بررسي امكان بيهوشي ماهي كپور معمولي CYPRINUS CARPIO با داروي كتامين و گزيلازين

Using ketamine and xylazine hydrochloride for anaesthesia of common carp (Cyprlnus carpio).

The possibility of using ketamine hydrochloride and combination of ketamine and xylazine hydrochloride were studied in common carp. The study were carried out on about 300 carps weighting 10-30 grams, in 24-26c water temperature, ketamine dissoved in water at different concentration (15: 200 mg/l). Ec50 and Lc50 in 1 5 min. for this drug were 35 and 1 70 mg/l respectively. For using ketamine and xylazine in combination, the fishes were placed in a solution of 15 mg/l xylazine for 15 minutes as a pre anaesthetic agent, then in different concentrations of ketamine (20-250 mg/l), in 1 min. In this situation, Ec50 and Lc50 for ketamine were 36.3 and 230 mg/l respectively as the result ketamine and combination of ketamine and xylazine could be used as an immobilization and anaesthetic agent in common carp but for their commercial use research need to do further research.
