The red drum (Sciaenops ocellatus), a globally significant marine aquaculture species, boasts formidable osmoregulatory capabilities and remarkable adaptability to low salinity, making it an ideal candidate for commercial cultivation in inland low salinity saline-alkaline waters. However, studies on the fundamental nutritional composition and flavor quality of S. ocellatus in these inland low salinity saline-alkaline waters remain unreported. This study delves into the impact of inland low salinity saline-alkaline environments on the basic nutritional components and nonvolatile flavor substances (including free amino acids and free nucleotides) in the muscle tissue of S. ocellatus. The findings reveal that redfish cultivated in these conditions exhibit a significant increase in the crude fat, ash, and protein content in their dorsal muscle tissue, coupled with a decrease in moisture content (p < 0.05), indicating an enhancement in the nutritional value of the dorsal muscle tissue. Furthermore, this cultivation environment significantly elevates the content of free amino acids in the muscle tissue (p < 0.05), particularly those contributing to umami and sweet tastes, while reducing the relative content of bitter amino acids. Although the total content of free nucleotides decreased, the equivalent umami concentration (EUC) in the muscle tissue markedly increased (p < 0.05) due to the synergistic effect of umami amino acids and flavor nucleotides, enhancing the umami taste characteristics. Therefore, inland low salinity saline-alkaline aquaculture not only elevates the nutritional value of S. ocellatus muscle tissue but also improves its umami flavor characteristics. This discovery opens new perspectives for further research into the impact of inland low salinity saline-alkaline environments on the flavor properties of marine animals.

“…Metabolites are involved in regulating the immune response or signal pathways of the hosts challenged by pathogens or external stresses (24)(25)(26). For example, the liver metabolome of yellow catfish showed that iron metabolism modulated by hepcidin could contribute to the defense against Aeromonas veronii infection (24).…”

“…For example, the liver metabolome of yellow catfish showed that iron metabolism modulated by hepcidin could contribute to the defense against Aeromonas veronii infection (24). The metabolomic analysis of the gill in Oreochromis mossambicus found that the levels of amino acids, osmolytes, and energy substances are significantly affected by osmotic stresses (25). The spleen metabolome of Paralichthys olivaceus identified numerous metabolites responding to Edwardsiella tarda invasion and temperature alteration, including L-methionine and UDP-glucose (26).…”

IntroductionAeromonas hydrophila, a bacterium widely distributed in the natural environment, causes multiple diseases in various animals. Exploring the mechanism of the host defense against A. hydrophila can help develop efficient strategies against Aeromonas infection.MethodsHerein, we investigated the temporal influence of A. hydrophila on the Chinese soft-shelled turtle, an economically important species, at the biochemical, transcriptomic, and metabolomic levels. Plasma parameters were detected with the test kits. Transcriptome and metabolome were respectively applied to screen the differentially expressed genes and metabolites.ResultsThe contents or activities of these plasma parameters were significantly increased at 24 hpi and declined at 96 hpi, indicating that 24 and 96 hpi were two important time points during infection. Totals of 3121 and 274 differentially expressed genes (DEGs) from the transcriptome while 74 and 91 differentially abundant metabolites (DAMs) from the metabolome were detected at 24 and 96 hpi. The top DEGs at 24 hpi included Ccl2, Ccl3, Ccl4, Il1β, Il6, Il7, Il15, Tnf, and Tnfr1 while Zap70, Cd3g, Cd8a, Itk, Pik3r3, Cd247, Malt1, and Cd4 were the most abundant at 96 hpi. The predominant DAMs included O-phospho-L-serine, γ-Aminobutyric acid, orotate, L-tyrosine, and L-tryptophan at 24 hpi, as well as L-glutamic acid, L-arginine, glutathione, glutathione disulfide, and citric acid at 96 hpi.DiscussionThe combined analysis of DEGs and DAMs revealed that tryptophan metabolism, nicotinate and nicotinamide metabolism, as well as starch and sucrose metabolism, were the most important signaling pathways at the early infective stage while tyrosine metabolism, pyrimidine metabolism, as well as alanine, aspartate and glutamate metabolism were the most crucial pathways at the later stage. In general, our results indicated that the Chinese soft-shelled turtle displays stage-specific physiological responses to resist A. hydrophila infection.

“…Because of salinity intrusion, a huge threat has been imposed on the existing biodiversity in coastal areas. Environmental salinity is a crucial factor affecting aquatic organism persistence and physiological processes (Alam et al, 2020: Su et al, 2023. Every aquatic organism has several limiting factors that influence its abundance in aquatic media, and salinity is one of them.…”

Salinity intrusion is one of the major climate-caused problems globally. The present work evaluated the impacts of salinity on the gonadal improvement in striped catfish (Pangasianodon hypophthalmus). The fingerlings of striped catfish (8.63 g) were cultured at three different salinity levels (0, 4, and 8 ppt) for two years. Gonadal development was assessed by gonadosomatic index (GSI) and histological analysis over six months at the end of two years of rearing from April to September. The gonad histological observations and the associated changes in GSI showed that the male and female striped catfish cultured in different salinity conditions could complete testicular and ovarian maturation at 4 and 8 ppt salinity by June and July, as they have grown at 0 ppt salinity. The current findings indicate that despite a slow rate of development, salinity up to 8 ppt showed a positive impact on the gonadal development of striped catfish. Asian J. Med. Biol.
