p. 183 - 210 QUELQUES OBSERVATIONS SUR LES RESULTATS DE PECHE DES CHALUTIERS ROUMAINES DANS LES EAUX DE LA REPUBLIQUE ISLAMIQUE DE MAURITANIE DURANT LA CAMPAGNE DE 1975 N.C. Papadopol et N. Jelescu Institute Roumain de Recherches Marines Constanta Abstract The authors analyses the fishing possibilities with a 2000 G.R.T. stern trawler on the basis of Romanian catches obtained in the Mauritanian waters in 1970-1972 as on the experimental cruise in 1975. The lack of periodicity, the transitive aspect between the North and the South part of the Northwest African area and some ecological unbalances are amphasised. It comes to the conclusion that for these kind of fishing vessels (more than 2000 G.R.T.) there is possible to obtain 20-30 m t/day catch on species of high economical value.
