The toxicity of industrial effluent from Odua Textile Mill, Ado-Ekiti on Oreochromis niloticus fingerlings was investigated. The fingerlings were exposed to increasing concentrations of the effluent in spring and pond water respectively. The mean lethal concentration (LC50) of the effluent in spring and pond water was 24.00mg/L and 31.2mg/L respectively. Mortality were significantly different (P<0.05) in the source of water used. No mortality was recorded for the control (0.00mg/L) and 12.00mg/L respectively for the spring and pond water. That indicated that fingerlings in spring water were more tolerant to industrial effluent than those in pond water.

The toxicity of industrial effluent from Odua Textile Mill, Ado-Ekiti on Oreochromis niloticus fingerlings was investigated. The fingerlings were exposed to increasing concentrations of the effluent in spring and pond water respectively. The mean lethal concentration (LC50) of the effluent in spring and pond water was 24.00mg/L and 31.2mg/L respectively. Mortality were significantly different (P<0.05) in the source of water used. No mortality was recorded for the control (0.00mg/L) and 12.00mg/L respectively for the spring and pond water. That indicated that fingerlings in spring water were more tolerant to industrial effluent than those in pond water.
