The present study examined the acute toxicity of organophosphate pesticides (methyl parathion, chlorpyrifos) and synthetic pyrethroid pesticides (fenvalerate, fenpropathrin) to shrimp juveniles (Metapenaeus monoceros Fabricius, 1798). The 24 h LCso for penaeid shrimp juvenile was 0.1, 1.3, 0.65 and 0.26 ppb for chlorpyrifos, methyl parathion, fenvalerate and fenpropathrin, respectively. This high sensitivity of juveniles to pesticides is alarming as it may have implications on the fishery industries which play a significant role in the national economy and towards the food security of the country.
