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.
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!
