Responses of beluga (Huso huso) to salinity exposure: a laboratory evaluation of the effect of field-based salinity levels on osmoregulatory characteristics and growth performance
There is a need for a better understanding of how sturgeon, especially hatchery reared juveniles, respond to salinity challenges. Therefore, here we examined the effects of different field-based salinities (Freshwater [FW] (0.5), 3, 6, 9 and 12 ppt) on osmoregulatory characteristics and growth perfo...
