How Rainbow Trout Beguiled America and Overran the World
by Anders Halverson
It\’s about rainbow trout. How they became so popular among fishermen, how hatcheries evolved to populate the streams and rivers, driven by the revenue brought in by sportsmen who then demanded certain provisions. This is back in the sixties and earlier. Entire watersheds were poisoned to remove \”undesirable\” fish and restock with rainbow trout. That part was awful to read. A lot of this is about management politics and departmental bickering over policies- sadly no real studies into the situation of fish in the rivers was done until it was too late. By then genetic testing and numbers revealed that most fish had rainbow trout ancestry to some degree- so lots of native fishes aren\’t in their original form anymore but the offspring of hybrids. In a complete about-face, fish and game departments started removing rainbow trout from the rivers they had once worked so hard to stock- when they realized that native fish and some ecosystems were threatened to disappear (fish and frogs don\’t mix- some frogs in lakes that had never seen fish until they were artificially stocked almost went extinct). The parts about genetics, fish behavior, wild vs hatchery-raised and even disease outbreaks (whirling disease) were interesting. The parts about how exactly why rainbow trout came to be so esteemed over other \”trash\” fish, and how certain groups of sportsmen tried to control access to fishing areas- seeing themselves as aristocrats in a way- not so much.
I\’m not sure how to rate this book. It\’s one of those I didn\’t really read all the way through- skimming large sections that were just dull and reading with more attention the parts that caught my interest. I probably skipped a third of the book. As I knew going into it, the book is more about the history of organizations and people who dealt with the fish than it is about fishes.
