How do you target male fisher? In the past, I have used 160's in a bucket on the ground with success. Unfortuanlly, I have only caught females. Is there a way to target just the big males other than footholds or cages where females can be released?

I seriously doubt it as a fisher is an opportunistic predator/scavenger that will eat virtually anything; berries, birds and eggs, fish and of coarse MEAT; thus are easy to trap.

If you what only Male fisher then you should use live traps and just release the females. When they do marten and fisher studies they use live traps so you should be able to catch them that way.

Having only been tracking fisher in the snow for 5 years and having a limited season here in New York 5 days, these are some of my observation, these can also be coroberated by early writing of Dailey Arnold Locke and Woods. Big male fisher are like bobcats and old buck mink, they know where the females are at and keep tabs on them. I have noticed that these large fishers will not go around ponds and streams but actually swim across, they do not even shake off, they come out wet and keep moving they will go straight thru a swamp. You will find they use the same crossing every year. They will lay up in big woods, high on a large limb or hole, in the day where they have great visibility and will watch their domain and react to what ever enters it, these location are where old coon dens use to be, they are now long gone. So look for old growth coon habitat that does not have any coons and you might get onto a big fishers core area. They also have toilets near these sites, any one that has seen a mink den or a domesticated ferret will show you that they tend to go at the same spot. I have found multiple toilets on snags, with leaning timbers, blow downs. do not overlook large trees that cross streams even small streams, check for droppings. I know most will disagree but try targeting male only, you appear to be able to find the litters. it does require a little walking. Good luck. One other item, a heavier trap like an MB will wear them out quicker making them easier to release when caught out of season in coyote sets.
