Evaluation of Clove (Eugenia caryophyllata) and Tobacco (Nicotiana tabacum) powders for common carp Cyprinus carpio L. anesthesia

The anesthetic efficacy of two kinds of natural anesthetic Clove (Eugenia caryophyllatata) and Tobacco (Nicotiana tabacum) powders were evaluated on common carp (Cyprinus carpio L.) for handling and health management experiments. The concentrations of anesthetics were assessed by using two types of clove and tobacco anesthetics; each with three replicates for measuring induction times to anesthesia. Concentrations of 100, 200, 250, and 350 mg/l at the ratio 1:1 of the aqueous extract of both Clove (Eugenia caryophyllatata) and Tobacco (Nicotiana tabacum) to evaluate their effect on common carp anesthesia were used. The aqueous extract anesthetized fish partially in the high levels. No significant differences appeared on blood glucose, ALP, ALT and AST among different levels of the anesthesia concentrations used. As the anesthesia concentration increased, the Red blood cell (RBC) count and hemoglobin decreased.
