A fisher is an opportunistic predator/scavenger that will eat virtually anything; berries, birds and eggs, fish and of coarse MEAT. I prefer beaver for bait as it gives off a good odour when even frozen but moose, deer and fish are also good baits. Many lures will attract them, beaver castor, fish oil and marten lures. One with skunk in it is great for very cold weather conditions.
Fisher can be caught in many set types but I prefer a box set on a leaning tree or running pole.
When using a horizontal or inclined trap box be it with standard wire or pan trigger, if it is set too far away from the bait the animal sometimes moves through the wire trigger or jumps over the pan and fires the trap with its body or hind feet, resulting in a hip catch. With a 120-trap set within 4-6 inches of the bait, you will get a neck or neck and thorax quick kill zone strike virtually every time. This occurs because the animal is stable at the bait, not moving through, and centered towards the trap when it is triggered.
While working the bait in a 14” plus long box with long spring slots the animal will be correctly oriented to the trap, stable, not moving through the trap and most likely mink and marten will be standing with front feet on a pan trigger or moving its head within the trigger wires while working the bait. The fisher will usually trigger either a pan or wire trigger 120 trap with its head movements while working the bait.
