Short summary
This project aims to develop and validate sustainable fish feed ingredients based on protein concentrates derived from perennial grasses.
The project Land2Value-Interreg aims to develop and validate sustainable fish feed ingredients based on protein concentrates derived from perennial grasses. By applying advanced processing methods such as membrane filtration and fermentation, the project seeks to improve nutritional quality and reduce antinutritional factors (ANFs), enabling these ingredients to be used in fish feed for commercial aquaculture more efficiently. The overall goal is to develop efficient methods that increase the industrial readiness of these underutilized protein resources, strengthen resilience within the Interreg region, and reduce dependence on imported feed ingredients.
SLU’s Role
The department of Applied Animal Science and Welfare at SLU (THV) leads key activities in work package 3.2, related to fish feed development, analysis, and evaluation. The activities in this work package include nutritional and chemical analysis of protein concentrates, including quantification of antinutritional factors, development and optimization of fish feed formulations using extrusion and vacuum coating technologies, feeding trials on fish and sustainability analysis.
SLU (THV) will also provide support in connection with the land‑based aquaculture facility at Naturbruksskolan Sötåsen, including collaboration with industry and other stakeholders.
The activities are performed in close collaboration with Aarhus University (AU), Nordic/Baltic partners, and external expert competence (RISE).
Relevance and Impact
The project contributes to SLU’s strategic goals in sustainable food systems, circular bioeconomy, and environmentally responsible aquaculture. By upgrading agricultural side streams into high‑quality fish feed ingredients, the project supports climate mitigation, improved resource efficiency, and innovation in Swedish and European aquaculture.
