Abstract:The study were conducted to evaluate the commercial potential of Centropages mcmurrichi as aquatic food resources after a comprehensive analysis of its basic nutritional constituents, part of the minerals, Amino acid compositions and various fatty acid components of lipids via modern research methods of biochemistry . The determination results indicated that Centropages mcmurrichi（dry weight） contained a high level of crude protein（64.64%） as well as abundant minerals which consisted of Fe（339.28 mg/kg）, Zn（97.91 mg/kg） and Ca（3316.47mg/kg） respectively. In addition, it was not richer in the average percentage of fatty acid composition or the content of total sugar when compared with other marine copepods like Acartia clausi. The essential amino acids index（EAAI） was 80.51.Thirty-nine point fifty five percent of the total fifteen types of amino acids comprised of essential amino acids of which Leucine, Lysine and Valine were the most prevalent, and 60.45% were non-essential amino acids, Glutamic acid, Asparagine and Alanine. And Centropages mcmurrichi had special seafood flavor because of the five delicious amino acids in which glutaminic acid（7.65%） and aspartic acid（5.81%） made up a higher percentage. Fatty acid profiles of Centropages mcmurrichi showed that 40.65% saturated fatty acid, 16.05% monounsaturated and 42.09% polyunsaturated fatty acids occupied the total fatty acids, respectively. Among this detected eighteen diffident types of fatty acids, docosahexaenoic acid（DHA；22：6n-3） and eicosapentaenoic acid（EPA；20：5n-3） were the predominant fatty acids of Centropages mcmurrichi, which constituted 27.32% of total fatty acids. Therefore, Centropages mcmurrichi were esploitable as one of the high-quality marine aquatic resources.
