Abstract
Chlorpyrifos (CPF) is an organophosphorus insecticide which be used to control pests in agricultural fields. In this investigation, the impression of this common poison (emulsion 40.2). The rate of LC50 at 96 hours was equal to 83.2 milligram per liter and according to determined densities, it was considered some treatments with 0, 0.25, 0.50, 0.75 milligrams per liter of doresban (each with 3 repetitions) and the fish were subjected to direct densities of agricultural toxicants injections for 60 days. Then, its effect on sex hormones and gonadal quality of goldfish was investigated. Testosterone and 17-beta-estradiol levels decreased significantly in the serum of red blood cells under the influence of doresban poison significantly (P <0.05). Sperm volume, duration of sperm motility, sperm motility, sperm density, spermatocrit in treated treatments significantly decreased compared to the control group (P <0.05). Also, the gonadosomatic index in treated treatments significantly decreased compared to the control group (P <0.05). The hepatotoxicity in treated venom increased significantly compared to the control group (P <0.05). Generally, conclusions of this investigation show that increasing the amount of Doresban toxicity cause sexual hormones and gonadal quality reduction in male Carassius auratus and the most impact was related to the 0.75 ml treatment.
