Eriocheir sinesis Chinese Mitten Crab By : Mariana Acevedo

You should know… Kingdom:Animalia Phylum: Anthropada Class: Malacostraca Von SeiboldLatrieille

Today the crab can be found in… West Coast Waters Chesapeake Bay Great Lakes Yellow Sea (China) Started out: China First distributed to: West Coast U.S.A (California, Oregon, Washington) Modes of “transportation”: -Ballast water -Intentional placement -Crabs clinging to boat hulls

EFFECTS… On Humans -Carries parasites -Costly extermination attempts -Number of caught fish goes down = less food for the population On Nature -Reproduce quickly therefore, more food is needed -Tiny fish are the prey -Animals who eat the smaller fish are running out of food

FOOD WEB Aquatic plants Small Fish River Otter Chinese Mitten Crab

Key To Success Reproduction is simple to the Chinese Mitten Crab, so numbers are able to be maintained. Juvenile Chinese Mitten Crab Any attempt to exterminate the crabs have been unsuccessful.

FUTURE Failed AttemptsTrade-offs Controlled barriers Hurts other fish Crab catching Prevents certain fish from migrating Electrical screens Expenses, expenses, expenses Other Options “Herding” Send in predators Make reserves
