Marine and Freshwater Biology
Why Study Marine and Freshwater Biology at U of G?
Marine and Freshwater Biology 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 in the field and the lab.
 Conduct Research on Ocean and Lake Sustainability
Study freshwater and marine environments and the aquatic organisms that call them home from both biological and physical science perspectives, with a focus on sustainable management and conservation.
 Access the Hagen Aqualab
Take advantage of the University of Guelph’s state-of-the-art aquatic research facility, the Hagen Aqualab, which houses a wide variety of flora and fauna from arctic, temperate or tropical climes in simulated marine, brackish and freshwater habitats.
 Gain Technical Skills
Learn hands-on skills from global leaders in aquatic research in both on-campus research facilities and through field courses in arctic, tropical and temperate regions. Exchange programs are also available in collaboration with universities around the world.

Hear From a Marine and Freshwater Biology Student and Graduates
As an international student, the Marine and Freshwater Biology program allows me to gain hands-on experience and education directly in the field without compromising my passion for marine sciences. The co-op program has also been extremely beneficial in gaining hands-on experience with fish husbandry and lab techniques, which benefit me greatly in future opportunities.
During my undergraduate studies, I completed five diverse co-op placements across four locations. These experiences included working at a National Wildlife Area in Saskatchewan, on an Arctic charr farm in the Yukon, conducting Wildlife Habitat Assessments in Northern Ontario's boreal forests, and researching algae on the Great Lakes. These opportunities were pivotal in helping me identify my career interests post-graduation. The co-op program equipped me with practical skills and prepared me to succeed in the marine and freshwater industry!
