Do Fish Feel Pain?

Biologist Victoria Braithwaite examines the question of fish pain and fish welfare, explaining how new research shows fish to be more intelligent and responsive than we believed, and exploring how this relates to the ethical questions about their treatment by fish-keepers, in the sport of angling, and in the fish-farming industry.

Résumé
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. Angling is 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 raised earlier, 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 andmammals.
