Caution! The alligator snapping turtle (Macrochelys temminckii) occurs in southern Missouri in small numbers. It is a species of conservation concern and may not be shot or trapped under this rule. Identify the common snapping turtle correctly before taking control action! Detailed illustrations to the right and on page 15 of the Summary of Missouri Fishing Regulations PDF, listed under Related Information below, show you the differences between the two species.
The common snapping turtle (Chelydra serpentina serpentina) is present throughout Missouri and can occur wherever there is permanent water. Largely beneficial, it seldom causes damage but occasionally takes small ducks and goslings. Generally, reducing snapping turtle numbers does not affect fish abundance or fishing success.
The Wildlife Code of Missouri classifies the common snapping turtle as a game animal that may be taken during the prescribed season. See current regulations for details. The Code also specifies that damage-causing common snapping turtles may be shot or trapped out-of-season without a permit; refer to 3 CSR 10-4.130 Owner May Protect Property; Public Safety of the Code for details and restrictions.
Exclusion. Not a practical option.
Fumigants/repellents. None are registered.
Hook and line. Bank lines are made by tying 4 or 5 feet of fishing line to a stout flexible pole or trimmed tree limb 6 to 8 feet long. Place about 12 inches of No. 16 steel wire between the line and hook, preferably a stout hook with about 1 inch between the barb and shaft. Push the pole far enough into the bank to make it secure at an angle that will hold the bait a few inches above the bottom. If possible, set poles in relatively shallow areas near aquatic plant beds or under overhanging banks, stumps, or other cover. Bait with cut fish or other fresh meat. Non-target turtle species must be released unharmed.
Trapping. Hoop-net traps are the most effective way to remove damage-causing common snapping turtles. These barrel-shaped traps are typically 4 to 6 feet long with three, four, or five hoops of wood or 6-guage steel wire. Search the Internet to purchase ready-made traps or make your own using 3-inch square mesh of No. 24 nylon seine twine. Detailed information for trap construction is available from the Internet Center for Wildlife Damage Management website listed below. Trapping is most effective in the spring, summer, and early fall.
Shooting. Although this method is unreliable, common snapping turtles can be shot, where allowed, if the opportunity arises. Check with local authorities regarding the use of firearms. Correct identification is crucial because other turtle species cause no damage. Exercise caution because ricocheting bullets are unpredictable and dangerous. Please note that shooting is not a legal method for taking common snapping turtles during the prescribed season.
