Climate change calls for the diversification of aquaculture species, seeking alternatives tolerating warmer summer temperatures. In this context, the research on the adaptability of gilthead seabream Sparus aurata (Linnaeus, 1758) for Romanian marine aquaculture was performed. The experiment demonstrated the possibility of transferring three months old juveniles from a 36‰ salinity into Black Sea water (mean salinity 15‰), without any mortality. The evolution of the stress induced by the difference in salinity was carefully monitored. Glycemic levels between 68-82 mg/dl before, 157-171 mg/dl one hour after the sudden change in salinity and 115-124 mg/dl at 24 hours were documented, respectively. Corroborated with the color changes and the resumption of active feeding and schooling behavior, it can be inferred that the use of the species is feasible in Romania. An average biomass increase comparable to relevant literature was documented: from seven grams initially to 300 grams. The biochemical analysis of the meat also revealed a balanced composition. Overall, S. aurata proved a viable candidate for Western Black Sea cage aquaculture in a rotational system, complementary to colder water species.
