Fish biodiversity is a key indicator of the health of a waterbody and the structure and function of fish communities are considered good indicators of the ecological status of marine ecosystems. Therefore, the long-term assessment and the development of predictions regarding the size and productive capacity of fish populations are necessary, aiming at ensuring an ecosystem-based management of living resources. In the frame of the revision of the Danube Delta Biosphere Reserve Management Plan, an updated evaluation of fish species present in the marine zone (ROSCI0066) was performed. The scientific fishing (by survey trawling and gillnetting) revealed a rich ichthyofauna: 32 taxa, belonging to 21 families were identified. The species array is diverse, including both economically important fish (turbot, shads, anchovy, sprat) and species of high conservative interest (sturgeons), emphasizing the crucial importance of this area as feeding and spawning ground of Black Sea ichthyofauna.
