| Abstract | From 1988 to 1992 ichthyoplankton investigations were carried out in Guinea and Senegal, in shallow coastal and estuarine brackish or fresh waters, using a newly developed horizontal-traction fishing gear with microscopic meshes, thus allowing to collect embryonic stages of ichthyofauna (eggs), larvae and juveniles.The areas investigated include the marine shallow coastal waters of Kaloum (Conakry), Cap Vert (Dakar) and coastal rivers such as Casamance, Senegal, Fatala, Konkouré and Tabounsou Rivers, the salinity rates of which are very variable.Of the ichthyoplanktonic samples, we found common groups thet are by artisanal and industrial fisheries in West Africa, from Mauritania to Nigeria. The identification and spatio-temporal distribution of ichtyoplanktonic population have been done taking account of abiotic factors prevailing in the areas surveyed. The various larval stages were clearly specified as well as morphometric and meristic data of 15 of the 40 fish families sorted. |
