Comprehensive analysis of transcriptomics and metabolomics to understand the flesh quality regulation of crucian carp (Carassius auratus) treated with short term micro-flowing water system

The short term micro-flowing purification system (STMFPS) has been shown to improve the flesh quality of freshwater fish. However, few studies have focused on involved underlying mechanisms. This study explored effect STMFPS market-size fish based combination metabolomics and transcriptomics methods. UPLC-QTOF/MS method was utilized screen metabolites predict possible major metabolic pathways during different treatment periods (0 d, 1 5 d 9 d). Furthermore, transcriptomic data demonstrated that differentially expressed genes detected in crucian carp muscle were 2915, 7852 7183 after treatment. Results showed TCA cycle, ornithine purine metabolism amino acid catabolism play important roles improving carp. may help understand mechanism aquatic products using STMFPS.
