Fish welfare is currently a controversial subject with many scientific studies now demonstrating the possibility for fish to experience negative events such as pain, fear and stress. This has important implications in the treatment of fish during commercial and experimental procedures in terms of ethics and welfare. In this review, the evidence for pain perception in fish is considered and the repercussions for the use of fish as a research model as well as in aquaculture and largescale fisheries. These issues are discussed briefly from a welfare and ethical perspective.
