More commonly known as Muskie, this aggressive sport fish closely resembles a much larger northern pike or American pickerel in both appearance and behavior. The Muskie, like other pikes is an ambush predator; however this fish can reach lengths between two and five feet and weights of over 66 pounds. Artificially introduced into the St. John River watershed, anglers now seek the large fish as trophies or for sport. Muskies are known for their strength and for their tendency to leap from the water in stunning acrobatic displays. One of the fastest growing events in the region is the International Muskie Derby held each August in the town of Fort Kent.
