Good Morning all,

I am a beginner trapper in Northwestern Saskatchewan. I have an experienced trapper who has offered me access and assistance in getting fisher. I do not want to be a burden on him, so I am turning here in hopes of finding some blueprints/plans for a fisher box trap. Along with any things to watch out for or to include for better results.

Thanks for your time and help.

I use the same 120 size box for mink, marten and FISHER with great success:
Dimensions: For 5/8 or 3/4 inch lumber or plywood
Bottom 8” x 18”
Top 8” x 14”
Sides 6 ½” x 14”

Inside Dimensions
Width: 6 ¾ inches
Height: 6 ½ “
Notes:

1. Use restricted blackened lid cover with 2 ½” diameter hole for mink. Mink are attracted to round holes and this size hole will also restrict barn cats when trapping farm areas but allow mink and marten entrance into the box. Restricted entrance hole is
also helpful in keeping fisher out of marten sets, where required.

2. Cut spring slots to 9” depth within 5” of back of box so that trap can be set within four inches of the bait at back of box. Spring slot width is 1 inch.

3. Two 2 ½ inch finish nails up thru bottom of box at the back to impale bait on.

4. Wire mess for back of box for air/scent flow, see through effect and bird bait access.






Don't let anybody tell you a 120size BG trap is to small for a large fisher. This one got his head thru a 2 3/4 inch diameter hole and fired the trap recessed 9 inches back from the entrance

The beginning of this video shows one of the better boxes that I've seen

Appreciate the video!

saskfirst,

Another option is to build fisher/bobcat boxes out of 1x1 or 1x2 wire mesh. A lot lighter on the back.
