Velíšek J., Z. Svobodová, V. Piačková: Effects of 2-Phenoxyethanol Anaesthesia on Haematological Profi le on Common Carp (Cyprinus carpio) and Rainbow Trout (Oncorhynchus mykiss). Acta Vet. Brno 2007, 76: 487-492. The aim of this study was to assess changes in haematological profi le of common carp (Cyprinus carpio) and rainbow trout (Oncorhynchus mykiss) after the exposure to anaesthetic 2-phenoxyethanol. The haematological profi le was assessed before, immediately after 10 min of anaesthesia

... nd 24 h after the anaesthesia with recommended concentration of 0.30 ml·l -1 2-phenoxyethanol. The 10-min exposure to 2-phenoxyethanol of common carp caused the signifi cant increase (p < 0.01) in the haematocrit value and relative and actual count of monocytes immediately after the anaesthesia. These values returned back to normal within 24 hours. In rainbow trout, 2-phenoxyethanol anaesthesia had no effect on the haematological profi le. Results of the examinations suggest that the use of 2-phenoxyethanol at the concentration of 0.30 ml·l -1 does not cause irreversible damage of the blood in common carp and rainbow trout.
