Worldwide, it is recognized and appreciated the significant role it has continental and marine fisheries, and aquaculture, both by contributing to food supplies and the economic and social well-being of populations worldwide. Evolution of main species of fish catches from the Romanian marine waters was obtained by centralizing and systematizing in time, catch and effort data obtained from the profile companies. Data analysis was performed for the period 1950-2009. Depending on the status of fish populations, fishing effort applied and the type of tool used, the Romanian seaside catches had a variable evolution of the structure of qualitative and quantitative. Usually the Black Sea ichthyofauna and in particular populations of commercial interest in recent decades have witnessed severe mutations and often unpredictable. Fish fauna from the Romanian coast includes, potentially, over 142 species and subspecies. Many fish populations have declined so rapidly that they have lost importance in commercial fisheries, marine ichthyofauna only remaining representatives of zoological species. During the period 1960 _ 1970 there were 26 commercial species of fish; now their number has gradually decreased, remaining at present about ten pelagic species with commercial importance, all three small-sized demersal species.
