The "new" didn't mean new- I know they were here before most game species- it is just people didn't see them often and except for where you are fishing they are rare- here's a link about them from Fish and Boat

Also all fish are covered by regulations in PA- not always as individual species. The inland regulations state that either a fish is protected (like paddlefish) or it is covered as a game fish- if no creel limit is set for the species then it falls under the same regs as sunfish or baitfish - 50 combined species open year round.

Since they are more common where you are fishing, Fish and Boat may be interested in the information. It is also illegal to kill a fish and not make an effort to properly dispose of it- regulations

"To kill any fish and fail to make a reasonable effort to lawfully dispose of it."
