Labor Day - Monday, Sept. 3 – marks the second of two free fishing days in the Commonwealth. Fish For Free Days allow anyone – residents and non-residents – to legally fish in Pennsylvania. From 12:01 a.m. to 11:59 p.m. on both days, no fishing license is needed to fish in Pennsylvania's waterways. All other fishing regulations apply. The first 2012 Fish for Free Day was Memorial Day – Monday, May 28.
