The trawlfauna of the Mauritanian shelf (Northwest Africa): density, species composition, and biomaof the invertebrates and demersal fish were analysed. On the basis of species abundances, three station groups could be distinguished each corresponding to a subregion of the shelf: an inner shelf, a midshelf and an outer shelf station group. The average depth increased from 20 m for the inner to mo

,The distribution and abundance of young fish in the Banc d’Arguin, Mauritania,wl at 50 locations in the coastal zone between Cap Sainte Anne and Cap Timiris. Water depth varied between 1 and 16 metres. Temperature and salinity at each station have been measured, as well as the weight of the catch and total length of the individual fish. The largest catches — in numbers as wel

,Seabirds in the shelf edge waters bordering the Banc d’Arguin, Mauritania, in May,itidae), were the most numerous with an average density of 14.5 km.. They were most abundant over water-patches rich in primary production or Zooplankton, but the simultaneous presence of trawlers in these areas made it impossible to relate seabird density directly to hydrography. The trawlers attra
