Long, J.M. and A.A. Nealis. 2017. Comparative precision of age estimates from two southern reservoir populations of Paddlefish (Polyodon spathula (Walbaum, 1792)). Journal of Applied Ichthyology 33:819-820. DOI: 10.1111/jai.13394


We sought to determine whether location and sex affected age precision estimates between two southern, reservoir populations of paddlefish (Polyodon spathula (Walbaum, 1792)). From 589 paddlefish collected in Grand Lake and Keystone Lake, Oklahoma in 2011, we estimated age from dentaries using three independent readers and compared precision with coefficient of variation between locations and sexes. Ages were more precisely estimated from Grand Lake and from females.
