DNR can not be every where - they need our help to stop poachers. Give them as much info as you can. These officers really care about protecting the resource from poachers.
If you see some thing odd - give DNR a call. Heck , there is even reward money some times.
I can not imagine a rec. taking time to bait two or three 1,500 foot trot lines to get crabs for dinner. That much effort - sounds like he is selling them. The bait bill alone for that much line could buy a bushel of #1's.
What could be more mundane than dying of old age or of natural causes when there is death by misadventure to be pursued ? Skip
