Developing new techniques for the evolution of aquaculture-based
seafood is the goal of the Integrated Multi-Trophic Aquaculture (IMTA)
program based out of the St. Andrews Biological Station and the
University of New Brunswick in Saint John.
Under the leadership of Dr Shawn Robinson (DFO) and Dr Thierry Chopin
(UNBSJ), the program team promotes the practice in which the by-products
(wastes) from one species are recycled to become inputs (fertilizers,
food) for another so that the entire operation becomes more socially
acceptable, economically profitable and environmentally benign.
The concept revolves around fed aquaculture (e.g. fish, shrimp) being
combined with inorganic extractive (e.g. seaweed) and organic
extractive (e.g. shellfish, deposit feeders) aquaculture to create
balanced systems.
The research has been ongoing in the Bay of Fundy with the salmon industry for nine years.
