Co-chaired a successful session with @tjcolvin.bsky.social at @scas-scsa.bsky.social / @iaglr.bsky.social 2026 on the impacts of invasive species in Great Lakes systems! Topics included #PinkSalmon #RedSwampCrayfish #RoundGoby & #NilePerch ft PhD research from @biomcgill.bsky.social

Registration is open!!! We are extremely excited about this year's symposium and look forward to hearing about all the amazing research conducted in Quebec. #AFSQCS2026

Calling aquatic invasion scientists! @veronicagroves.bsky.social and I are co-chairing the session "Invasive Species in Great Lakes Systems" at the 2026 @iaglr.bsky.social - @scas-scsa.bsky.social joint conference in Winnipeg May 25-29th and are looking for talks to feature!

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.

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

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!

Freshwater sponges are ancient colonial invertebrates found in virtually any lake or river. The photo below shows Eunapius fragilis. Water enters through tiny pores (ostia), passes through chambers lined with collared cells that filter particles from it, and then exits through large pores (oscula).

Our AFS Ex-Comm members attended the third annual SCAS conference in Hamilton (@scas-scsa.bsky.social)! 🎉 Happy to keep connecting with the fish community and sharing our passion for aquatic science. 🐟🌊 Hope to see you at our third AFS symposium! 👀 #AFSQCS2025

You heard it from our treasures first... how do YOU communicate science? Sign up for the symposium and let us know! Nos trésors vous l'ont dit en premier... comment communiquez-vous la science ? Inscrivez-vous au symposium et faites-le nous savoir ! #AFSQCS2025
