Did you know that fishways can act as ecological traps? Video of 45 instances of juvenile #NorthernPike exiting a fishway to get eaten by adults waiting upstream. Bearhole fishway, City of Dawson Creek. Camera: BRAVO M2 fish monitoring system.

LIVE 24/7 feed from our underwater cameras in the Grand River, Kitchener, and in the #Thornbury Fishway in the Beaver River. Lots of activity with Cyprinids and Bass in the grand and #ChinookSalmon migrating from Lake Huron:

Introducing the Biotactic Research Artificial Intelligence Network (BRAIN). In use since 2021 the BRAIN accurately counts fish, differentiates upstream/downstream movement and true/false passage. Near real time or post collection processing. Info at https://t.co/diLQb1H901 #ai

Here's a short clip of a #smallmouthbass predating a cyprinid inside the Mannheim weir fishway on the Grand River. Recorded with a BRAVO fish monitoring system. You never know what you'll find!

While we mainly work with fish, we occasionally get the opportunity to do some fun things with freshwater mussels including monitoring fish-mussel interactions and SAR relocations. Can't wait to do more! #WorldBivalveDay

Every fall Biotactic conducts redd counts in the Saugeen River and its tributaries to monitor #ChinookSalmon spawning. Upstream of the removed Truax Dam counts are performed with a drone. How many fish and redds do you count in this video? #fieldwork https://t.co/btX09kkMxA

Year 2 post #damremoval biomass monitoring complete! Staff just returned from 4 weeks of sampling across the #Saugeen River watershed. 70 sites electrofished and thousands of fish weighed and measured. Can't wait to analyze the data! #fieldwork

We radiotagged another 50 #RainbowTrout this weekend. 300 have now been tagged since 2018 and their movement is tracked year-round to monitor the effects of #dams and a #damremoval on passage throughout the #Saugeen River watershed. Check out the process- condensed to 1.5mins!

The #RainbowTrout have arrived! Watch the #fishmigration at the #Thornbury fish ladder on our 24/7 live feed: https://t.co/zmjBNGqKtA

Final set of baseline #radiotracking data following #RainbowTrout migration is now up- part 3 (spring 2019) of a long-term #damremoval monitoring study in the Saugeen River. The Truax Dam was removed Aug 2019 to increase #fishpassage across the watershed

Spring #fieldwork season has definitely arrived in full force this week. Love being able to spend days back outside collecting really interesting data for some amazing projects!

[Biotactic Inc. @BiotacticInc]

Monday- a great tracking flight with @FlyOwenSound. Tuesday- installed a new fixed #telemetry receiver station monitoring #fishpassage at a key #dam and #fishway, bringing our total to 6 across the river
Thursday- stay tuned for an exciting announcement!
