Comparative Analysis on Main Nutrient Composition in Ukraine Scaled Carp Diploid and Triploid

[Objective] The water content,total ash,crude fat,crude protein,amino acid and fatty acid of the diploid and triploid Ukraine scaled carp were contrasted to supply the basic data for nutrition evaluation.[Method]The samples were collected from the back muscle of each carp,and the standard analysis methods were used.[Result] There was no difference in the content of water,total ash and crude fat in the muscle between diploid and triploid.The content of crude protein in triploid was significantly higher than those in diploid.The species of fatty acids,total fatty acid amount and the content of essential fatty acid in triploid were higher than those in diploid.There were 18 species amino acids in triploid and diploid.The content of flavour amino acids,essential amino acids,total amino acids and the amino acids score in triploid were higher than those in diploid.[Conclusion]The Ukraine scaled carp triploid has nutriology advantage compared with diploid.
