Every year, the Ministry of Natural Resources (MNR) stocks 140,000 whitefish into Lake Simcoe. Recently anglers have also been catching 'wild' whitefish- that reproduce naturally and are not stocked from the hatchery. For the most part the primary whitefish fishery occurs during the winter months when more people fish the lake then the other three seasons combined. However for a short window each spring an incredible opportunity has emerged that hundreds, possibly thousands of anglers are capitalizing on.
