Muskie is a big challenge for visiting anglers as they are the largest fish found in Lake Nosbonsing. The Ministry of Natural resources have stipulated that muskie measured at less than 48 inches cannot be kept. This is to preserve fish stocks for future generations and ensure a larger muskie will always be found in the waters of Nosbonsing. It is thought that muskie weighing more than 50 pounds have been pulled out of the lake!
Popular spots for catching muskie on Lake Nosbonsing are Sunken Island and the Narrows. Fishing for pike is also gaining popularity in the area. Smaller pike can be found readily in the spring, however, pike as large as 38 inches are found every year by the most skilled anglers and often win the annual pike tournament.
Nosbonsing is also home to bass, with the largemouth and smallmouth species found in good numbers. Smallmouth can be caught in most areas of the lake, however, the best chance of catching largemouth will present itself in Railway Bay, located on the north shore.
