Description of Dr. Gregor Reid's post-doctoral fellowship activities: Dr. Reid is a jointly appointed Post Doctoral Fellow with the University of New Brunswick and the Department of Fisheries and Oceans. He has pursued numerous works in aquaculture sustainability over the last decade, ranging from public extension to nutrient assimilative capacity; and routinely liaises with academia, industry, government, and non-government organizations on related topics. His Ph.D. research involved the investigation of novel methods to quantify water quality change from freshwater cage-based aquaculture (Great Lakes), exploring combinations of mass-balance nutrient modelling and automated monitoring. Presently, his Post Doctoral work involves the development of an overall flexible model for integrated multi-trophic aquaculture (IMTA) systems; incorporating aspects of nutritional ecology, Monte Carlo simulation, eco-exergy, bioenergetics and mass-balance modelling.

Some research highlights:
- Developed methods using instantaneous relationships of pH and dissolved oxygen to differentiate near-field phosphorus loaded from fish cages, from that of other anthropogenic sources in the Great Lakes.
- Refined spectrophotometric analytical techniques for the Aquaculture Centre (University of Guelph); achieving a lower detection limit for total phosphorus of 0.4 µg L-1 (method detection limit of 0.8 µg L-1).
- Co-developed a decision support tool for the licensing of freshwater cage aquaculture in Ontario.
- Modeled near-field 'nutrient plume' concentrations from rainbow trout cages.
- Application of Monte Carlo simulations to mass balance salmonid waste models; accounting for variation in proximate composition (diet) and digestibilities, as a means to quantify and qualify nutrient inputs for co-cultured species in IMTA systems.
