520 |a"The spread of the invasive Round Goby (Neogobius melanostomus) was assessed as a significant threat to those populations of Channel Darter (Percina copelandi) identified by the Committee on the Status of Endangered Wildlife in Canada as the Lake Ontario designatable unit. However, expert-based threat assessments require validation through field research and monitoring. Between 2001 and 2019, electrofishing surveys to detect and monitor the two species were undertaken along two Lake Ontario tributaries: the Trent River (15 sites) and Moira River (17 sites). A total of 1,280 Channel Darter and 3,104 Round Goby were captured from the Trent River across all sample events between 2001 and 2018. Round Goby co-occurred with Channel Darter at 7 sites. Four Channel Darter and six Round Goby were captured from the Moira River in 2019. Round Goby was only detected below the first dam in Belleville; Channel Darter was not detected at this site. In the summer of 2019, angling surveys were undertaken on Moira (25 sites) and Stoco (22 sites) lakes - potential baitfish introduction sites. Round Goby was not detected in either lake"--Abstract, page vi.
