Connecticut Public Radio News Director Jeff Cohen and I both once lived in New Orleans, so we know that if it looks like a cute little mini lobster, it’s actually -- probably -- what they call down there a “crawdaddy.” Up here in the Northeast, we call it a “crayfish.” There have been reports of an increase in sightings of crayfish on land and in bodies of water around Connecticut this year, and the state Department of Energy and Environmental Protection is none too thrilled. Mike Beauchene, a supervising fisheries biologist at DEEP, told All Things Considered these new crayfish are from Louisiana, and they’re bullies. Mike also tells us about some other invasive species muscling in on our native wildlife and what you can do to help.
