Last week our field team investigated the effects of low water levels in the St Lawrence River. Shown left to right: @briellecomartin.bsky.social, @ivanakomendic.bsky.social & @tjcolvin.bsky.social Joining them was @ecoinvasions.bsky.social. The land on which they're standing should be under water.

Sampled an incredibly diverse site of freshwater mussels in the St. Lawrence River! @ricciardilab.bsky.social

A great week at Lac Témiscouata for @ivanakomendic.bsky.social fieldwork investigating zebra mussel associations with different substrates & macrophytes

AFS Bioblitz Recap #BlitzTheGap 🎥🎥🎥🎥

Was thrilled to find so many freshwater sponges during a practice dive in the St. Lawrence River, including some growing on unionid mussels! #freshwatersponges

Concordia is ready to represent the AFS...So many external rep applicants —we’re gonna need a bigger tank Concordia est prête à représenter AFS...Tellement de candidats pour le poste de représentant externe —on va avoir besoin d’un plus grand aquarium 🐠

Sampling in the Ottawa and St. Lawrence Rivers for @vanmierlo.bsky.social’s fieldwork, targeting invasive spinycheek crayfish #invasivespecies #crayfish

Join us Saturday, July 19, 2025, for a day of biodiversity fun on Île Perrot to #BlitzTheGap with iNaturalist! 🌿🐟 We’ll be targeting understudied aquatic species—plus there’ll be prizes, food, and great company. We hope to see you there!

The zebra mussel invaded the Richelieu River in the mid-1990s, despite a suboptimal calcium concentration (18 mg/L). After 25 yrs of exposure to fouling, unionid diversity & abundance have eroded to the same extent as in invaded calcium-rich habitats. See our paper: cdnsciencepub.com/doi/10.1139/...

Great article to read before the upcoming #IAGLR25 conference! @briellecomartin.bsky.social understands the spirit of what I'll be sharing in my improv workshop with this advice: "DO: Present your research (poster or talk) with confidence DON’T: Underestimate yourself"

The AFS community can rock more than waders and rubber boots! This year's symposium was a fashion show… and this isn’t even the whole look! More sneaky fits to come:) Il est CLAIR que la communauté AFS peut porter autre chose que des cuissardes et des bottes en caoutchouc. #AFSQCS2025

Wow, what an amazing event! 🎉 Huge thanks to all the presenters, attendees, and artists for making our 3rd annual symposium truly unforgettable. It was incredible to see the fish community come together! 🐟💙 Stay tuned for more recaps, and share your moments with #AFSQCS2025! 🏆✨

Congratulations to my lab mate @ivanakomendic.bsky.social on passing her QE! 🍻🤍 #PhDcandidate

New #OpenAccess paper on the use of #nonlethal chemical cues on minnow behaviour🐟 ➡️ onlinelibrary-wiley-com.proxy3.library.mcgill.ca/doi/full/10.... as part of my PhD research @biomcgill.bsky.social

Introducing our new director Professor Anthony Ricciardi @ecoinvasions.bsky.social with a video and a message of some of his hopes for the future!

In light of this year's theme, we are asking McGill Biology students how they communicate science. Regardez ce tik tok pour voir comment ils le font et inscrivez-vous à la conférence pour nous dire comment VOUS communiquez la science. vm.tiktok.com/ZMkgFhK8W/

📢 Mark your calendars! The 2025 Symposium: Communicating the Current is happening on March 25th Discover, learn, and connect with Quebec's vibrant aquatic research community 📅 Sign up now using the QR code below! #AFSQCS2025 #CommunicatingTheCurrent linktr.ee/AFSQC

Hello Blue-Sky!!🐟 We are the Quebec Subunit of the @amfisheriessoc.bsky.social! We are a group of students from various Quebec universities with a common goal of communicating, collaborating and promoting aquatic and fisheries science! We are excited to share what we have been up to!🌊
