There is a perception that fish have simple brains and are incapable of feelings. New research by Dr. Victoria Braithwaite, Associate Director of the Penn State Institute of the Neurosciences and a Professor of Fisheries and Biology, has resulted in evidence that suggests fish are more intelligent than previously thought and their behaviour more complex.

In her new book, Do Fish Feel Pain?, she discusses what she has discovered about the capacity of fish to experience pain and suffering. She contends we should balance their welfare with the many ways they provide us with benefits. Hear her discuss her work and the evidence behind it with Quirks & Quarks host Bob McDonald.
