Abstract: A support for mounting a Conbear-type animal trap within a culvert at about the water level near a wall thereof for trapping mink and muskrat which may be swimming through the culvert. An elongate body has a clamp at one end and a support or bracket at the other end for supporting the trap near a culvert wall. The support may be a breakaway type where in one embodiment a bracket holds the trap in a desired position and allows the trap to break away upon the trapping of an animal. In another embodiment a carriage bolt is a pivot pin in the jaw eyes of the trap, the carriage bolt being secured to the end of the elongate body. The bolt may be permanently secured by mounting through a throughbore in the body, or mounted for breakaway in a V-shaped groove in the end of the support body.
