Stokesbury Lab Research

tl_files/sites/cel/Our Team Photos/Delhaven Wharf, Kings Co, NS.jpg

The primary aim of the Coastal Ecology Lab is to quantify how anthropogenic development impacts coastal ecosystems with a focus on fish behaviour and migration, and the role fish play in energy transfer within these ecosystems. This new knowledge can be used to mitigate the negative effects of anthropogenic development on coastal ecosystems by employing more effective resource management strategies.
