Missouri's new regulation is another step to prevent new invasions.
On May 31, the Conservation Commission approved the commercial sales of only northern crayfish (Orconectes virilis), also known as “virile” crayfish, from in-state sources for live bait, effective March 1, 2014.
The regulation limits the sale, purchase and importation of other species 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 other species 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.
Other states already ban the sale, use or importation of live crayfish as bait to some degree. Those states include Arizona, Idaho, Maryland, Minnesota, Nevada, Oregon, Utah, Virginia, Washington, Wisconsin and Wyoming. Arkansas and Pennsylvania are considering a ban.
