Seasonal variation in the composition of fishes caught during trawl-based surveys of Little Bear Creek, Ontario / Scott M. Reid, Anita LeBaron, and Jason Barnucz. : Fs70-5/2016-070E-PDF

"Little Bear Creek, a tributary of Lake St. Clair, is classified as an agricultural drain and has been identified for maintenance. The creek supports six fish species at risk including Pugnose Shiner, Lake Chubsucker, Grass Pickerel, Blackstripe Topminnow, Spotted Sucker, and Pugnose Minnow. Project staging, fish exclusion methods, and timing windows for in-water works have been proposed as mitigation to minimize drainage work impacts. To assess whether the proposed timing window would minimize the risk of direct mortality to fish species at risk, a trawl-based fish survey was completed over three different time periods (summer, fall and early winter) in 2015" - Abstract - p.iii.
