The initial mean wet weight of the test fish were 7.64:~c 1.3 for the control and 6.33~c 0.9, 6.88~c 0.9 and 6.2~c 0.7 for the fish exposed to 1.02, 1.40 and 2.0mg/l of paraquat in water respectively. Growth was estimated from the sum of the individual wet weights of the fish at 2, 4, 6 and 8 weeks of exposure to the toxicant and expressed as percent Cumulative wet weight gain. The results showed that the cumulative percent wet weight gain in the control group increased from 10.34% at 1 week to 36.13% at 8 weeks. The growth of fish that were exposed to 1.02, 1.04 and 2.00mg/l increased from 3%, 0.44% and 1.55% at 1 week to 30.81 %, 9.59% and 19.81 % at week 8 respectively. A statistically significant difference in growth rate of the treated and control was observed (p〈0.05).
