Haematological and biochemical response of burbot (Lota lota L.) exposed to four different anaesthetics

Abstract

The aim of this study was to compare the effect of four anaesthetics on haematological and biochemical blood profiles in burbot Lota lota L. Blood profiles of burbot were evaluated 10 min and 24 h after anaesthesia with tricaine methanesulfonate (MS 222) (100 mg/l), clove oil (33 mg/l), 2-phenoxyethanol (0.3 ml/l), Propiscin (1 ml/l) and compared to non-anaesthetized control. The tested anaesthetics had no effect on haematological profile of burbot. The exposure to clove oil, 2-phenoxyethanol, and Propiscin significantly (P < 0.01) influenced the level of ammonia and glucose. The level of lactate was significantly (P < 0.01) increased following anaesthesia with 2-phenoxyethanol and Propiscin. The levels of total protein, aspartate aminotransferase, and calcium were higher (P < 0.01) with clove oil, 2-phenoxyethanol, and Propiscin compared to control. The use of MS 222 showed the lowest effect on haematological and biochemical blood profile and is recommended as a suitable anaesthetic for burbot.
