Invasive Mitten Crab Found in Pacific Northwest for First Time

An invasive Chinese mitten crab has been found in the Lower Columbia River, Oregon, marking the first confirmed sighting of the species in the Pacific Northwest. The crab, notable for its distinctive mitten-like claws and ability to climb heights up to 13 feet, was caught by a commercial fisherman.

Oregon wildlife officials have identified the crab and are now assessing the potential risks it poses to the local environment. Chinese mitten crabs are known to be highly invasive, capable of disrupting ecosystems by competing with native species for food and habitat. Their burrowing habits can also damage riverbanks and agricultural lands.

The discovery has prompted increased monitoring efforts in the Columbia River and surrounding waterways. Scientists are working to determine the extent of the crab's population and develop strategies to control its spread. Eradication efforts, if deemed feasible, could be costly and time-consuming. The public is encouraged to report any sightings of the crab to local wildlife authorities. Early detection is crucial in managing invasive species and minimizing their impact on native ecosystems.
