The graph above shows the rate of sea lamprey wounds on the native fish species, Lake Trout and Atlantic Salmon, in terms of woulds per 100 fish. Overall, it seems as though the peak of sea lamprey attacks occurred during 2003 till 2006, with lowest rates in 2010 for salmon and 2011 for lake trout.
