- Abstract
The aim of this work was to evaluate eugenol as an anesthetic agent for hybrid patinga. Were used 60 fingerlings with an average weight of 1.08 ± 0.17 g and total length of 3.53 ± 0.15 cm. They were evaluated six different concentrations of eugenol (10, 20, 30, 40, 50, 60 mg L-1). The fish were individually exposed to anesthetic to evaluate the anesthetic induction, after the anesthesia procedure, the fish were transferred to aquaria with anesthetic free water, for observation of recovery time. Thereafter, the fish in each treatment were placed in tanks with 30 liters for monitoring the mortality during 72 hours. There was a significant difference (P <0.05) for the induction times and recovery room for different concentrations of eugenol. Mortality was observed in animals above 40 mg L-1 eugenol concentrations. It is concluded that the best concentration for the eugenol anesthesia patinga is 20 mg L-1 showed efficacy for the induction and recovery of anesthesia, without causing mortality.
