While the campaign to consume more invasive green crab has ramped up over the last few years, the act of catching, hunting or foraging invasive species for the purpose of eating them is nothing new.

During part of his PhD research in organismic and evolutionary biology, Roman chose to study the genetics of the European green crab to try to better understand how the species got to North America — and how its population expanded so rapidly.

It's also unrealistic to expect consumers to eat every single last green crab, lionfish or periwinkle.

What patrons may not realize, however, is that by indulging in green crab for dinner, they're also working to combat the growth of an invasive species.

With few natural predators, invasive green crab populations have dug in, overtaking the eelgrass beds that native birds and fish depend upon to survive.
