Nose is too pointy and snout is too long , and tail is too thin to be a fisher. I've seen hundreds of them on video on me trail cams.

Looks more like an otter or a mink to me. I slightly favor a mink over an otter . Otter like moving water over a swamp.
Mink are more prone to take up residence around swamps

A fisher. I've seen them many times along the edge of a swamp.

where are you located?
