The aim of this study was to select the appropriate bio-indicator to monitor organochlorine contamination in the river and understand its effecting factors. Two species of fish; Spot barb (Puntius bimaculatus) and Naked catfish (Bagaridge) were selected as the representatives of herbivore fish and omnivore fish, respectively, because they were found across the country and can bear to organochlorine pesticide. Fish sample was collected from the rivers in the area of Water Resource Development Program, Sakon Naknon province, Thailand. These rivers received organochlorine pesticide from surrounding agricultural area. The results indicated that organochlorine concentration which accumulated in Spot barb was higher than that in Naked catfish. This phenomenon positively correlated to the higher amount of lipid tissue which found in Spot barb. Organochlorine pesticide is hydrophobic substance therefore it tends to be accumulated in lipid tissue. In conclusion, Spot barb can be used as a useful bio-indicator for monitoring organochlorine contamination.
