Summary
A total of 236 Black Carp were collected throughout the year from 2017-2019 by incidental captures of commercial fishers and biologists. Capture date, river basin of capture location, and coordinates were recorded for each Black Carp captured. A subsample of 119 Black Carp varying from 429-1268 millimeters total length were compared for the precision of annuli counts by two experienced readers for the ossified two anterior pectoral fin rays, the ossified anterior dorsal fin ray, sectioned vertebrae, and lapilli otoliths for selection of a single structure based on percent exact agreement, coefficient of variation, and age-frequency plots.

The data provides information about which structures were collected to be used for counting annuli. The time of year when the fish was collected was also recorded, which aids in determining whether or not an annulus may have been seen at the edge of a structure. The total length was recorded to allow for back-calculation of length of the fish. The river basin was recorded to allow for examination of differences between growth from different river basins. The coordinates provide information on the habitat preferences of black carp.
