Romanian marine aquaculture is a recent development, as a consequence of both harsh environmental conditions and a cumbersome legislative framework. The much-awaited settlement of the water concession opened the way for this activity. After the successful testing of rainbow trout Oncorhynchus mykiss (Walbaum, 1792) and gilthead seabream Sparus aurata (Linnaeus, 1758), this research aimed at investigating the potential of European seabass Dicentrarchus labrax (Linnaeus, 1758) for culture under Black Sea conditions. The laboratory experiment demonstrated the possibility of transferring 4-months old juveniles from a salinity of 35‰ directly into brackish water (salinity 15‰), with no mortalities and rapid post-stress recovery (24 hours after transfer glycaemia levels returned to normal, with a mean value of 78 mg·dL-1). A control batch was kept at the original 35‰ salinity. Biomass increase was normal, from 7-8 grams initially to 300 g after nine months (during autumn-winter), with no significant differences between salinities. The species proved its suitability for culture at the Romanian coast especially due to its wide temperature range tolerance, being able to feed and grow during colder Black Sea winters.
