Here is a fisher that was caught as an incidental in a snare last year.Here is a pic of it in the snare,dried on the board,and back after tanning.
Although it looked OK after drying I knew it would grade damaged,as any defects are magnified after dressing and the graders know this.
I have a use for this fisher,as there is a lot of useable fur on the pelt beyond the dmg at the neck.





You can see the dmg at the neck on the female skin on the left.The skin on the right is a male fisher.

As to snare damage.

I once caught a coon that was body caught In a snare and the snare was still on the coon.. I don't how long It had been on the coon. But when I went to skin It the hide tore right at the snare mark.

There was no damage on the leather,just the fur from him fighting the snare.Hate to catch fishers as incidentals in snares.Had a box close by but I guess he came in from the wrong direction and didn't make it to the box.If I remember correctly he was twisted up in two snares around his neck,but they sure fight unlike a fox or cat.Tough Animal.
