Habitat
Marine / brackish water

Tetraselmis suecica is a marine green microalga, single-celled and flagellate, with four flagella and an ovoid cell covered by a theca. It is one of the reference microalgae as live feed in aquaculture thanks to its high protein and lipid content, good digestibility and robustness in cultivation.

Characteristics

  • Ovoid green cell with four flagella.
  • High protein and lipid content.
  • Good digestibility as live feed.
  • Robust and fast-growing in marine medium.

Cultivation

It is grown in marine or brackish medium, both in photobioreactors and ponds, and is common in aquaculture hatcheries. Its robustness eases production at scale.

Applications

Live feed in aquaculture (larvae, molluscs)Animal feedBiomass and proteinBiofuels (under study)

FAQ

Mainly as live feed in aquaculture: it feeds and enriches fish and mollusc larvae thanks to its high nutritional value and good digestibility.
