Findings: How much Green Crabs have Grown at Fort Popham and Griffith’s Head

Green crabs have been affecting our ecosystem for as long as they've been in Maine. We are learning about them because we want to now how to get rid of them and because they're destroying our ecosystem. We caught our crabs by using a usual crab trap and caught a lot of crabs. We also put nail polish on the crabs to see if we could catch them again. I analyzed data on every year at Fort Popham and Griffiths Head and put it in a graph. The graphs show that there's been more crabs collected at Fort Popham than Griffiths Head in a short amount of time. My claim is green crabs are affecting our ecosystem and no other species could be affecting it like the green crab is.
