TRCA Electrofishing Data 2000-2018


This dataset contains the species fish caught using boat electrofishing along the TRCA Lake Ontario shoreline from 2000 to 2018. The fish are monitored for a variety of reasons including routine long-term monitoring for the Remedial Action Plan, pre/post construction monitoring, Asian Carp surveillance. Standardized boat electrofishing sampling usually occurs for 1000 seconds (effort) although there are often shorter/longer sampling times depending on the reason for sampling. The first 20 fish of each species are individually measured and weighed before they are put back into the water. The remaining fish for each species are measured together in bulk. The "bulked" fish are listed as individuals with an average length and weight (e.g. 27 Emerald Shiner weighed 36 grams; therefore, there would be 27 individual Emerald Shiners listed that each weighed 1.33 g).
