interesting question... what is the answer?
We've had a lot of conversation about this topic over the past few years... back in the early '60s at night you could shine a flashlight in shallow water by the beach and see them crawling around... they were under every rock we'd turn over... and we would set a "crayfish trap" with a dead fish, to capture them and in turn sell them to the bait shop on Moultonborough Neck for 5 cents apiece!
Over beers we've speculated on a lot of theories, but would love to know what's really behind it... there must be a scientific answer out there somewhere!
