Project Title:
Optimizing IMTA species component stocking densities and infrastructure orientation
to maximize overall system efficiency (D2P4)

Project Description:
In light of the differing regional IMTA developments in Canada, it is clear that the design and engineering challenges manifested by adapting existing finfish aquaculture systems to support IMTA integration are considerable and varied. Hydrographic processes will dictate how dissolved nutrient and particulate plumes flow among these differing major infrastructure components, defining how best the IMTA production systems should be designed/configured in order to fully capitalize on the dispersion pathways of these waste streams. However, the interception of these streams by the various extractive species can, in themselves (at commercial production levels), affect how efficient the resulting IMTA system will be. Proximity to the fed (fish) component, density of the grow-out structures (nets, cages, trays), vertical and horizontal orientation with respect to the flows, within-production unit densities, and spatial/temporal integration of multi-species/multi-year classes within each type of IMTA system are all issues that need to be addressed in order to ensure continual and optimal system performance. This work will start in years 4-5 of CIMTAN with two MSc students and will compare the effects of system configuration on extractive performance of “intensive” IMTA systems on the west coast and “extensive” IMTA systems on the east coast.
(Intensive (British Columbia) and extensive (New Brunswick) IMTA farm sites. These systems will be compared as to their relative efficiencies in nutrient recapture. - Credits: Shawn Robinson)
