Abstract– The use of pesticides in agricultural practices has raised concerns about their impact on aquatic ecosystems, including the health of aquatic organisms such as fish. Imidacloprid, a widely utilized neonicotinoid insecticide, has garnered substantial attention due to its potential environmental implications. This review delves into the multifaceted effects of Imidacloprid on the biochemical and hematological parameters of Cirrhinus mrigala, a prominent freshwater fish species. The aquatic ecosystem’s delicate balance is significantly impacted by the widespread use of this pesticide in agriculture. As such, understanding its effects on aquatic organisms, such as Cirrhinus mrigala, is paramount. We discuss the various routes through which Imidacloprid infiltrates aquatic ecosystems, highlighting its sources and its persistence in water bodies. Imidacloprid’s presence in these environments exposes aquatic organisms to a spectrum of toxicological challenges. Subsequently scrutinize the specific effects on biochemical and hematological parameters. Biochemically, Imidacloprid exposure disrupts enzyme activity, notably acetylcholinesterase, and induces oxidative stress through lipid peroxidation and altered antioxidant enzyme levels. Imidacloprid also impacts metabolic parameters, such as glucose levels, and leads to histopathological changes in fish tissues. Hematologically, the insecticide results in deviations in hematocrit and hemoglobin levels, alterations in red and white blood cell counts, and changes in erythrocyte morphology. The review further probes into the broader ecological consequences of Imidacloprid contamination. This entails effects on fish populations, disruptions in food chains, and potential consequences for ecosystem health. In summary, this comprehensive review underscores the need for a deeper understanding of the effects of Imidacloprid on biochemical and hematological parameters in Cirrhinus mrigala. The intricate web of interactions between this pesticide and fish health, coupled with its broader ecological ramifications, highlights the importance of responsible pesticide management in safeguarding aquatic ecosystems and the organisms that inhabit them.
