Abstract
   This work aimed to establish the optimal concentration of a solution of alcohol and essential oil of cloves used for anesthesia of specimens of carp Cyprinus carpio variety of Podu Iloaie nude. The biological material was divided into five experimental groups, each of which is composed of six specimens each, with a body weight of between 356.87 g and 4000.34 g. The anesthetic used in the experiment was administered in different concentrations of the oil solution of clove mixed with alcohol concentration of 99.25%. The water temperature at which investigations were conducted was located around 20°C, both in the faculty's lab and in the fish farm. During the experiments the anesthetic was used in several concentrations, varying from 0.08 ml / l to 0.5 ml / l. The solution administered was immersed in water, and the monitoring of the fish material was done at the beginning of experiments and up to a total immobilization of biological material. The effect of solution concentration alcohol and clove oil in water administered depend on a number of factors, among which the most important are: the body weight of the fish, water temperature, water concentration in the oxygen solvit and the pH of the water. The anesthetic consisting of clove oil and alcohol, is a natural product that does not cause harm to the fish and does not require the fulfillment of certain conditions for its acquisition as required for some anesthetics used in aquaculture.
