This study investigated the feasibility of using clove oil, 2‐phenoxyethanol, or Propiscin as an alternative to tricaine methane sulphonate (MS 222) as a fish anaesthetic, particularly in regard to reducing fish stress. The biochemical blood profiles of perch Perca fluviatilis L. anaesthetized with either MS 222 (100 mg L −1 ), clove oil (33 mg L −1 ), 2‐phenoxyethanol (0.40 mL L −1 ) or Propiscin (1.0 mL L −1 ), and a non‐anaesthetized control group were compared. Biochemical profiles were determined from blood samples collected before treatment in controls. For each anaesthetic tested, fish were divided into two groups, one sampled immediately after 10‐min anaesthesia and a second, sampled 24 h after 10‐min anaesthesia. The values determined in the present study suggested that internal organs and tissues of perch were slightly altered by MS 222, clove oil and 2‐phenoxyethanol anaesthesia, but not by Propiscin anaesthesia.
