Abstract: Pesticides introduced into aquatic ecosystems can effect on fish health in various ways. Pesticides impair various metabolic and physiological functions within fish organisms the use of pesticides results in lethal toxicity that can lead to mutagenesis, carcinogenesis, haematological alterations, histopathological issues, variations in the endocrine system, and reproductive abnormalities. The introduction of these chemicals into aquatic ecosystems occurs primarily through surface runoff and drainage, resulting in various reproductive issues in fish. These substances can impact the spinal cords of fish, leading to spinal deformities, and cause histopathological changes in the gills, liver, spleen, kidneys, and brain, ultimately reducing fish metabolism. Pesticides into fish bodies leads to various complications in gills, including haemorrhage, clubbed lamellae, damage to gill rakers, and enlargement of gill filaments. Histopathological alterations resulting from pesticide exposure include collapsed, disorganized, and fused lamellae, as well as haemorrhage, necrosis, blood coagulation, and increased mucous secretion]. Pesticides totally effect different organs, causes histological and haematological changes.
