Living in Eastern Pa, skin mounts are far from the problem - a lot of the people fishing here keep everything to eat. And by everything, I mean everything. There are a few guys I run into that only live bait fish and last June (when it is illegal to keep any bass in Pa) they had a bucket with 12 bass, a bunch of perch, all sizes of sunfish, a dozen or more trout, a few bullheads and numerous small pickerel. They don't care what they catch, they keep them all. I have found these same guys with buckets of 2-3" sunfish and bluegill they keep to eat. Usually they have 10-15 poles cast out, all with sabiki rigs using various live baits.
This is my concern, not keeping a few fish. Also, large fish sometimes die when you catch them...may as well get it mounted if it's a great catch.
