    Abstract: About 100% mortality was recorded in hybrid catfish fingerlings that were exposed to 10 and 12 ppt at the 3rd and 12th h, respectively. Those in 6 and 8 ppt had 90 and 25% survival, respectively at the end of 96 h. Median Lethal Salinity (MLS<SUB>96</SUB>) for 10 ppt was 5.55 h. The cumulative mortality at the various salinity concentrations did not differ in 4 and 6 ppt but differed in 8, 10 and 12 not differ from 12-48 h and between 72 and 96 h (p&gt;0.05). Water temperature values ranged from 26.0&deg;C, dissolved oxygen ranged from 5.2 mg c<SUP>-1</SUP> to 6.8 mg L<SUP>-1</SUP> while pH ranged from 5.2-6.6.
