It’s easy to see how biologists studying the fate of California’s native fish might fall into despair. That’s how Jacob Katz felt when he and his colleagues in 2011 that more than three-quarters of the state’s native freshwater fish, including its iconic Chinook salmon, were in sharp decline. But Katz, a fly-fishing ecologist who directs Central Valley operations for the conservation nonprofit California Trout, isn’t the despairing type. His eyes lit up as he recalled the moment he realized the same forces leading California’s fish to the brink of extinction could be harnessed to reel...…It’s easy to see how biologists studying the fate of California’s native fish might fall into despair.
