An update of river darter (Percina shumardi) distribution, relative abundance, life history traits, diet and habitat in Canadian waters / Pratt, T.C. ... [et al.]. : Fs70-5/2015-011E-PDF

The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) has requested an update of the status of River Darter in Canada. This document will follow the three biogeographic zone convention to aid in the transfer of information to the COSEWIC process. As the Department responsible for this species, Fisheries and Oceans Canada (DFO) is required to summarize available information on this species. As many of the Canadian records of River Darter are quite old, in preparation for the COSEWIC status report, DFO revisited many of the historic sites and sampled additional waterbodies, where possible. This manuscript reports on the findings of those targeted surveys, along with incidental captures from across the species range, including an assessment on the distribution of River Darter and its relative abundance, an update of life history characteristics, diet and identification of the characteristics of River Darter habitat.
