Abstract
Since large quantity of micro algae is needed for zooplankton as well as fish larval rearing system, the cultures need to be multiplied within the limited period of time. So mass culture needs to be done with suitable culture medium to meet sufficient requirement. The mass culture can be of batch culture, semi-continuous or continuous culture. A small inoculum equal to 0.5 % of the volume of the new culture will normally generate new healthy cultures for healthy cells of a robust species. However, if the species is delicate or the culture is less healthy, then a larger inoculum of 10% - 20% may be needed to support a new culture. The cultivation of microalgae required high consumption of water and on average needed 1000 L of water to produce a kilogram of biomass. The most common method of microalgae cultivation is to use an open cultivation system may be ponds, tanks, etc., or controlled cultivation systems after using various types of bioreactors. The cultivation process generally required acclimatized space with a stable temperature to encourage the activities that are necessary to the cell. Different cultivation modes also can be used for the rearing of microalgae; they may be phototrophic, heterotrophic, mixotrophic, and photoheterotrophic.
