I'll send you a message when I'm ready to start haha. In Pa, you can collect any native species as long as you have a fishing license (still have to follow creel and size limits) and they aren't endangered. I think there are special regulations on Pike, but I'm not going for them. There are also regulations on the nets you can use (size and type limits). I hear NY is much more strict on obtaining fish.
I did my collecting in the NJ Pine Barrons.
I'm surprised NJ has live fish I kid, I kid! I was fishing in the Juniata a few months ago and walked through a tiny mountain runoff that went into the river... Sitting right in front of that run off, half of it's body out of the water, was a 6" bowfin. I almost touched the darn thing and could have probably caught it if I wanted... They probably get too big for what I want to build though...
