Abstract :

     In order to examine and determine the best and the most effective diet for Artemia, Artemia Franciscana was fed under laboratory conditions using three sources of diet: T1: rice bran concentrate enriched with yeast, T2: Nannochloropsis oculata, T3: the combination of rice bran concentrate enriched with yeast and Nannochloropsis oculata in three treatments and three replications for 14 days. The results of the three treatments were compared. At the end of the period, in the third treatment by removing 1962 grams of Artemia biomass and survival rates of 85/71%, the best condition was observed. There was significant difference between treatments one and two, with the biomass of 1778 g and 1621 g, and survival rates of 78/18% and 71/82%, respectively and treatment three dietary by the combination of rice bran concentrate enriched with yeast and Nannochloropsis algae. According to the results obtained it can be proved that the diet resulted from agricultural waste coupled with adequate amounts of from single-cell algae and yeast will suffice to increase production of Artemia biomass and reduce costs associated with building diets for rearing Artemia and its use for aquaculture, and there is no need for costly mass production of single cell algae.
