Fishers are a top predator for their size... tough and agile enough to kill porcupines. They are fast and can climb trees easily. They're also curious and confident which makes them pretty easy to trap. If it's legal by you I would not SSS but trap, skin and sell! The last two pelts I sold brought $60 for the large male and $80 for the small female...enough money for an extra roll of fencing and a trip to the feed mill.
Just curious... did you tan the pelt yourself or sell it raw? Where do you market a single pelt?
(I tanned one a number of years ago, and can't imagine selling it as it was an enormous amount of time and work...)
