Anders Halverson

An Entirely Synthetic Fish Review

The last century has seen the rapid spread of the rainbow trout across the USA, and Anders Halverson's award-winning book "An Entirely Synthetic Fish" does an excellent job of chronicling the rainbow trout's manmade diaspora - along with the negative effects on native fish populations.

Halverson is a thorough researcher and a fine storyteller, and his engaging book never lags or lapses into biologist "geekspeak."

Instead, it's an engrossing read - one that's hard to put down, and just as hard to forget.

Halverson dives into the history of the rainbow trout starting with the expedition up the still-wild (and dangerous) McCloud River to establish a hatchery.

With sportsmen cheering every step of the way, Halverson highlights the rainbow's rapid spread across the USA (and the planet), and the displacement (and wholesale extinction) of the native species who get in the way.

Fortunately, he manages to do this without casting the fisheries managers behind the rainbow diaspora as "bad guys."

It was a "conqeur the wilderness" era, and it wasn't until the watershed event on the Green River - where biologists used tons of Rotenone to poison out every last native species so millions of rainbows could be stocked - that fisheries people finally blinked.

Halverson's account of the Green River project was gripping, and in fact, read a lot like a novel (I half-expected Bond to show up).

Later, Halverson examined Montana's "no stocking" legacy, the impact of whirling disease on several key fisheries, and the ill-fated decision of Colorado's hatchery program to knowingly stock whirling-infected rainbow trout in almost all the state's waters.

Halverson's examination of the Sierra lakes hit closer to home, where rainbow trout introductions into formerly fishless alpine lakes played havoc with amphibian populations.

As someone who lives and fishes in the mountains of California, I've heard a great deal of grumbling from "sportsmen" about the high country fish removal policies, especially since "our" trout are being removed to protect frogs, which most people don't fish for.

Clearly, the "sportsmen first, natives second" attitudes of the past century still loom large in many of today's outdoorsmen (witness the cutthroat recovery and wolf reintroduction issues of the Northern Rockies), and while it's tempting to dismiss Halverson's book as documenting a bygone era, that's more self-delusion than reality.

Overall, An Entirely Synthetic Fish is an engrossing book that sometimes reads like a novel (though its 30 page bibliography will dissuade you from that thought).

It deservedly won a National Outdoor Book Award, and is well worth any fly fishermen's time.

A well written and knowledgeable review of the history and current status of the introduction of rainbow trout into the fisheries of the world. The author is a biologist with a storyteller's gift for bringing to life what could have been a dull historical review. Impressively researched, the book tells the story of how rainbow trout, native only to the Pacific Coast of North America, come to be found in all the waters of the world. Along the way we learn how the fish have affected us, our science, our recreation and our viewpoint regarding nature. The author is an angler and a scientist. As such he presents an even handed viewpoint on a subject ripe with conflicting interests and illuminates many decisions by governmental agencies that would be otherwise incomprehensible. For example, he explains how the California Department of fish & game stocked high Sierra lakes with trout for years and then reversed course and began to eradicate the non-natives. As one who has witnessed these eradication efforts with disapproval and misunderstanding I am pleased to learn that there appears to be a rational basis for the effort and that it is not directed at wiping out trout from all Sierra lakes. Further, my own preference for catch and release fishing of wild native species, or non hatchery fish at least, is shared by the author and his preference is supported and explained by this gem of a book.
