Dominique P. Bureau became interested in aquaculture when he was an undergraduate student visiting Thailand on an exchange trip. He saw fish thriving in flooded rice field and became intrigued about the possibility of integrating fish production with agriculture production to improve the productivity of agricultural lands and help provide a good source of nutrition to a rural population. Upon completing his degree, he returned to Thailand to work on a MSc research project on this topic. He soon realized that nutrition and feed formulation were key factor in productivity in fish culture. He decided to make this the focus of his academic career and came to the University of Guelph in 1992 to work with Dr. C. Young Cho, one of the world leading experts in this field. Over the past 20 years, Dominique developed broad research interests that included studying nutrients requirements and utilization (essential amino acids, phosphorus) by different fish species, the development of cost-effective feed formulation, the evaluation of the nutritive value of economical feedstuffs, the management of environmental impacts of aquaculture operations, and the development of mathematical models of growth and nutrient utilization for fish and shrimp. One of the long-term objectives of his research program is to improve our understanding of nutrients utilization and deposition and, in turn, develop approaches to describe and predict the growth, feed and nutrient requirements, and waste outputs of fish and shrimp.
