Targeted sampling for channel darter (Percina copelandi) in the lower Ottawa River and Little Rideau Creek, Ontario, 2010 and 2011 / by Jason Barnucz and Scott M. Reid.: Fs97-13/1357E-PDF

"In July 2010, October 2010, and August 2011 surveys were completed to determine the distribution of Channel Darter (Percina copelandi) in Little Rideau Creek and the Ottawa River. A combination of gears was used for these surveys including backpack electrofishing, seining, and trawling. In July 2010 three sites were sampled in Little Rideau Creek with a backpack electrofisher. Sampling effort ranged from 1172 to 2348 seconds. Twelve fish species were captured in including Cutlip Minnow (Exoglossum maxillingua) (98 specimens). In October 2010 two sites from July 2010 were resampled with backpack electrofishing and seining. Eleven species were detected during resampling, including Cutlip Minnow (16 specimens) and Channel Darter (2 specimens). In August 2011 15 sites were sampled along the Ottawa River between Voyageur Provincial Park and the City of Ottawa. Fishes were collected using three consecutive passes of a mini-Missouri trawl over a 100 m transect. Eighteen species (662 individuals) were detected including Channel Darter (135 individuals). Channel Darter was collected from 14 of 15 sampling sites"--Abstract, page v.
