I have been chosen to give a talk to the volunteer friends of a local wildlife refuge on the subject of Crayfish. They're fairly common here in tidewater virginia, but so far, I havent found any good field taxonomy keys for keying out crawdads that I catch- and I'm having a good bit of trouble catching them.
There are plenty around my house, but the water is too shallow for trapping them. Various web resources say to try digging them out, but I haven't met with any success doing so- that there are a lot more common species in larger bodies of water that you can trap, but for rarer things, you'll likely have to dig them out of an ephemeral ditch or something. I need advice on: A good general field guide or textbook, and general advice / experience on how to lay a hand on the critters. It's been dry around here lately too, and that hasn't helped. Thanks to any and all, Inigo
