The C120 Magnum with pan trigger: a humane trap for mink (Mustela vison).

The C120 Magnum trap, equipped with a 66 x 69 mm pan trigger, which favored double strikes in the neck and thorax regions, successfully killed nine of nine wild mink (Mustela vison) in simulated natural conditions. Average times to loss of consciousness and heartbeat were estimated at less than 72 (+/- 24) sec and 158 (+/- 48) sec, respectively, after firing of the trap. This study confirmed that the C120 Magnum trap can be expected to render greater than 79% of all captured mink unconscious in less than or equal to 3 min (P less than 0.05). This is the first mink kill trap to meet the requisites of the Canadian General Standards Board regarding killing traps.
