study on fatty acid combination of giant sturgeon (huso huso) juveniles carca which fed different levels of gingar (zingiber officinale)

the aim of this study was to evaluate the biochemic combination of giant sturgeon (huso huso) juveniles carcass which fed with gingar (zingiber officinale) extract. fish with average initial weight 15 + 0.8 g fed 0.5% and 1%  of gingar hydroalcohol extract for 8 weeks. samples were gathered in the final of experimental period and the fatty acids were determined by gas chromatography. results show that there were no  significant differences between saturated fatty acids (∑ sfa) amounts of gingar treatment and control  (p>0.05) but there were significant difference between them in ∑ mufa content (p<0.05) and the most was observed in the treatment which fed 1 % gingar. the most amount of pufa was observed in the treatment which fed 0.5 % gingar. the most relation of w-3 / w-6 was observed from the 0.5% treatment but with no significant difference with control (p>0.05). the most index of pufa/sfa was observed in the treatment which fed 0.5% gingar (p<0.05). in conclusion, the nutrition performance was approved in treatments which fed gingar, so the dietary gingar supplement determined beneficent for fatty acids nutritional value and organic aquaculture of  giant sturgeon and consumes health too.
