Abstract—Oil contamination causes morphological, cytological and behavioral abnormalities in fish. This study was undertaken to evaluate the short-term exposure effect of the mixture of grease and engine wash oil on Pangasius sutchi. Fishes exposed to the mixtures of grease and engine wash oil showed various behavioral patterns depending on the amount of doses and exposure time. The test fishes showed different behavioral signs like restlessness, continuous discomfort in swimming, jumping, jerky movement, frequent surfacing, opening and closing operculum, mouth and loss of equilibrium at the final stage. The changes in the mortality of Pangasius sutchi was observed at various exposure periods, i.e., 24, 48, 72 and 96 hrs respectively. The higher exposure period revealed higher percentage of mortality and it was further intensified at higher concentrations. At the concentrations of 3.0 ml/L, 3.5 ml/L, 4.0 ml/L and 4.5 ml/L, the mortality rate found for this fish for 24 h and 48 h were 0%, 0%, 10%, 20% and 0%, 20%, 30%, 40% respectively, while at the same concentrations the mortality rate of 72 and 96 h were 10%, 30%, 50%, 60% and 20%, 50%, 70%, 90% respectively. In this study a statistical software EPA probit analysis was used to find out the effective dose. The lethal concentrations (LC 50 values) of 24 h and 48 h were 5.10 ml/L and 4.65 ml/L respectively, while the LC 50 values of 72 and 96 h were 4.10 ml/L and 3.54 ml/L respectively. The values of LC 1 , LC 5 , LC 10 , LC 15 , LC 50 , LC 85 , LC 90 , LC 95 and LC 99 varied inversely with the increase of exposure time. This contribution provides valuable information about the lethal concentration of oil and shows that as the exposure time increases the toxicity also increases.
