The effects of four anaesthetics on haematological and blood biochemical profiles in vimba bream, Vimba vimba

Abstract

The aim of this study was to compare the effect of four anaesthetics on the haematological and blood biochemical profiles of vimba bream (Vimba vimba). The haematological and blood biochemical profiles of vimba bream were evaluated 10 min and 24 h after anaesthesia with MS 222 (100 mg/l), clove oil (33 mg/l), 2-phenoxyethanol (0.4 ml/l), Propiscin (1.0 ml/l) and compared to non-anaesthetised controls. The 10 min exposure to any of the anaesthetics did not show any effects on haematological profiles. The exposure to 2-phenoxyethanol and Propiscin significantly (P < 0.01) influenced levels of glucose and ammonia, and the activity of aspartate aminotransferase compared with the control group. The level of triacylglycerols was significantly (P < 0.01) increased and the activity of lactate dehydrogenase was significantly (P < 0.01) decreased by exposure to MS 222. The use of clove oil showed no effects on the haematological and blood biochemical profiles and is recommended as a suitable anaesthetic for vimba bream. Other anaesthetics tested affected blood biochemical profiles to some extent.
