The use of low-trophic marine resources (like macroalgae, mussels and algae-eating fish) and mesopelagic organisms. This project will help generate basic knowledge needed to utilise such novel marine resources as food or feed in a sustainable way.

The use of low-trophic marine resources (like macroalgae, mussels and algae-eating fish) and other less harvested marine resources like mesopelagic organisms, either directly as food or as a feed ingredient in aquaculture, needs further development to become a larger contributor towards food production.

The main aim of the project is to assess nutritional quality and -safety of novel marine resources as well as assessing the sustainability and ecosystem effects of an increased production and harvest of these species. A profiling of nutrients and undesirable substances in these raw materials will be performed and we will asses the suitability and risks of these marine resources to be used as either food or feed. We will also perform a sustainability assessment of utilizing new marine resources from low trophic levels.

The project is structured through seven work packages (WP) with their respective work package leaders and the aim is to gain knowledge on the whole production chain of these novel marine resources, from ocean to oven.

Description of work packages

WP1: Profiling of nutrients and undesirables in novel marine resources

Objective: Explore the nutrients and contaminants associated with marine low-trophic and mesopelagic resources (macroalgae, mussels, mesopelagic fish, polychaetas). Suitability for direct human consumption as well as for use in fish feeds will be evaluated in close collaboration with WP2, 3 and 4. (WP leader: Martin Wiech)

WP2: Risk assessment of challenges for food or feed safety

Objective: Undertake a feed and food safety assessment of potential hazards (identified in WP1) found in novel marine resources or raw materials derived from them. The guidelines for risk assessment for feed and animal health made by European Food Safety Authority’s (EFSA) will be used. (WP leader: Marc Berntssen)

WP3: Suitability of novel marine ingredients in Atlantic salmon feeds

Objective: The possibilities of using feed ingredients from organisms low in the marine trophic levels (e.g. macroalgae, blue mussel) and from mesopelagic fish in Atlantic salmon feeds will be explored. Nutritional qualities and -challenges with these less known ingredients must be better understood, they will therefore be assessed for their effects on growth and health of the fish. (WP leader: Sofie Remø)

WP4: Assessment of novel marine resources for human consumption 

Objective: The aim here is to evaluate the potential of novel marine resources to supply nutrients, and their potential risks as sources of undesirable substances (e.g. heavy metals, wax esters) when used for direct human consumption. Rodent models will be used to gain knowledge on this area. (WP leader: Lise Madsen)

WP5: Ecosystem impact assessment of large-scale farming of low-trophic organisms

Objective: Large-scale farming of low-trophic species can compromise the functioning of marine ecosystems by influencing the transfer of nutrients and energy in marine food chains, and consequently the biochemical and nutritional content of the product. Therefore, the biomass production of hypothetical low-trophic aquaculture scenarios will be modelled to study effects on coastal ecosystem ecology attributed to extraction of their trophic resources. (WP leader: Tore Strohmeier)

WP6: Sustainability and circular economy 

Objective: For aquaculture to grow in a sustainable way, finding new feed resources with a lower environmental footprint is pivotal. This might be achieved by sourcing feed ingredients from large-scale farming of low-trophic species (like mussels, seaweed) or from resources with large underutilized volumes (like mesopelagic fish). Through life cycle analysis, we aim to study the potential environmental impact of integrating such novel marine resources into Norwegian salmon farming. (WP leader: Erik-Jan Lock)

WP7: Project monitoring, communication and dissemination

Objective: Dissemination of knowledge generated in the project to regulatory bodies, policy makers, industry and the general public for effective knowledge transfer and action through science. (WP leader: Antony Prabhu)
