The poor guy who keeps a few LMB to take home and eat isn't the one you have to worry about, the real poachers are the guys who sneek out to lakes late at night when the local dogs are sleeping snug in their beds and dreaming about twenty pound LMB. They use hand thrown gill nets and they can wipe out a hole in a couple of nights, they come and go and know ever has a clue. It's just wise to protect your turf so you can enjoy the fishing spots in your area.
