One of the most important sources of nutrition for the early life stages of marine larvae is the availability of microalgae from the species of Nannochloropsis aculata . This microalga is used as a main feed for rotifers, which are directly consumed by the larvae of two major marine finfish species that are farmed in the Lombok MADC, i.e Barramundi ( Lates carcarifer) and Silver Pompano (Trachinotus blochii) .
The study aims to find out the best management practices and the obstacles to the cultivation of Nannochloropsis aculata . Results were presented with a quantitative descriptive method with the data collection obtained from direct observation and literature reviews . In general, t he growth rate of this microalgae showed a great performance that finally it can be directly harvested by flowing it through to the larvae tanks in the hatchery.
