Anesthetic effect of eugenol in juvenile pacamã

Abstract

The objective of this work was to evaluate the effect of eugenol as an anesthetic in juvenile pacamã (Lophiosilurus alexandri). The animals were divided into two groups, named juvenile I (0.72 g) and juvenile II (7.44 g), and subjected to six treatments of eugenol (20, 40, 60, 80, 100, and 120 mg L^-1) in ten replicates. During the experiment, biometrics and timing of induction and recovery times were measured. With the increasing doses, the anesthesia duration was shortened from 69 to 27 s in juvenile I and from 93.8 to 37.3 s in juvenile II. The survival rate was 100%.
