p. 31 - 44 INFLUENCE DES CONDITIONS DE L'ENVIRONNEMENT SUR LA MIGRATION DES POISSONS PELAGIQUES DANS LA ZONE DE FAIBLE PROFONDEUR (BAIE DE MAMAIA) PENDANT L'ANNEE 1992 S. Nicolaev, G. Radu, N. Bodeanu, Gina Butoi, Florica Verioti Angela Butu, Aurica Gorban, Adriana Petran, Lucia Popa Institut Roumain de Recherches Marines Constanta Abstract The studies carried out in 1992 in the shallow waters of Mamaia Bay showed that the spacial and temporal distributions of fish populations are directly dependent either on the abiotic conditions specific for that year and on the food abundance. A characteristic of 1992 as well as of the last years is the concentration of the stationary fishery catches in the first months of the fishing season; those catches include mainly sprat and Black Sea whiting and additionally dogfish, anchovy, Black Sea alosa, atherinid, kilka. The biochemical determinations showed the sprat and anchovy have high alimentary value in summer months and the kilka is a fish with low alimentary value.
