The Sacramento blackfish is considered a delicacy when commercial anglers net it, and it can sell for up to $4 per pound on the market according to the Sacramento Bee.
But before you grab your rod and head out the door to places like Clear Lake, where they thrive (and have for centuries, they're prehistoric), you should know what you're up against. They only inhabit the deepest parts of the lake, and they live on plankton, so they won't hit a lure. But if you're bored with chasing everyday world-record largemouth bass on California's lakes, you can undertake this challenge. If you find a way to catch them, let us know. – Rick Bach
