launched prospecting campaigns to identify and characterize deep-sea fish species (between 150 to 600 m deep), with an innovative method of catching with electric reel. The catches made concern mainly 5 main species (yields, frequency of catch, commercial interest). A new species, the brillant pomfret (Eumegistus illustris), as well as the longtail red snapper (Etelis coruscans), are the both main resources that can be exploited by the electric reel technique. They represent more than 60% of the overall catches made during the survey. The other species (red snapper (Etelis carbunculus), shortnose spurdog (Squalus megalops), beryx (Beryx decadactylus),  black snoek (Thyrsitoides marleyi)) are supplements species, given the impossibility to target them, and maintain daily yields at a consistent level with the profitability of the fishing operation. The distribution of these species is strongly related to bathymetry and an assessment of the area available for their habitat around the island, shows that the abundance of these resources is limited to an incompatible level with intensive exploitation. Absence of more precise scientific arguments suggest a precautionary approach and encourages to recommend not favoring the exploitation of new efficient fishing units on this resource but rather to consider it as a potential complementary activity for the fishing units of current small professional fishery, which practice other trades (coral fish species and pelagic fish on FADs with fishing hook).
