Dr. David Huyben is from a farm in Southwestern Ontario and completed his BSc and MSc degrees at the University of Guelph. He went abroad to complete his PhD at the Swedish University of Agricultural Sciences in Uppsala, Sweden with a focus on the yeast protein and gut microbiome of farmed rainbow trout. Since then he pursued postdoctoral research at the University of Stirling within the Institute of Aquaculture where he investigated hypoxic stress and omega-3 fatty acids requirements of farmed Atlantic salmon. He has also collaborated on aquaculture projects in Norway, Finland, France and across Canada with a range of research on fish physiology, aqua-feeds and pathogen control.

Since 2020, Dr. Huyben started as the Assistant Professor of Aquaculture at the University of Guelph. His research program focuses on the nutrition, microbiome and health of farmed salmonid fishes, especially rainbow trout, lake whitefish and Atlantic salmon. Specifically, his studies involve feeding omega-3 fatty acids, yeast, insects and probiotics to fish and investigating their effects on the growth performance, immune response and gut microbiome using nutritional analyses, mass spectrometry, quantitative PCR and 16S rDNA next-generation sequencing. 

The aquaculture industry is faced with many challenges, such as using quality feed and mitigating disease outbreaks, in Canada and around the globe. Dr. Huyben's research aims to replace fishmeal and fish oil with sustainable ingredients (e.g. insects and plant oils) while meeting nutritional requirements of fish and improving immune defence and disease resistance. He routinely collaborates with feed and fish farming companies as well as government agencies, Indigenous groups and universities, both nationally and internationally with the aim to improve the sustainabillity, growth and resilience of the aquaculture industry.
