Summary

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.

Purpose

Scientific research and anecdotal observations both suggest that naturalized populations of Rainbow Trout in the upper Esopus Creek watershed (New York) have declined over the past few decades. One hypothesis that has been put forth to explain this decline relates to the introduction of two invasive fishes in the Ashokan Reservoir which may be competing with Rainbow Trout for food resources. These data are used to determine if the growth or length-at-age of Rainbow Trout in the Ashokan Reservoir has decreased following the introduction of two invasive fishes that may be competing with Rainbow Trout.
