Marine and Freshwater Biology

The Marine and Freshwater Biology major capitalizes on Guelph’s recognized excellence in aquatic research. In this major, you will build upon core courses in ecology, evolution, genetics, physiology and zoology as you study freshwater and marine environments and work with aquatic organisms experimentally in the field and the lab. You will also look at the ecology of these systems from both biological and physical science perspectives as well as consider management and conservation issues. You will have the opportunity to participate in field courses in arctic, tropical and temperate regions. There is also ample opportunity to participate in exchange programs with Universities in Europe, New Zealand, Australia and Fiji. The state-of-the-art Hagen Aqualab on campus allows researchers and students to simulate global aquatic environments and maintain a wide variety of marine and freshwater flora and fauna in Guelph. This program prepares students for post-graduate work in the aquatic sciences, and provides a sound scientific background for students wishing to pursue careers in biology, management and conservation, aquaculture, biotechnology, education, and research either in government or private sectors.
