Characteristics of trophy-sized muskellunge

An effort was made to compile a listing of trophy-sized muskellunge which have been angled from Ontario waters. A trophy-sized muskellunge in this study was defined as a fish exceeding 114 cm (45 inches) in length or 10.0 kg (22 pounds) in weight. Information was obtained for a total of 9,708 muskellunge which were angled in Ontario between 1917 and 2010. The majority of records originated from volunteer angler diaries maintained by members of Muskies Inc. and Muskies Canada Inc. Most trophy-sized muskellunge were angled early in the season and numbers decreased as the season progressed. The geographic distribution of trophy-sized muskellunge was spread well over their Ontario range. There was a significant positive trend in the maximum size of muskellunge reported annually. There was also a significant increase in the maximum size of muskellunge reported after the changes to minimum size limit regulations in 2001. An increase in the catch-and-release angling ethic in conjunction with the implementation of new minimum size limit regulations is believed to be responsible for the increased number of trophy-sized muskellunge being angled in Ontario. Based on the number of Ontario waters producing trophy-sized muskellunge and the increasing number of trophy-sized fish being reported annually, Ontario’s muskellunge management strategy appears to be achieving the objective of  providing a diversity of trophy angling opportunities.
