p. 261 - 273 DONNES PRELIMINAIRES CONCERNANT L'ELEVAGE DES JEUNES DE SANDRE (STIZOSTEDION LUCIOPERCA LINNE, 1758) EN MILIEU SAUMATRE I.I. Trandafirescu, Elena Ghitescu et M. Iliescu Institute Roumain de Recherches Marines Constanta Abstract The paper presents the evolution of somatic, physiological and biochemical parametres in pike-perch fingerlings, collected from natural fresh water environment and then reared under experimental conditions at different salinity concentrations. The preliminary results obtained show faster growth rate and higer rate of accumulation of proteic compounds in muscular tissue in the case of experimental groups maintained in higer salinity concentrations, comparative to control group reared in fresh water tancks.
