Abstract	This work aims at culturing different Chlorella species, monitoring growth and estimating the nutritional quality for further application of complete cells and lipid extracted biomass in Artemia franciscana feeding. We conducted experiments using C. marina, C. salina, C. capsulata, C. stigmatophora and C. vulgaris that were batch cultured for 14 days. C. salina showed the maximal count on the sixth day while C. marina recorded the maximum growth rate (2 ± 0.177). However, C. capsulata and C. stigmatophora recorded the minimum rate (1.5 ± 0.11). Analyses of algal biomass showed that C. capsulata contains maximal lipids and carbohydrates, but the minimal protein (22.8 ± 1.4 %). However, C. salina contained the highest protein (33.1 ± 1.4 %). After oil extraction, there were no significant losses in the other biochemical constituents of the studied Chlorella species. Considering algae metabolites, saturated fatty acids were the main constituent in the fatty acids methyl esters (FAMEs). Palmitic and stearic acids were dominant. Amino acid pools of the experimental marine Chlorella species were found to contain lysine, methionine and histidine; but were deficient in cysteine. The present investigation showed that lipids, proteins and protein to lipid ratio of A. franciscana napulli enriched with mixed cells of Chlorella species were enhanced by (22 %); 1.96 and 1.33 folds, respectively. Furthermore, the growth and survival of A. franciscana showed significant increases when fed on lipid extracted algae residuals, especially that of a mixed diet; which is considered as an important achievement and confirms that the residual algae biomass can be significantly used for aquaculture feeding.
