Modeling the impacts of the European green crab on commercial shellfisheries.

Coastal resource managers are often tasked with managing coastal ecosystems that are stressed by overexploitation, climate change, contaminants, and habitat loss, as well as biological invasions. Therefore, managers increasingly need better economic data to help them prioritize their management strategies and distribute their increasingly limited resources to those strategies. Despite frequent pronouncements about the substantial ecological and economic impacts of invasive species, there have been few if any rigorous analyses of the economic impacts of invasive species in coastal systems.

The U.S. Environmental Protection Agency has proposed permitting ballast water discharges--a benefit of which would be to reduce the economic damages associated with the introduction and spread of aquatic invasive species.
