Fish Movement in the Welland River Watershed

We continue to monitor diversity and relative abundance of fishes in the Welland River and Oswego Creek (with the Niagara Peninsula Conservation Authority and Niagara Restoration Council) using various active sampling techniques, radio-telemetry and a long-term publicly assisted mark-recapture study.  This project has been ongoing since 2001.


On November 5th 2014, Biotactic and the Niagara Peninsula Conservation Authority (NPCA) conducted a qualitative fish sampling survey using a seine net in the Welland River Watershed for Take Our Kids to Work Day. The main objective was to engage and educate youth with hands-on sampling techniques and fish identification, with emphasis on species at risk and their importance.


In 2012, Biotactic continued sampling efforts with the NPCA to monitor fish movement in the Welland River and it's tributaries. We have adapted standardized methods of seining and determined trap nets are not the best sampling technique in the lower Welland River due to flow reversal and water velocity.



Biotactic conducted a study on fish populations in Frenchman's Creek, Drapers Creek and Coyle Creek to assess changes in species distribution and diversity after the removal and/or remediation of fish barriers. In addition, we also found a stinkpot turtle, which is a species at risk, last found in the region since 1979!
