“This smart little book has all the trappings of a historical account, with endnotes, an extensive bibliography, and a comprehensive index, but it can also be read as a whodunit. The crime scene is the Pacific Ocean, and the motive was access to the fish resources that both Japan and the US were exploiting and/or eyeing, especially salmon in Alaska and tuna in the Pacific, the latter also requiring small bait fishes from coastal waters in Central America. The victim was good faith—the use of argument based on scientific evidence to articulate legitimate positions. The villain is US foreign policy, specifically its fisheries branch . . . [and] the weapon used for the deed, and the main theme of this book, was the concept of ‘maximum sustainable yield’ (MSY), used by Latin American politicians who objected to the expansion of US tuna fisheries into what later became their exclusive economic zones (EEZs), long before MSY became quantifiable.”
