Description
The invasive European green crab, Carcinus maenas, has been present in Maines Casco Bay since the 1950s, but in the past decade has increased in abundance and now threatens small native bivalves, including the economically important soft shell clam. This project is an effort to model the interactions of the green crab and soft shell clam using the dynamic system modeling software STELLA. The model provides a framework to evaluate policy decisions based on the best known information, which can be easily updated as it becomes available. The model shows a price per pound of crab above which sufficient crabs will be harvested to eventually reduce their population to below a sustainable level and allow recovery of the soft shell clam fishery.
