Do Fish Feel Pain?

While there has been increasing interest in recent years in the welfare of farm animals, fish are frequently thought to be different. In many people's perception, fish, with their lack of facial expressions or recognisable communication, are not seen to count when it comes to welfare. Anglingis a major sport, and fishing a big industry. Millions of fish are caught on barbed hooks, or left to die by suffocation on the decks of fishing boats.Here, biologist Victoria Braithwaite explores the question of fish pain and fish suffering, explaining what we now understand about fish behaviour, and examining the related ethical questions about how we should treat these animals. She asks why the question of pain in fish has not been raisedearlier, indicating our prejudices and assumptions; and argues that the latest and growing scientific evidence would suggest that we should widen to fish the protection currently given to birds and mammals.

Victoria Braithwaite is Chair in Fisheries and Biology, School of Forest Resources, Pennsylvania State University. She was one of the researchers who discovered "pain receptors" on fish, a finding which generated media attention around the world.
