Research: Integrated Multi-Trophic Aquaculture (IMTA) consists of cultivating inorganic and organic extractive species in close proximity to traditionally farmed species to mitigate nutrient loading as a means to promote sustainable aquaculture practices. The purpose of my project is to understand the spatio-temporal dynamics of particle depletion by Mytilus edulis that removes particulate organic matter within an IMTA system.
Laboratory tests were conducted for calibration purposes and revealed that the LISST-100X (Laser In-Situ Scattering and Transmissometry) instrument which measures particle size distributions (2.5 – 500 µm) based on laser diffraction is an effective tool in quantifying particles within certain size ranges and concentrations.
Multiple IMTA sites in the Bay of Fundy are currently visited monthly to characterize particle fluxes at the inflow and outflow of mussel cages adjacent to occupied and unoccupied salmon net-pens. Subsequently, laboratory tests are underway to determine the effects of mussel size and density on depletion rates.
The data collected will offer valuable insight into understanding the bio-mitigation capabilities of the blue mussel within ecosystem-based aquaculture system.
