A new book titled Do Fish Feel Pain? by the renowned scientist, Victoria Braithwaite, is a very important read for those interested in the general topic of pain in animals, especially because it has been long assumed that fish are not sentient beings and are not all that intelligent. This is a misguided view. A few years ago I reviewed the literature about sentience in fish and other animals who live beneath the surface and it's clear that a strong case can be made for protecting fish and other aquatic animals from harm. Professor Braithwaite's book contains an incredible amount of recent scientific data that support this idea.
