Influence of 1-phenoxy-2-propanol on blood profile of common carp

Abstract

1-phenoxy-2-propanol is a common and effective anaesthetic for aquatic organisms such as bivalves and pulmonates. However, there are no data regarding its influence on fish organisms. In the present study the anaesthetic efficacy of 1-phenoxy-2-propanol and its influence on biochemical and haematological blood indices of juvenile common carp were studied. For blood profile test, fish were divided into four groups (n = 10). The haematological and blood biochemical profiles of common carp were evaluated 10 min and 24 h after anaesthesia with 1-phenoxy-2-propanol (400 mg·dm-3) and compared to non-anaesthetized control groups. Significant changes (P < 0.05) in red blood cell indices and in white blood cell count were found as well. Increased concentrations of glucose, ammonia and inorganic phosphates indicate that stress reaction occurred. No changes in total protein, globulin, triacylglycerols, alkaline phosphatase, aspartate aminotransferase and calcium were found. Although exposure to 1-phenoxy-2-propanol caused a moderate, temporary stress response in examined fish, we can state that 1-phenoxy-2-propanol can be used as an effective anaesthetic for common carp.
