It is our responsibility to know the regulations...if there is confusion then they should ask in forums such as this or call the MNR for clarification...
I doubt they (MNR) will ever open pickerel (walleye) for icefishing in the Kawarthas (Except Scugog) The main reason for the new size and possession limits is to try to get them to rebound...
Panfish, Pike and coarse fish only will have a year round open season but again, read up on possession limits for perch, crappie and sunfishes including bluegills...
