Anaesthetic Effect of Propofol on Rainbow Trout (Oncorhynchus Mykiss) in Two Different Concentrations

Abstract

Objective- The study aims to determine efficacy of propofol as an inmersión agent to induce anesthesia in rainbow trout (Oncorhynchus mykiss). Design- Experimental study. Animals- 36 healthy rainbow trout Procedure- Trouts were sorted ramdomly in two groups, 18 fish each one. Both groups were anesthesized by bath, one of them with 2,5 mg/l, the other one at 5 mg/l concentration. During the experiment, basal respiratory rate, partial and total equilibrium loss, time to anesthesia, anaesthesia respiratory rate and manipulation response were recorded. Results and Conclusion- Induction and recovery times as well as behavioural response were recorded, being significantly affected by propofol concentration (P Clinical relevance- The results of the present work provide data to be used in surgical procedures and containment maneuvers in the different practices performed in fish farming.
