About the project

The future growth of the global aquaculture industry will demand development of new and sustainable marine feed ingredients with a high density and bioavailability of protein, lipid and other nutrients. Norway alone had an annual turnover of 1.6 million tons of fish feed in 2012.

The availability of fish meal and fish oil, traditionally used in fish feed formulations, are limited due to the carrying capacity of fish stocks and the industry is therefore to an increasing extent using plant based ingredients e.g. oilseeds, legumes, cereals. However, these ingredients can be used directly for human consumption and a more sustainable development of the aquaculture industry would be to explore the utilization of alternative marine animal resources not applicable as food.

This alternative biomass should also allow significant scale-up possibilities, preferably close to the site of aquaculture installations. Indeed, the current policy for research and development within this area is emphasizing the use of best available knowledge on marine ecosystem management of marine resources and maintaining ecosystem service functions, a principle termed ecosystem-based management (EBM). Key to this is environmental and social sustainability. Industrial requirements for future feed resource are potential large scale prospective, ecological sustainable production, a favorable nutrients composition and a low bioaccumulation of environmental pollutants.

Here we propose to use filter-feeding tunicates as a new biomass resource for salmon feed.
