520 |a"In September and October of 2021, trawling surveys were completed across four eastern Lake Ontario coastal wetlands to update distribution records for the Threatened Pugnose Shiner (Notropis anogenus) and describe habitat characteristics associated with the species. Forty-four sites were sampled in Presqu'ile Bay (n = 13), Wellers Bay (n = 11), West Lake (n = 13), and East Lake (n = 7). Sites were located in areas of vegetated habitat near the sites of previous wetland fishes at risk surveys. Fishes were collected using three consecutive passes of a Mamou (surface) trawl over a 50 m transect. Eighteen species (4,085 individuals) were detected, including Pugnose Shiner, Bridle Shiner (Notropis bifrenatus; Species at Risk Act (SARA): Special Concern), and four recreationally important species. Pugnose Shiner (363 individuals) was collected from 70% of sites across all water bodies; the species was most abundant in West Lake and present at all sampling sites. Bridle Shiner (277 individuals) was collected from 64% of sites across all water bodies; the species was most abundant in East Lake and present at 86% of sampling sites. Length-frequency distributions indicate ongoing recruitment and multiple age classes for both species. At Bridle Shiner and Pugnose Shiner collection sites, water clarity was high, water depths were between 0.7 and 1.8 m, substrate material was largely organics and sand, and submerged vegetation cover was dense. Dominant submerged plant taxa were wild celery (Vallisneria americana) and stonewort (Chara spp.)"--Abstract, page vii.
