Influence de l'anesthésie sur quelques paramètres sanguins chez le loup d'élevage Dicentrarchus labrax L. 1758

Abstract

Using anaesthetics is very common in fish farming and in scientific studies based on blood exploration. This practice is stressful for fish and it introduces a change on some blood parameters. This change depends from drug, species and environmental conditions. Two trials were effected to determine phenoxy-ethanol effects on some blood parameters in the cultured sea bass Dicentrarchus labrax. Anaesthesia is considered complete at stageIV; this stage reaches between 7 to 10 minutes by 1/5000 for concentration. The high growth of glycemia in the two trials shows that anaesthetic used is stressful for the sea bass in age 0+ and at temperature of 18 degree . But this anaesthetic isn't hypoxic for fishes.
