Abstract

Scientific research in fish consisting haematological, biochemical, bacteriological, parasitological, toxicological, immunological, somatic measurements, tagging, digital photography for morphometrics and reproductive investigations requires anaesthetization. An overdose of anaesthetic is also an effective method to euthanize fish humanely whenever necessary. The recommendations of universal ethical committee mentions that the fish should be relieved of pain (analgesia) through block of pain perception with or without the retention of other sensory abilities while collecting the blood or euthanasia.
