Research Assistant (Fish)

IISD Experimental Lakes Area (IISD-ELA) is the world’s freshwater laboratory. A series of 58 lakes and their watersheds in northwestern Ontario, Canada, IISD-ELA is the only place in the world where scientists can research on and manipulate real lakes to build a more accurate and complete picture of what human activity is doing to freshwater lakes. The findings from over 50 years of ground-breaking research have rewritten environmental policy around the world—from mitigating algal blooms to reducing how much mercury gets into our waterways—and aim to keep fresh water clean around the world for generations to come.

IISD-ELA is operated by the International Institute for Sustainable Development (IISD)—an independent think tank headquartered in Winnipeg situated on Treaty 1 Territory—the ancestral lands of the Anishinaabe (Ojibwe), Ininiw (Cree), Anisininew (Ojibwe Cree), Dene, and Dakota Nations, and the homeland of the Red River Métis Nation. The IISD-ELA field station is situated on the traditional land of the Anishinaabe Nation in Treaty 3 Territory and the homeland of the Métis Nation.
