I went out of Penetang Harbour trolling for trout and salmon. I was in 140' of water south of Giants Tomb and was marking fish and bait from 50' down to 100'. I set a chrome j plug 80' down and trolled through a bait ball with a large fish arch. The rod released from the downrigger but there didn't seem to be any action on it. For the first 20 feet it felt like I was pulling up the 10lbs rigger ball then I felt a kick and the fish took some line. The fish surged a few times as I brought it to the surface. I was expecting to see a trout on the end of my line but I was supprised to see a 15-20lbs muskie. I got the hook out and released it and it swam away strong. Has anyone else caught a muskie this deep?
