MDC has a new regulation to help stop crayfish invasions in Missouri waters by eliminating key sources of live crayfish (also called crawdads) that can and do become invasive. The regulation limits the sale, purchase and importation of live crayfish in the state to human consumption, scientific research, or as food for confined animals kept by approved entities such as research institutions, agencies or publicly owned zoos. The regulation prohibits the importation, sale or purchase of live crayfish in the state for all other uses, such as fishing bait, pond stocking or as pets or pet food. The new regulation does not apply to other types of bait or to dead or preserved crayfish. Anglers may still catch live crayfish for use as bait. Please share your comments below.
