High mortality frequently occurs in larval mass production of Persian sturgeon fish, Acipenser persicus. Nutritional deficiencies in live food, Artemia urmiana nauplii, fed to larvae could be a reason. A series of experiments was carried out to evaluate the effects of nutritional enrichment of Artemia by oils in different concentrations with or without different levels of vitamin C during two enrichment periods (12 and 24h) on survival, growth rate and salinity tolerance in Persian sturgeon larvae reared in tanks after 20 days. Four types of oils (ICES30/4, sturgeon ovary, cod liver, and linseed oils) were evaluated. HUFA oil source with or without vitamin C did not affect the growth rate of Persian sturgeon larvae. Nevertheless, survival rates and chemical compositions were significantly improved (P
