Fish feed from the forest to salmonids

There is an increasing interest from the fish farming industry to develop new feed ingredients to allow for sustainable growth. The SALMONAID project aimed to produce protein-rich ingredients based on side streams from the forest industry, intended to be able to replace both the fishmeal and soy based products currently used in fish feed.

Background and aim

Aquaculture meets an increased demand for seafood and is now seen as one of the most promising options for future protein production. But for this to be possible, we need to find solutions to the many challenges in which feed innovation is central. Reducing dependence on fishmeal and fish oil is a high priority for aquaculture in general, especially for example for salmonids that require high protein feed.

The aim of this project was to develop feed for salmonids based on microfungi grown on residual streams from the forest industry. The goal was to speed up the commercialisation, form new collaborations for strengthened international competitiveness for Swedish research and innovation concerning fungi-based fish feed.

Project outcome

Succesful production of meal based on single cell was achieved and feeding trials and showed good results. Life cyle assessment of a feed concept where soy meal is replaced by single cell meal showed environmental advantages. Main results are provided in the one pager below.
