Great Lakes: Lake Trout Harvest Limits

Lake trout harvest limits

Lake trout is the top native predatory fish species in the Great Lakes, supporting important fisheries throughout the region. Lake trout are managed to promote long term sustainability of these fisheries as well as to support the overall stability of the Great Lakes ecology.

Establishing safe harvest levels for lake trout is crucial for meeting long-term management and rehabilitation goals. Information collected from monitoring sport and commercial fisheries, along with cooperative surveys conducted by state, tribal and federal resource agencies in the 1836 Treaty waters of lakes Huron, Michigan and Superior, is used to assess the status of lake trout populations, or stocks, in each management area.

These assessments help determine the appropriate overall harvest limit for each management area. Harvest limits vary from unit to unit based on the status of the population and how the safe harvest limit is divided between the state and tribes.
