Tubenose goby (Proterorhinus semilinaris) eggs slowly growing over two weeks. The fry (or “goblets”) should hatch any day now! The father has been diligently nest guarding.
Sexual dimorphism in male (back) and female tubenose gobies! Collected from the upper St. Lawrence River.
Male tubenose goby (Proterorhinus semilunaris), with dark spawning coloration. Collected today from the upper St Lawrence River by Maddie Picard (@picard-m.bsky.social) and her field team.

We had a great time at the McGill BGSA Retreat at Gault Nature Reserve this past weekend! 🌲❄️ @picard-m.bsky.social @vanmierlo.bsky.social @biomcgill.bsky.social
Do you study the impacts of #InvasiveSpecies and plan on attending #SCAS_IAGLR2026? Consider submitting an abstract to our proposed session below ⬇️ ⬇️ ⬇️
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!
New study from our lab: Feeding efficiency (trophic impact) of goldfish varies with combinations of thermal & salinity conditions typical of urban ponds in north temperate regions. Salinity enhances efficiency at temperatures below the thermal optimum of goldfish. link.springer.com/article/10.1...
Effects of temperature and chloride salinity on the functional response of goldfish (Carassius auratus) - Biological Invasions
Freshwater animals released into temperate urban environments are increasingly subjected to the effects of elevated water temperatures (via climate warming) and salinization (via road salt application...

Highlights from my first field season with the amazing Ricciardi Lab team @ricciardilab.bsky.social! It has been such a joy learning about this new system, and getting to know my study species!
A beautiful fall day at the Gault Open Doors event 2025 talking to the community about aquatic invasive species 🐟🌱 @picard-m.bsky.social #goldfish #invasivespecies #aquaticecology #tubenosegoby #roundgoby #gaultnaturereserve
