Abstract

Deltamethrin, a synthetic pyrethroid insecticide contaminating aquatic ecosystem as a potential toxic pollutant is under investigation in the present study of chronic toxicity. Bony fishes were selected for the bioassay experiment. The 96hr LC50 value, behavioural assessment post treatment and evaluation of stress parameters by studying the histopathology of the fish tissues were the primary components of the study. For the experimental setup, a commonly available teleost fish, Common Molly Poecilia sphenops (Valenciennes, 1846) was obtained and kept in well aerated aquarium tanks for a period of 7 days to acclimatize. The water parameters like pH, temperature and dissolved oxygen were regularly checked and observed every day. Fishes were divided in groups (low concentration, medium concentration, high concentration and control group). We recorded a continuous observation of changes in fish behaviour after giving different dose of deltamethrin. After exposure of the different concentrations of deltamethrin, random samples were collected from the each of the group and were sacrificed for their regular histo-pathological studies for gills and muscles.
