Check out this huge round goby caught by @tjcolvin.bsky.social, @hanakal.bsky.social, and me in lac Saint-François last week for @tjcolvin.bsky.social’s PhD project. It measured a whopping 125 mm! #invasivespecies #roundgoby

I use spectrophotometry to measure chlorophyll-a on tiles at the bottom of my goldfish mesocosms. The chlorophyll-a concentrations are used as a proxies for algal growth to better understand how goldfish invasions impact benthic algae. #freshwaterbiology #invasivespecies #goldfish #algae

Goldfish generate turbidity (cloudiness) by suspending sediment when they feed. This decreases sunlight penetration in the water and negatively impacts native macrophytes and visual predators. I use a turbidimeter to accurately determine the turbidity in my mesocosms from water samples.

I use this fluoroprobe to measure the concentrations of green algae, bluegreen algae, diatoms, and cryptophyta in each of my mescosms to see how goldfish impact the algal composition of a shallow pond ecosystem.

Each mesocosm in my goldfish experiment contains 0-6 goldfish. Notice the turbidity difference between a mesocosm with 6 fish and one with 0 fish below!

This is my experimental setup at Gault Nature Reserve in Mont-Sainte-Hilaire, QC. Each goldfish is measured before being added to one of the 36 experimental mesocosms. We record different parameters to measure the impacts of goldfish on these artificial ponds, including turbidity and algae growth.
