Abstract
- The sea cucumber Apostichopus japonicus is an economically important marine organism, and its aquaculture has rapidly developed in China. The very large market demand puts forward higher requirements for the economically efficient breeding of sea cucumbers. Sex and the associated reproductive processes have been reported to affect the physiological characteristics of sea cucumbers. However, little is known about the metabolism differences that related to sex and the associated reproductive processes and their potential effects on the efficiency of A. japonicus aquaculture. In this study, ultra-performance liquid chromatography was applied to investigate the variations in metabolic profiles in cell-free coelomic fluids (CCFs) of sea cucumbers of different sexes and reproductive states. A total of 4435 metabolites were detected, and the metabolic profiles of A. japonicus were significantly affected by both sexes and reproductive process. The differentially abundant metabolites in CCFs of A. japonicus of different sexes and reproductive states were also screened and analyzed. The findings revealed that unsaturated fatty acid synthesis and phenylalanine metabolism were the most significantly changed pathways. Moreover, the weakest ability to synthesize capsaicin using phenylalanine was found in A. japonicus after spawning. Our study provides new insights into the metabolic response of A. japonicus during the reproductive process, and also provides valuable references for the economically efficient breeding of A. japonicus.
