Rehabilitated lake trout
areas of the Great Lakes
• Many locations of Great Lakes excessive lake trout mortality by sea lamprey & exploitation has hindered or prevented rehabilitation.
•All of success highlights the need for significant controls on exploitation to achieve rehabilitation
• Low bag limits, maximum size limit, very short harvest seasons and refuge area were most effective management techniques used in Parry Sound to control angling mortality.
•May need to consider these in other areas
•OMNR is closely reviewing the commercial fish harvesting data to develop methods to reduce incidental harvest
