AB  - A static bioassay was conducted to determine the 96h LC50 of NaCl to <I>Oreochromis niloticus</I> fingerlings (11.58 +<I> </I>0.13 g) and to describe the histological changes in the gill, heart and kidney. LC50 of <I>O. niloticus </I>fingerlings was determined graphically as 11.33ppt. The fish showed increase hyperactivity exemplified by erratic movement, loss of reflex and hyperventilation during 96 h exposure. Histological examination revealed that gill architecture was destroyed and gill lamellae were fused. The heart showed deformities including perforation and enlargement. The kidney was greatly deformed and discoloured.
