Impact of Sublethal Concentration of Detergents on Serum Biochemical Constituents of Freshwater Fish, Mystus vittatus (Bloch)

Abstract

The 96 hours median lethal concentration (LC₅₀) of Tide detergent for Mystus vittatus by using probit analysis software (SPSS version 26) at 95% confidence limit was 17.981 mg/L. The current study has been carried out to investigate the impact of sublethal concentrations (4.5 mg/L or 1/4^th and 9.0 mg/L or 1/2^th of 96h LC₅₀) of detergent Tide on the serum biochemical constituents of Mystus vittatus after exposure to 7, 14, 21 and 28 days. The present study indicates a significant decrease in serum metabolites, including glucose and total protein, while triglyceride levels showed a significant increase. From the result of one way ANOVA analysis it was observed that the sublethal lethal concentrations were highly influenced the serum biochemical contents of fishes. The Post hoc test (Tukey) revealed that the serum glucose, serum total protein and serum triglyceride contents were altered with both sublethal concentrations of detergents and period of exposure. Thus, the results of this investigation provide an indication of how the fish Mystus vittatus can be used as a bioindicator for chemical pollution through alterations in biochemical parameters.
