SALINITY TOLERANCE OF CLARIAS BATRACHUS

摘要

In order to comprehend the tolerance limits of Clarias batrachus to salinity variations, laboratory tests were conducted at 20 salinity levels ranging from 0.5 to 30 ppt. The results indicate that upto 12.0‰ salinity, all individuals survived and at 13.0‰ they died within 30 hours. With the increase in the salinity concentrations, the time required for complete kill was also reduced being only 0.50 h at 30.0‰ salinity.
