ALVAREZ-PERDOMO, Natalia et al. Eugenol as an anesthetic for the handling of juvenile fingerlings of Pavon (Cichla orinocensis). Orinoquia [online]. 2016, vol.20, n.2, pp.30-33. ISSN 0121-3709.

In order to establish an optimal concentration of anesthetic eugenol for proper handling of juvenile Pavon (Cichla orinocensis), 24 juveniles (43 ± 57.65 g and 16.44 ± 1.17 cm standard length) from the station Experimental Fish Foundation Orinoquia, Stone House of Puerto Carreño, Vichada, Colombia, were subjected to different concentrations of eugenol (30, 40 and 50 mg / L) and a control group. Statistically significant differences between treatments, for induction times and recovery time with concentrations of 20, 30 and 50 mg / L (p <0.05) were presented. Is the treatment of 20 mg / L which Eugenol como anestésico para el manejo de juveniles de Pavón (Cichla orinocensis) 31 had the highest induction time (133 ± 63.21 seconds) and the treatment of 50 mg / L had the lowest induction time (46 ± 17.51 seconds), the recovery times of the experiment increased proportionally anesthetic concentrations employed, were observed significant differences (p <0.05) between recovery times each treatment. The anesthetic concentration of eugenol recommended for juvenile pavón (C. orinocensis) obtained in this study is 35 mg / L.
