Edinboro Lake

Got out for the opening of bass.  Used a repala, casting from shore had a few nudges from small fish; saw some big ones hitting the bait fish.  No luck.  Saw about a half dozen boats with fishermen on the lake.  Most were Mennonites  fishing in john boats with two, three or four in a boat. 
 
My question is.  How many Amish and Mennonites fish without a license (I didn't see any liscenses) and how soon can a lake be fished out under no restrictions?  I am not a catch and release guy.  I think fishing for food is a fundamental right, however, we all fish under certain size and number limitations. If not, the limitations as established by the fish commission, are not adequte and we all suffer for both food and sport.
 
Just interested  in the facts.
