Evaluación de la actividad depresora de etomidato en dos concentraciones en trucha arcoíris (Onchorhyncus mykiss)

The aim of this study was to evaluate the depressing activity of etomidate at concentrations of 1 and 2 ppm/L in rainbow trout from an intensive breeding system in Córdoba, Argentina. The use of the anaesthetic, regardless of the dose, produced a reduction in respiratory frequency between 61 and 66%...

Description
Summary:The aim of this study was to evaluate the depressing activity of etomidate at concentrations of 1 and 2 ppm/L in rainbow trout from an intensive breeding system in Córdoba, Argentina. The use of the anaesthetic, regardless of the dose, produced a reduction in respiratory frequency between 61 and 66% in anaesthesia compared to the basal respiratory frequency (p<0.05). The times of partial and total loss of equilibrium and in anaesthesia were statistically lower (p<0.05) at the dose of 2 ppm/L, while the recovery time did not present significant differences (p>0.05) between groups. The concentrations used induced a dose-dependent state of anaesthesia that allows the manipulation of the fish without adverse effects that compromise the life of the fish.
