EFFECTS OF LOW DOSES OF LAMBDA CYHALOTHRIN ON HEMATOBIOCHEMICAL REACTIONS OF NILE TILAPIA

Abstract

Lambda Cyhalothrin is a synthetic pesticide that is used to kill nematodes and insects in agricultural crops. It is a major contaminant polluting aquatic ecosystems, having a harmful effecting health of fish; therefore, the current experiment was performed to assess the effects of low doses of Lambda Cyhalothrin on the hematobiochemical reactions of Nile Tilapia. In order to do this, fish were obtained from a fish farm in the area and then separated into three separate groups (A, B, and C). While group A served as a control, groups B as well as C were given two doses of Lambda Cyhalothrin (0.01 mg/L and 0.04 mg/L) that were below the threshold of being deadly over a period of 28 days. The LC50 value determined by probit analysis was 0.103 mg/L. Fish were provided a normal feed each day based on their body weight. The findings of the current study showed that concentrations of triglycerides, VLDL, ALT, AST, cholesterol,  blood glucose, serum creatinine, WBCs, PLT, MPV, neutrophils, lymphocytes, and monocytes increased while the results of total protein, albumin, globulin, urea, HGB, RBCs, HCT, LDL, HDL, MCHC, PDW, MCH, PCT, serum BUN (blood urea nitrogen), and MCV, T3 (triiodothyronine hormones), and T4 (thyroxin hormone) levels significantly decreased when comparing the experimental groups to the pesticide-free group. According to current research, Nile Tilapia fingerlings exposed to lambda experience changes in their biochemical and haematology parameters.
