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.
