Nannochloropsis gaditana

About the algae:

Nannochloropsis is an algal genus of which six individual species of algae are known. The individual species are found mainly in salt water, but occasionally also in brackish or fresh water. For industrial applications, Nannochloropsis algae are of particular interest due to their rapid growth, their high lipid content and high content of polyunsaturated fatty acids such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Since Nannochloropsis are at the basis of the aquatic food chain, they provide an immense primary entry of these high-quality omega-3 fatty acids for organisms higher up the food chain. This property makes Nannochloropsis a suitable aquaculture feed. Additionally, due to their ability to accumulate high lipid levels from 18% up to 47.5% per dry weight, Nannochloropsis are becoming more and more interesting for the biofuel industry.

 

About the product:

The most common use of Nannochloropsis algae is as Rotifera feed in aquaculture systems. Here, the algae are mostly used as a living culture to reproduce the natural aquatic food chain in an aquaculture system and to ensure both the supply of valuable ingredients and positive effects on animal health. Especially the supply of EPA and DHA is essential for the survival and growth of fish larvae. Nannochloropsis algae are also an alternative protein source to fishmeal, making them promising candidates in new sustainable aquaculture systems. Furthermore, due to their high omega-3 fatty acid content, they are gaining more and more attention as a dietary supplement for humans.
