Abstract
For an anesthetic is used efficiently it is important to establish your concentration and the ideal exposure time, thus the present study sought to identify the concentration of anesthetic eugenol most appropriate to be used in stunning of juvenile mollies Mollienesia sp. by dipping baths and times necessary to achieve the level of deep anesthesia and recovery. Using a digital timer was carried out at timing of the time required for anesthesia and recovery biometrics mollies 10 in each of the five concentrations of the anesthetic eugenol (10, 20, 30, 40 and 50 mg L-1) tested. In relation to the biometric time and recovery time statistically significant difference was observed among the five concentrations tested. The treatment that used the concentration of eugenol of 10 mg L-1 had a higher average anesthesia time (315.1 ± 130s) compared to other treatments. The treatments used 20, 30, 40 and 50 mg L-1 obtained results 119.8 ± 25.9s; 116.9 ± 33s; 93.3 ± 33.7s and 62.3 ± 10.2s respectively. Not suitable use of eugenol in a concentration of 10 mg L-1, because the anesthesia induction time is too long. The remaining concentrations used showed results within the standards suggested by the literature, however the concentrations of 30 and 40 mg L-1 were safer because it is not observed mortality within 96 hours. It is recommended that the concentration of 30mg L-1 for the anesthesia of Molly juveniles.
