Abstract
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<0.05) only in fish larvae fed Artemia enriched HUFA oil supplemented with vitamin C. ICES30/4 was the best oil source for improving the chemical composition including fatty acids in Persian sturgeon larvae only when it was supplemented with vitamin C. Lower levels of vitamin C (less than 30%) and longer enrichment period (24h) were more effective (P<0.05) in improving on chemical composition of sturgeon fish larvae. When the sturgeon larvae were exposed to salinity test, those fed with HUFA enriched Artemia showed tolerance only up to 6 ppt while those fed HUFA+vitamin C enriched Artemia demonstrated high tolerance (≥ 90% survival) up to 12 ppt for 120h. Although the enrichment of Artemia urmiana with 300 ppm ICES30/4 and 30% vitamin C gave the best salinity tolerance at 12ppt (100% survival), the enrichment with 300 ppm sturgeon ovary oil and 10% vitamin C was economically affective in increasing the salinity tolerance of Persian sturgeon larvae (98 % survival).
