Nannochloropsis sp. is one of the most extensively used microalgae in aquaculture. It is a marine microalga (size 2-4 µm) selected for its high content of ω-3 poly-unsaturated fatty acids, especially eicosapentaenoic acid (EPA). Nannochloropsis is also a rich source of pigments such as β- carotene, violaxanthin and zeaxanthin. The overall high carotenoid content combined with elevated levels of polyphenols and α-tocopherols provides Nannochloropsis with high antioxidant capacities.
Nannochloropsis are the algae of choice for cultivation and EPA pre-enrichment of rotifers.
Nannochloropsis is recommended in fin fish larviculture as a Green Water Treatment. Due to its small size single cells exhibit excellent buoyancy and remain in the water column for very long periods. Use of Nannochloropsis exerts a positive effect on bacterial communities in larval rearing tanks and significantly improves the overall health and survival rate.
