Sturgeon Diet: What Do These Ancient Fish Eat?

Sturgeon are bottom feeders and their diet consists mainly of crustaceans, molluscs, insects, worms, and small fish. They are known to feed on shrimp, crabs, amphipods, isopods, polychaetes, oligochaetes, chironomids, and small bony fishes. Sturgeons are opportunistic feeders, meaning they will eat whatever is readily available in their environment.
