I approached this book with from a rather skeptical perspective, but found myself won over by the strength of the author's argument. It would be easy to slip into simple advocacy, but Braithwaite artfully avoids this trap - instead, she allows the data to speak for themselves, and takes the reader through the series of well designed experimental steps that are necessary to defend her contention that fish do indeed feel pain. It is science at its best - clear, methodical, and rational. I'd recommend it highly to students, not just as a study in fish biology, but also as an example of how to present an emotive argument without letting emotion cloud the issue.
