Why is there a lake trout natural reproduction problem?
Natural recruitment failure affects a number of coldwater fish species in Lake Simcoe. Lake trout, lake whitefish and lake herring populations have all suffered drastically such that lake herring are now virtually gone from the lake while lake trout and lake whitefish populations are being maintained only through fish stocking. The problem stems from excessive nutrient loading into Lake Simcoe, which in turn, is adversely affecting the habitat of the coldwater fish species. Efforts to combat this problem are coordinated through the Lake Simcoe Environmental Management Strategy (LSEMS). LSEMS is a multi-agency partnership whose goal is to protect, maintain and improve the health of the Lake Simcoe ecosystem by reducing nutrient loading and restoring a naturally reproducing coldwater fishery. What next? The LSFAU will continue long-term monitoring and assessment of Lake Simcoe fish populations and the factors affecting them (water quality, habitat, fishing, species introductions). In add
