The New Food Economy
Jeffres opens the top of the cage and dips in a small net. When he pulls it out, a pair of plump fish, each the size of a pinky finger, wriggle inside. These are young Chinook salmon—a species imperiled in California. He holds up his catch for Katz to admire.
The two men are fish ecologists—Jeffres at the University of California, Davis, and Katz at the conservation-based non-profit California Trout—and they are testing a wild idea. To help save the Chinook, they are using rice fields as winter nurseries for young salmon migrating from their natal streams to the ocean.
