“…WHC of T4 at the end of storage duration (31.9 ± 7.8%) is the highest which con rms the result of the highest protein content of T4. Similar observations had been carried out for Litopenaeus vannamei during ice storage which is explained initial increase by the fact that protein in muscle oxidizes before the lipids lead to move water from myo brils into extracellular spaces resulted enhances of WHC (Mehta et al 2021). pH changes during 60 days of storage are probably due to the formation of TVB-N developed from microbial activity and leads to the formation of non-protein formation compounds (Gonçalves and Lira Santos 2019).…”

Effects of two probiotics, Bacillus subtilis (ATCC 6633) and Lactobacillus plantarum (RITCC 1273) on the Litopenaeus vannamei postlarvae were investigated. Bacillus (B1)106 and (B2) 3×106 CFU.L− 1 and Lactobacillus (L1) 105 and (L2) 3×105 CFU.L− 1) were added to water in 5 treatments of different combinations of B1, B2, L1, and L2 to determine water quality, Hemolymph indices, salinity stress, growth rate, and productive parameters. after that, shrimps were transferred to seafood processing and quality control lab to evaluate shelf-life and quality change during freezing preservation at -18℃ for 90 days. Nutritional values, pH, Thiobarbituric acid reactive substances (TBARS), Total volatile nitrogen determination (TVB-N), Water holding capacity (WHC), drip loss, and texture profile were evaluated. According to the results, water quality remained almost the same during the aquaculture phase of the experiment and no significant changes were observed in the pH, ammonia nitrogen, nitrate-nitrogen, and nitrite-nitrogen of water. Growth performance tests indicated that T1 (105 L*3×106 B CFU.L− 1) had the highest weight gain (WG), survival rate (SR), specific growth rate (SGR), and relative feed conversion efficacy (RFC). T4 (3×105 L*106 B CFU.L− 1) indicated lowest triglyceride (274.51 ± 17 mg/dL) and highest cholesterol level (3581.61 ± 1222 mg/dL) significantly. Storage of shrimps demonstrated that the best performance belongs to T4 which had the highest WHC (31.9 ± 7.8%) and lowest drip loss (4.7 ± 0.4%) among treatments at day 60. Overall, our results showed interaction of B. subtilis and L. Plantarum significantly improves shrimp's growth rate, and helps to improve some of the chemical characteristics during storage at -18℃.

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 (https://www.genome.jp/kegg) 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. © 2022 Society of Chemical Industry.

The flesh quality degradation of shrimp during waterless transport has been observed and the underlying mechanism remains unknown. 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 characteristics 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, KEGG analysis discovered 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. Altogether, these findings indicate that neuroendocrine system mediates the flesh degradation of L. vannamei during waterless transport by disturbing the biochemical metabolic pathways and inducing architecture impairment on myofibril fibers.
