The green crab is a voracious invasive species that is wreaking havoc on many popular types of seafood species and in Maine's fishing communities. What if you could help solve this problem the next time you go to a restaurant or even when you buy a bag of treats for your dog? UMaine food scientists are looking into these and other solutions to control the green crab.

From streams and ponds to the Gulf of Maine, water defines the state of Maine in many ways. For thousands of years, counting or harvesting the plants and animals in those bodies of water has been pretty low-tech, usually involving nets of some sort. Now a new technology can do this counting using DNA and this tool will revolutionize and expand how this work is done. Beyond that it will allow the public, school groups, coastal residents and others to contribute as citizen scientists and it will enhance Maine's workforce and promote high-tech jobs as well. Michael Kinnison, a professor of evolutionary applications at UMaine speaks with us about the potential for Maine eDNA.
