Both beautiful and controversial, the rainbow trout has become the most commonly stocked freshwater fish in the United States. Author Anders Halverson provides an exhaustively researched and grippingly rendered account of this paradoxical fish and how it's been managed for more than 130 years by government officials. Dubbed "an entirely synthetic fish" by fisheries managers, the rainbow trout has been introduced into every state and province in the United States, and to every continent except Antarctica, often with devastating side effects on native fauna. Ultimately, it's a story and history of about our relationship with the natural world and the changes, both positive and negative, that we have helped create.
