In order to analyze the nutrition characteristics of different kinds of roes, we determined the proximate composition,amino acids, fatty acids and mineral elements of roes of Salmon solar, Exocoetidae cypselurus, Pseudosciaena crocea, Acipenser baeri, A. gueldenstaedti, A. schrenckii and Huso dauricus. The results show that E. cypselurus roe had the highest moisture content(813.1 g·kg~(–1)), lowest ash content(16.0 g·kg~(–1)) and lowest crude protein content(133.5 g·kg~(–1)). A. schrenckii roe had the highest crude protein content(281.5 g·kg~(–1)) and crude fat content(166.3 g·kg~(–1)), and S. solar roe have the lowest crude fat content(54.9 g·kg~(–1)).The contents of total amino acids(27.67%) and delicious amino acids(9.31%) in A. gueldenstaedti roe were the highest. The amino acid score(AAS) of the seven kinds of roes were higher than the FAO/WTO standard except tryptophan, and the ratio of essential amino acids to total amino acids ranged from 41.34% to 43.89%. The contents of saturated fatty acids(SFA), m
