Newborn guppies, both males and females, showed an increase in

the HSI during exposure compared to controls. No effect on weight, length, or HIS was observed for either inorganic or methylmercury exposures. Some wetland field sites showed a reduction in the HSI of fish; the gonadal somatic index (GSI) response was not the same as the HIS, as only one site showed a reduction in GSI. Liver selenium levels were inversely correlated with the HSI in both male and female fish. The GSI was higher in fish of both sexes from c
