Presentation Abstract
Estimating the age of fishes is a key component of fisheries management and therefore understanding the validity of estimation methods is essential to appropriate management. A common method of age estimation requires the counting of annual 'growth rings', or annuli, found in cross sections of hard structures such as fin rays. Typically, as a measure of quality control, a consensus estimate is reached between two individual readers. In this study, we use the fin rays of Muskellunge anal fins to determine if there is a difference in accuracy between independent age estimates and estimates reached by consensus.
