Comparison of anesthesia effect of electric shock, CO2, and clove powder on physiological parameters in Acipensernudiventris

The present study was carried out to investigate the anesthesia effect of three anesthetics, electric shock, CO2, and clove powder, andcomparison of physiological parameters in Acipenser nudiventris with an average weight of 79.38 gr. In this study, the electric shock with the voltage of 130 v, 225 mmHg for CO2, and 40 gr for clove powder were used. Considering to anesthesia and recovery time, electric shock (induction time 0.15 min, and recovery time 3.23 min) was selected as the best anesthetic compared to CO2, and clove powder. The lowest change in biochemical parameters was observed for clove powder, subsequently electric shock and CO2. Over all, considering appropriate efficacy of electric shock in both induction and recovery times, and have the low changes in biochemical indices, it would be recommended for this species and other Acipenserids during aquaculture practices.
