Not the largest but the best battle. I caught this Sturgeon on the Ottawa River, Petawawa at dusk. I was fishing for Pickerel using a minnow, 1/2 oz sinker, Mitchell Ultralight rod 5'6" and Shimano Ultralight reel with Trilene 6 lb test, extra limp. The prize was 45" long and took me 45 minutes to net.
Best weight was a 28 lb Salmon form Lake Ontario.
Cheers.
