The effect of 1.6 mg/kg dimethoate and 0.17 mg/kg malathion treatments on gonadosomatic index (GSI) and growth performance condition (K) are presented in Figure 1 (copied without alteration from El-Gawad et al. 2011). The female GSI was significantly decreased (p<0.05) in the dimethoate treatment (0.44) compared to the control (2.15). No effect on female GSI was observed for the malathion treatment (1.11). For the male GSI, a significant decrease was observed in the dimethoate (0.34) and malathion (0.41) treatment groups compared to the control (1.03). For the K factor, no significant differences were observed for either treatment group.
