Tetraselmis suecica is a marine green alga . It grows as single, motile cells visible under light microscope up to concentrations over one million cells per milliliter. It can be grown as a foodstock in aquaculture, being able to species such as rotifers of the genus Brachionus . It is a motile chlorophyte and contains a high lipid content.
Adarme-Vegas et al. (2014)  state that a reduction in biomass of Tetraselmis spp. was observed in high salinity cultures (50 ppt) and salinity cultures (5 and 10 ppt). Changes in salinity primarily altered bioimass productivity with cultures in 30 and 40 ppt having the highest growth rate and final productivity. Salinity had no effect on the percentage of EPA gold total Fatty Acid production.
