Abstract
Pyriproxyfen and Acetamiprid are insecticides, extensively used to eradicate insects. The current investigation was carried out to ascertain the physiological dysfunctions as consequences of Acetamiprid and Pyriproxyfen exposure in fish Freshwater carp. For this purpose 27 Bighead carp were brought from Bahawalnagar hatchery and divided into three groups G0, G1 and G2, fish were acclimatized for 15 days before experiment. Acetamiprid and Pyriproxyfen were applied together with different concentrations, 0, 2 and 3 mg/L in group G0, G1 and G2 respectively. After administration of chemical, different clinical signs such as; bottom running, surface running, gasping, operculum movement, reversed tilting of pectoral fin, convulsions, jerking, surface breathing, unbalanced body movements, static position, and faintness were observed in fish at day 7 and 14. Dissection of fish was performed at equal intervals of day 7 and 14. Additionally, physiological dysfunctions such as reduction in body weight, reduced growth, and malfunctioning of the visceral organs were recorded during study. In group G2 in which high concentration was applied, fish showed perceptible physiological dysfunctions and other clinical signs. While the group in which low concentration was provided physiological dysfunctions comparatively was minor, but other clinical signs were recognizable in group G1. Results revealed that the toxicity of Pyriproxyfen and Acetamiprid disrupted the body weight of fish.
