Improves the fish health

The feed has been developed to look like the fish' natural feed, which contains some 70-80 % freshwater (dryfeed contains around 11-12 % water).

The pellets used in the aquaculture business today are hard to ensure that they can be transported and blown out into the enclosures using highly pressurized air, and are therefore not made with the fish' wellbeing in mind.

The wetfeed has a positive effect on the fish' digestion of fat and protein (see picture), something that has an effect on growth. This is documented in cod and trout, but research has also been done indicating a similar effect on salmon.

Prevents plastic leaking into nature


The technology is primarily developed to improve feed intake and better the digestability through adding water to the feed. The point in this regard however is, that regular feed can be transported through water instead of using air pressure.

The system enables you to choose whether you want to transform dryfeed into wetfeed or just transport dry pellets through water. It is more efficient to transport feed through water than using air pressure, and the wear and tear on feedlines is eliminated. Water-transported feed does not lead to wear and tear on the tubes, unlike the dryfeed. 

A study made by the Norwegian society for the conservation of nature has shown that Norwegian breeding facilities spread large quantities of microplastics into the sea. A rough estimate shows a spread of potentially 325 tonnes of microplastics fra plastic tubes used in fish feeding.

These emissions arise when pellets are blown through the feeding tubes at high speeds. On the way they scrape the inside of the pipes and create scratches, loosening and leading microplastic into the sea. 

Environmental organisations believe the aquaculture sector has to implement new technology quickly. (further reading).




No CO2 emissions. Reduced energy consumption and cost


The feeding system of SeaFarm Solutions need minimal energy to operate. It feeds 2-3 tonnes per hour per enclosure, with an energy consumption of 1 kW/h per enclosure. If this is compared to the energy consumption used in the aquaculture industry today, our system will give a reduced energy consumption for the facilities of about 95 %.

Todays renewable technology (wind/solar and battery packs) combined with SeaFarm Solutions' feeding facility, a feed-fleet can operate without a diesel generator and without receiving power from land.

The same facility can be used without a loop, almost without changes, to transport regular feed through water instead of using highly pressurized air. The energy consumption in such a facility will be reduced to 0,75 kW/h per enclosure.

There are over 1000 breeding facilities in Norway today, using over 100 million liters of diesel each year. A report made by DNV GL (august 2018) shows that 80 % of the production can be electrified on commercial terms. This will reduce yearly CO2 emissions by 230 000 tonnes, while at the same time reducing noise and diesel spillage by the facilities. The report concludes that changing from a diesel generator to landbased power is both cost efficient and environmental.

SeaFarm Solutions has completed the development of a feeding technology preventing plastic leaking into nature.

Prevents feed-spills in nature

1 620 000 000 kg of fish feed was produced in Norway in 2016. Of this an estimated 1 % was lost in dust and crumbs. This feed never reaches the fish. This means that 16 200 000 kg of feed was not utilized. This affects not only the environment, men also the profitability of the business (Salmar). 

SeaFarm Solutions can reduce this to almost 0, by retrieving crushed feed on the edge of the enclosure/feed-fleet and keeping it in the loop.
