The C120 Magnum trap, equipped with a 66 × 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 <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 >79% of all captured mink unconscious in ≤3 min (P < 0.05). This is the first mink kill trap to meet the requisites of the Canadian General Standards Board regarding killing traps.
