Inside the world’s first caviar farm that uses fish waste to grow food

On a farm just outside of Sacramento, hundreds of prehistoric-looking fish swim around in 50-foot diameter tanks. These are white sturgeon, the largest freshwater fish in North America. They’ve been around since dinosaurs, can grow more than 7 feet long and lay hundreds of thousands of eggs at a time.
