Data for impacts of introduced Alewife and White Perch on growth of Rainbow Trout in the Ashokan Reservoir, Catskill Mountains, New York

This dataset contains the results from aging and back-calculation of length-at-age of scale samples from 502 Rainbow Trout captured in the Ashokan Reservoir between 1952 and 2017. The first six columns contain collection information including an assigned fish number, the year and period of capture, the basin of the Ashokan Reservoir from which a fish was captured, and the length and weight of the fish when it was captured. The final three columns present results from the aging and back-calculation procedures. Multiple rows of information often correspond to an individual fish and are designated by the "Fish number" column.
