Des la seconde moitie du XIXe siecle, de nombreux navires oceanographiques ont prospecte les cotes nord-ouest africaines, mais ils ne l'ont fait qu'en passant. Leur principale zone de recherche etait plus etendue ou plus eloignee des cotes europeennes. Dans ces conditions, le domaine des connaissances est reste longtemps limite, dans cette region, aux eaux peu profondes. Il y a une dizaine d'annees encore les documents traitant de l'ecologie et de la nature des fonds de plus de 200 m etaient…

The thornback ray, Raja clavata L., 1758 presented a wide distribution in the Atlantic Ocean and the Mediterranean Sea. The species was reported in northern waters of eastern Atlantic, from
Change in Elasmobranchs and Other IncidentalSpecies in the Spanish Deepwater Black HakeTrawl Fishery off Mauritania (1992–2001)
It is believed that the decline in by-catch from the Spanish deepwater trawl fishery for black hake off Mauritania could be due to a set of different factors: a change in depths fished, economic reasons and probable over-exploitation of both targeted species and by- catch.
The angular rough shark Oxynotus centrina (Linnaeus, 1758) is reported in the eastern Atlantic from the British Isles (Wheeler 1969) to southern Portugal (Albuquerque 1954-1956), and south of the Strait of Gibraltar to Sen-

Species diversity of the deep‐water gulper sharks (Squaliformes: Centrophoridae: Centrophorus) in North Atlantic waters – current status and taxonomic issues
Five groups of deep-water benthopelagic sharks identified in the North Atlantic also occur in the Indian and/or Pacific Oceans, thus extending the reported range of some species considerably.
Demersal Ichthyofaunal Assemblages in Mauritanian Deep-Waters
A total of 2.7 million individuals and 191 tons of demersal fishes were caught at 283 trawling stations in Mauritanian waters, from 80 to 1860-m depth, during four scientific surveys. We identified
Capture of a rare shark, Oxynotus centrina (Chondrichthyes: Oxynotidae) in the eastern Adriatic Sea
Examination of the stomach did not reveal traces of any recently eaten or even partly digested food, suggesting that the female was in a non-feeding period, and confirms that vitellogenesis does not proceed in parallel with gestation and that the species reproduces in alternate years.
