Development of an age estimation method for Grass Carp from North America

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: July 15, 2025 | Last Modified: 20250124
The development of a reliable method of age estimation for Grass Carp is necessary for the successful management of this invasive species. Multiple federal and state agencies with assistance from commercial fishers collected adult Grass Carp from 2012 to 2018. Ossified parts were collected from these fish, and age estimates from them were compared to develop an age estimation method. Here we provide the data used in that effort.
