Studying Hamilton’s harbour invaders

goby researchers

Erin McCallum, Ryan Caldwell, Pauline Capelle and Olivia Petric work in Sigal Balshine's Aquatic Behavioural Ecology Lab. They spend two days every two weeks at Hamilton Harbour working with the invasive round goby fish species.


A team of students in Sigal Balshine’s Aquatic Behavioural Ecology Lab is working to better understand the invasive round goby fish found in Hamilton Harbour.

The students, both undergraduate and graduate, catch gobies at several locations around the bay and in Cootes Paradise. They then record the area in which the fish were caught, vital statistics such as their sex and size and water quality information.

The Aquatic Behavioural Ecology Lab researches the evolution of cooperation, parental care and breeding, sperm competition, species introductions and extinctions and the effects of contaminant exposure.

Pauline Capelle, in her third year studying biology and psychology, blogs about the lab’s work as part of the School of Graduate Studies’ new blog series.
