Dr. Huyben is the Assistant Professor of Aquaculture at the University of Guelph in Ontario, Canada. He completed his PhD at the Swedish University of Agricultural Sciences in Uppsala, Sweden with a focus on yeast as a protein source and impacts on the blood physiology and gut microbiome of farmed rainbow trout and Arctic charr. Since then he pursued postdoctoral research at the University of Stirling within the Institute of Aquaculture where he investigated environmental stressors and omega-3 fatty acids requirements of farmed Atlantic salmon. He has also collaborated on aquaculture projects in Norway, Finland, France, Italy and across Canada with a range of research on fish farming technologies, aqua-feeds and pathogen control.

Since June 2020, Dr. Huyben is employed to contribute 40% to research, 40% to education and 20% to industry liaison between the Canadian/Ontario aquaculture sector and the University of Guelph. Dr. Huyben is the lead instructor for a 3rd year undergraduate course called Aquaculture: Advanced Issues (ANSC*3050) and contributes to other undergraduate and graduate courses at the Department of Animal Biosciences. His research focuses on the effects of feeding omega-3 fatty acids, single-cell proteins and probiotics on the growth, immune response and gut microbiome of salmonid fishes, especially rainbow trout and Atlantic salmon. He mentors a handful of grad students in aquaculture projects that involve nutritional and molecular skills and Dr. Huyben plans to train more HQP to become future aquaculture scientists and professionals. He routinely collaborates with feed and fish farming companies as well as government agencies, both locally, nationally and internationally.
