Isochrysis galbana is a species of haptophytes. It is the species species of the genus Isochrysis . It is an outstanding food for various bivalve larvae. and is now widely cultured for use in the bivalve aquaculture industry.  This unicellular is investigated for its high amount of Fucoxanthin (18.23 mg / g dried sample).  The Isochrysis galbana extract is said to have some cosmetic and hair-growth properties when using hexane , ethyl acetate , ethanol , water , methanol , goldisopropanol as extractants . 
Isochrysis also best food for the 1st stage of P. monodon protozoea larvae stage.
