California high schoolers rescue 4,000 endangered salmon
The students at Casa Grande High School in Petaluma, California, have stepped up to save endangered coho salmon. In 1993, the school built a large hatchery on campus, where students typically raise steelhead trout. Because of California’s drought, the water became too warm for 4,000 endangered coho salmon at a Lake Sonoma hatchery, and they were moved to Casa Grande, where the tanks can be kept at an optimal temperature for the fish.
