外文摘要：BACKGROUND Shrimp is one of the most popular marine foods consumed throughout the world and its freshness is a crucial indicator for consumers. However, the flesh quality degradation of shrimp during waterless live transport has been observed and the underlying mechanism remains unknown. RESULTS The present study aimed to clarify the biochemistry mechanisms of flesh degradation with integration of quality evaluation, metabolic profiling and histopathological analysis. The flesh quality indicators such as water holding capacity, protein and lipid contents, amino acid composition and myofiber components degraded with the prolongation of combined stress. In addition, the metabolites including gamma-aminobutyric acid, Val-Ala, Trh and derivatives of carnitine, phosphocholine and prostaglandin all reduced significantly under combined stress (P < 0.05). Furthermore, Kyoto Encyclopedia of Genes and Genomes () analysis revealed the enrichment of neuroactive ligand-receptor interaction and estrogen signaling pathways, indicating the involvement of neuroendocrine in stress response. Moreover, architecture impairment in hepatopancreas tissue verified the accumulation of metabolic disturbance. CONCLUSION Taken together, the findings of the present study indicate that neuroendocrine system mediates the flesh degradation of L. vannamei during waterless transport by disturbing the biochemical metabolic pathways and inducing architecture impairment of myofibril components.
