Exploring a multi-trophic aquaculture system containing non-fed species
The focus of my research is exploring the potential for a multi-trophic aquaculture involving extractive, or non-fed, species. Multi-trophic aquaculture is a method of food production whereby species from different trophic levels are grown in association with each other. The aim of this is to increase the yields of the system via the recycling of nutrients between species, resulting in more efficient growth as well as a decrease in the release of potentially harmful nutrients.
Whilst most aquaculture systems tend to focus on a species that requires feeding, such as salmon, my aim is to research the potential for combining non-fed species in a multi-trophic system. At present, I am working to co-cultivate the blue mussel (Mytilus edulis), an important aquaculture species in Sweden, with seaweeds such as the sugar kelp (Saccharina latissima).
