The Toxicity of Imidacloprid on Early Embryonic Stages and Growth Rate of Hatchlings of Common Carp, Cyprinus carpio

In the present investigation, the toxicity of imidacloprid was tested on the embryos (fertilized eggs) and hatchlings of Cyprinus carpio in terms of mortality (%), hatching success (%) and abnormal/malformed hatchling along with their growth performance in toxicant medium. Reported data from acute toxicity tests of imidacloprid was statistically analyzed by Probit Analysis Method and 48 h (hour) LC50 was reported as 78 ppm for embryos of C. carpio. Three sublethal doses of imidacloprid i.e., 7.8 ppm (T1), 15.6 ppm (T2) and 23.4 ppm (T2), were selected for further experimentation along with control. The findings revealed that mortality of exposed eggs (%) was significantly (p
