|It is legal* to fish for trout in Class A
trout streams year-round, with no kill beginning the day after Labor Day through the opening day of trout season the following year. The same holds true for wilderness trout streams.
Of course, all other fishing regulations still apply.
Note that during the period after Labor Day through the following opening day of trout season, anglers must immediately release any trout they catch unharmed to the waters from which taken. Anglers also should check for special regulations applicable to particular waters.
The traditional trout season and creel limits are in place for "Stocked Trout Waters," which basically means the water is stocked by the Commission or one of its Cooperative Nursery partners. To provide additional angling opportunities, there are a handful of stocked trout waters that are open to year-round fishing.
Another option for year-round fishing is a special regulation area. There are dozens located throughout Pennsylvania that are open to year-round fishing. Note many of these are catch and release only, have tackle restrictions, etc. Consult the PA summary book or signs at the areas for specific regulations.
A number of special regulation areas are under Delayed Harvest Artificial Lures Only regulations. These areas are open to year-round fishing with no kill, except from one hour before sunrise on June 15 to one hour after sunset on Labor Day, when the daily creel limit is 3 trout (combined species) with a minimum size of 9 inches.
All these categories and regulations may seem a bit confusing, but it's really pretty simple:
