Forward Facing Sonar Webinar and Open Table Discussion Wed. Feb. 11, 2026 | 12 pm EST Following the expert presentations there will be time for group discussion. We will also share more about a symposium planned for the upcoming annual meeting. www.xcdsystem.com/afs/store/re...

Just maxin’ and relaxin’ with our buddies in a pool…swimming ‘round wood debris just to stay cool… Stream-resident Lahtontan Cutthroat Trout moved little during streamflow recession and base flow. Follows restricted-movement paradigm. #JamesSimmons #SummitLake link.springer.com/article/10.1...

There are about 532,938 acres of #GreatLakes coastal wetlands - some 833 square miles - that provide habitat for nearly 80 species of fish species at some point during their life cycle. Yellow perch, pike, and bass all often start out their lives in these nurseries! #WorldWetlandsDay

A short feature from @trentuniversity.bsky.social on our research using @innovasea.com predation-sensing telemetry tags to study fish ecology! www.trentu.ca/news/story/2...

Oxygen supersaturation has negligible effects on warming tolerance across diverse aquatic ectotherms 14 ectotherms. 24 experiments. 147 CTmax trials. Over 1,450 animals. Results? Oxygen saturation is unlikely to protect most water-breathers from heatwaves. @graham-raby.bsky.social

Blackchin shiner exposed to warming and predation risk exhibit changes… Some like it hot. At least warmer, supporting notion that acclimation temps increase thermal tolerance. Check out the CTMax comparisons used! Anyone feel Thermal Maxima should be a spell from Harry Potter? #VeronicaGroves

I now know that there is a #freshwater bivalve in #Alberta that is called a fatmucket, and that made my day! Credit: @inaturalist.bsky.social

A common claim is that zebra mussels "clean" lakes. They can certainly clear the water column but also create conditions that reduce oxygen & promote toxic algal blooms: phys.org/news/2021-06... www.canr.msu.edu/news/telecou... cdnsciencepub.com/doi/10.1139/... www.greatlakesnow.org/2021/07/rese...

CONGRATULATIONS! Larkin Award - MSc Runner Up #CaliyenaBrown 🐟 [Robert Lennox, #DalhousieUniversity] 🐟 Caliyena’s research aims to better understand migration and mortality drivers of #AtlanticSalmon kelts within the inner #BayOfFundy to improve recovery strategies.

CONGRATULATIONS! Larkin Award - MSc Winner #KevinAdeli 🐠 [Bryan Neff, #UniversityWaterloo] 🐠 Kevin’s thesis found thiamine deficiency stands as a threat to the cardiac health of #ChinookSalmon, potentially affecting their ability to undergo spawning migrations.

CONGRATULATIONS! Larkin Award - PhD Runner Up #AnneHaley 🦈 [Steven Cooke, #CarletonUniversity & Jake Brownscombe, #DFO] 🦈 Anne’s research on #CaribbeanReefSharks looks at how the species uses their resource landscape using telemetry, isotopes and abiotic data around #Turks&Caicos Islands.

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.
