Grass carp acclimated to 3, 5, 7, and 9% salinities were tested for salinity tolerance. The upper tolerance limit (LS 50 ) for 3 and 5%, and 7% acclimated fish were 14.2 and 14.0%, respectively. Fish acclimated to 9% had a 50% mortality at an estimated salinity of 16.0%, for 24 h exposure. Weight losses for the 3 and 5% acclimated fish were significantly lower than for those acclimated to 9%.
