Porumb Institut Roumain de Recherches Marines Constantza Abstract The author studied thoroughly the feeding conditions of young Pomatomus saltator (L. 1758), in the water layers near the Romanian littoral of the Black Sea. The researches covered several years in- cluded the qualitative and quantitative aspects of this issue. The feeding system was correlated with the size of the individuals and season. In the second part of the paper consequence of the feeding conditions on growth rate are analysed. On this occasion, some rela- tions were established and indexes determined, the value of which pointed to the link existing between feeding and individual growth.
