| Abstract: | The tolerance of the black sea bass(Centropristis striata) under low salinity stress and the best timeframe of recovery after freshwater stress were studied.The results show that the half-lethal time of fish with body length of 20.32 9.67 cm is 1.63 0.23h and 0.77 0. 23h for the fish of 10.20 0.63 cm at salinity of 0,simultaneously,two sizes(20.32 9.67 cm and 10.20 0.63 cm) black sea bass can survive more than 96h under 10 salinity.Salinity acclimationextends the half-lethal time at salinity of 0.The result... |
