"In 2010 and 2013, surveys were conducted along a 19.4 km reach of Lyons Creek to assess the abundance, distribution, and associated habitat of Grass Pickerel and Lake Chubsucker. In 2010, 20 sites were sampled with a straight (2 sites) or bag seine (18 sites). Sampling effort was variable, between two and five hauls at each site. In 2013, 16 sites were resampled with five consecutive hauls of a bag seine. In 2010, 19,399 individuals were caught, representing 23 species. Grass Pickerel was detected at 20% of sites and Lake Chubsucker was detected at 25% of sites. In 2013, 1,717 individuals were caught, representing 20 species. Grass Pickerel was detected at 19% of sites and Lake Chubsucker was detected at 25% of sites. Most sites with Grass Pickerel and Lake Chubsucker had more than 50% aquatic vegetation cover (emergent and submergent vegetation). Based on the 5-haul removal sampling dataset (n = 19), 58% of species detections occurred during the first haul. Detection of Grass Pickerel always occurred in the first two hauls; however, Lake Chubsucker was more difficult to detect with 40% of detections occurring on the final haul"--Abstract, page vi.
