Contamination of aquatic
environment with pesticides via rainfall runoff is very
possible [18]. Fishes are sensitive to aquatic
contamination, although the sensitivity of Pangasius spp.
found to be lower than other species [1].Serious concerns
remains due to their potential to cause adverse effects on
human and wildlife populations. In addition we found that
both diazinon and deltamethrin are lethal substrates to
P. Hypop hthalmus.
