🐠 What Is FINS?
FINS stands for Friant Interactive Nature Site, and it centers around one of California’s important fish hatcheries, located along the beautiful San Joaquin River. The main highlight of this site is the San Joaquin Hatchery, where thousands of young salmon are raised each year. These baby salmon, called fry, start their lives as tiny eggs in the hatchery. Inside the Hatchery Building, visitors can view long, clear tanks full of growing salmon and learn all about how hatcheries support the environment.
Trained hatchery staff work hard to monitor water quality, feeding schedules, and fish health daily. Once the salmon are large and strong enough, they’re carefully released into various rivers throughout California. This process helps maintain healthy fish populations and supports wildlife conservation efforts across the state.
Visitors can walk through the hatchery building and see the process in action. It’s both educational and fascinating, especially for children or anyone interested in how ecosystems work. You’ll leave with a better understanding of how humans can help protect and restore nature — all while seeing hundreds of wriggling baby fish up close!
