AG Fisk Workshop

Increased sustainability in aquaculture with focus on feed and side streams

Workshop held in Grand Hotel Reykjavik, 11th of October

Supported by Nordic Council of Ministers – Working Group for Fisheries (AG-Fisk)

Aquaculture is becoming an important pillar in Nordic economy, especially in Norway, Faroe Islands, and Iceland. Development is fast in the industry, with many challenges and opportunities. At the workshop held in Grand Hotel 11th of October, two important issues will be addressed: feed production for salmonids and processing of side-streams from fish farming and processing. 

Side-streams from salmon farming, generated in large quantities, are often not of high enough quality to be used in the production of valuable products. The volumes generated during production and processing are high and contain large amounts of water and do quickly get damaged. With increasing aquaculture including land-based production, the importance of finding ways to utilize aquaculture side streams are increasing including side-streams from slaughtering, Sludge and Side-streams from K2 (self-dead fish).

One of the main limiting factors in salmon farming is the lack of availability of raw materials for feed production. It is also an important environmental matter, with around 60% of the carbon footprint in salmon production, comes from the feed. Future feed production for fish farming will be the most important challenge for the industry.

The purpose of the workshop will be strengthening collaboration between research and industry in the Nordic countries with the overall aim of reaching sustainable utilization of marine resources and production of high-quality products, and thus strengthening the Nordic marine bioeconomy

• Draw a picture of how things are going in feed production and processing of side-streams in the salmon production

Exploration of upcoming and potential sustainable, local alternative protein sources for inclusion in Nordic aquaculture feed

• Optimisation of collection, extraction, and separation methods of the ingredients with the aim of using them for further high-quality product development and utilization for both human and animal consumption.

• Provide an overview of best practises in the handling of side streams generated within aquaculture to increase their overall value.

The conference/workshop is expected to bring Nordic companies and researchers together on the aspects of novel/alternative feed ingredients and utilisation of side streams from aquaculture. The topics discussed at the event will furthermore summarize and add knowledge in the following areas:

• Detailed mapping of the aquaculture side streams, both quantity as well as composition.

• Understanding of upcoming and most developed alternative/novel ingredients, which knowledge gaps exist (including nutritional, digestibility, feed formulation etc) and how they can be fast tracked to market

• Current use and markets

• Optimized treatment during the collection and storage of different side streams categories

• Improved knowledge on extraction and purification methods to obtain higher quality ingredients from different aquaculture side streams.

• Detailed information on storage stability, safety and quality of the developed ingredients and products

• Logistics
