Customized FPA cultivation technology for fish breeding farms

Subitec offers scalable systems from small to large scale on-site production of microalgae in closed and fully automated systems.

Producing fish sustainably at acceptable cost and ensuring biosecurity and quality continues to be the day-to-day challenge that the fish farming industry has to deal with. Several studies have shown that the direct or indirect use of microalgae as feed has positively impacted the growth rate, the survival rate and the nutritional quality of fish. Microalgae are an indispensable feed source with high nutritional value and transfer of nutrients through whole food chains. The nutritional properties of microalgae including protein, selected carotenoids, lipids and fatty acids, are essential in the rearing of all stages of breeding in aquaculture.

On-site cultivation and application of live microalgae for early stage feed is increasing in the industry. To solve the predominant issues in cultivation of microalgae and to ensure safe and stable on-site production of microalgae, Subitec has developed a closed, fully automatic cultivation system for the production of microalgae that is used as feed for e.g. copepods and rotifers for fish larvae, shrimp and shellfish larvae.
