Some more great talks at #GLATOS2026 in Sarnia last week! @chris-on-fish.bsky.social and Leah Howitt

Really enjoyed the 35th Rice Lake Comparative Physiology & Biochemistry Workshop this weekend. Big shout-out to @graham-raby.bsky.social lab members for sharing some great science.

Great to be at the @amfisheriessoc.bsky.social Ontario Chapter AGM last weekend! Huge congrats to members of the @graham-raby.bsky.social lab for their excellent presentations. Emma won the Al Dextrase Award for best poster! @mitchellshorgan.bsky.social

How useful is underwater video as a fisheries assessment tool in freshwater? @jacobbowman.bsky.social asked this question for his honours thesis, by comparing video against other ways of counting fish. Editor's Choice in TAFS: academic.oup.com/tafs/advance...

How useful is underwater video as a fisheries assessment tool in temperate freshwater ecosystems?

ABSTRACTObjective. Remote underwater video (RUV) is a noninvasive survey technique that has long been used in marine ecosystems and is now gaining interest

CONGRATULATIONS! Larkin Award, PhD Winner #BradleyHowell 🪼 [Graham Raby, #TrentUniversity & Steven Cooke, #CarletonUniversity] 🪼 Bradley’s research focuses on using telemetry and respirometry data to assess #predatorprey interactions and movement patterns that raise predation risk.

Hard to believe it’s already been two years since I finished my master’s. I am grateful for the mentors, field days, and late nights that shaped where I am today.

Just came across this method from 1970: researchers used a periscope-like device frozen into the ice to watch fish under the surface. Such a clever way to study winter ecosystems! 🐟❄️ From Magnuson & Karlen (1970). #FisheriesScience doi.org/10.1139/f70-...
