ABSTRACT
The study is part of a larger study of the ichthyofauna research in ROSCI0066 Danube Delta-Marine Area site, developed over several years, contributing to the development of a plan of management measures for biodiversity conservation in this area. To achieve an complete inventory of present ichthyofauna in an important site in the Natura 2000 network have been achieved scientific fishing expeditions, as required current legislation. To study the ichthyophauna has been used the method of randomized samples extracted, which is a part of the overall population and provides useful information to characterize the entire population. After species identification and performing counting measurements were analyzed class structure length, weight and age, according to a specific methodology. Fish catches have revealed greater diversity in the Sahalin area where they have been 8 fish species of which 5 with commercial importance. Sprat was in large quantities in all catches; turbot, alose and sturgeons were underrepresented. Weak representation of alose and sturgeons could be the consequence of reproduction migration. Data obtained are considered preliminary, and further research will show correctly the real situation in the ROSCI0066 Danube Delta-Marine Area site.
