Precision and Bias of Three Bigmouth Buffalo Aging Structures
North American Journal of Fisheries Management, Volume 43, Issue 3, Page 646-655, June 2023., 2023 Abstract The Bigmouth Buffalo Ictiobus cyprinellus is a long‐lived catostomid with ecological and commercial harvest value. Management of Bigmouth Buffalo relies on accurate age data for population dynamic assessments (recruitment, growth, and mortality), but between‐reader precision of nonlethal aging structures compared to otoliths has not been ...
