Examining the Environmental Pros and Cons of Integrated Multi-trophic Aquaculture (IMTA)

Supervisor team may include:

IMTA has several prospective benefits for salmon aquaculture; including the provision of alternative product(s) and the potential to offset the adverse effects of nutrient inputs. However, it is important to understand all of the interactions to ensure the benefits outweigh any possible negatives.

It has recently been suggested that current net cleaning activities in salmon culture may have the potential for adverse interactions in co-production with shellfish depending on the nature of the fouling communities and proximity of the farming operations.
Whether this might be a significant issue for IMTA/ polyculture operations needs to be investigated. There are two key project areas that have been identified: Project 1 - Impacts of net cleaning on co-culture species (performance & growth) and Project 2 – How close is too close? How far away must co-culture species be to beyond any influence of net-wash material.

Suitable for February or July start date.
