Abstract : This study was designed to access some microalgae species to be used for aquaculture applications. Their nutritional value and productivity were tested. Also, used shrimp waste farms as a replaced low-cost medium. Isolated microalgae (Chlorella sp., Tetraselmis sp., Dunaliella salina, Navicula sp.1 and Navicula sp.2) by micropipette method from the Red sea water; were grown in f/2 and waste media at laboratory conditions (indoor) 22-23 oC, on a 24.00 light: dark cycle, at an irradiance of 3360 Lux. Cell number, cell volume, dry weight and biochemical composition (Lipid and Fatty acid) were estimated. Tetraselmis sp. showed the higher values in cell volume (388.65-728.43±3.7-11.5 µm3), dry weight per cell (242.03-325.35±35.3-5.4 ng), production per dry weight (61.28-71.86±9.1-5.9 ng d-1) and production per cell volume (99.47-157.84±3.8-9.4 µm3 d-1) more than other species tested in both experiments. Chlorella sp. (0.52-0.23±0.37-5.5 g) and Tetraselmis sp. (1.86-1.83±3.7-6.5 g) were the higher in MUFA and PUFA compare to other species in this study. Isolated microalgae species showed a good growth, lipid and fatty acid composition in a waste medium. The Saudi environmental conditions were good for microalgae to acclimate more lipid. Chlorella sp. and Tetraselmis sp. were recommended in this study for aquaculture applications as they present a good value in quality and quantity compare to other species tested. Used shrimp farms wastes to reduced medium cost and saved the environment.
