Summary: This study investigated the molecular responses of P. gravieri to salinity fluctuations. The results showed significant differences in gene expression between the hepatopancreas and gills of P. gravieri at different salinities, with ion transport-related genes mainly expressed in the gills. These findings contribute to our understanding of the salt tolerance mechanism in P. gravieri.

Summary: This study investigated the histological, physiological, and transcriptomic responses of C. fluminea to air exposure at different times. The results showed that air exposure caused changes in the histological structure and physiological function of the hepatopancreas, and influenced the expression of some key genes. These findings are important for the aquaculture and transportation of C. fluminea.

Summary: This study utilized RNA sequencing to analyze the transcriptomes of gill and hepatopancreas tissues of Macrobrachium nipponense under salinity stress, revealing the molecular mechanisms underlying salinity adaptation. Important salinity adaptation-related genes and signaling pathways, such as ion transport, oxidative phosphorylation, and glycometabolism, were found to be enriched.

Summary: Salinity is an important ecological factor that affects the physiology, survival, and distribution of crustaceans. The oriental river prawn, Macrobrachium nipponense, shows good growth performance in low salinity but is significantly affected by high salinity. Metabolic enzyme activity is significantly low at 7 and 14 ppt, indicating that these salinity levels are close to M. nipponense's iso-osmotic point. Through transcriptome and proteome analysis, several pathways related to salinity adaptation were enriched, and specific proteins and genes involved in these pathways were regulated in response to different salinity levels. The optimal survival salinity of M. nipponense may range from 0 ppt to 7 ppt.

Summary: The study found that short-term exposure to wastewater and ammonia-N did not affect the antioxidant defenses or digestive enzyme activity of mangrove crabs. However, histological changes indicated an increase in intracellular digestive activity in wastewater-exposed crabs.

Summary: This study identified differentially expressed miRNAs and target genes during salinity acclimation, which may play an important role in the regulation of bone metabolism. These genes or pathways could serve as key candidates for further studies on the molecular mechanism of teleost bone metabolism, and help with salinity acclimation and the development of marine culture of salmonid species.

Summary: Using histopathology, genomics, and transmission electron microscopy, the first symbiont profiles for Florida blue crabs (Callinectes sapidus) occupying freshwater to marine habitats were described. Twelve symbiont groups were identified, including ciliophorans, digenean, microsporidian, Haplosporidia, Hematodinium sp., Nematoda, filamentous bacteria, gregarine, Callinectes sapidus nudivirus, Octolasmis sp., Cambarincola sp., and putative microcell. Water temperature and salinity explained 48% of the variation in symbiont groups among Florida habitats, and salinity was positively correlated with C. sapidus symbiont diversity. Impaired crabs were more likely to host symbionts, and the microsporidian symbiont group had a particularly strong effect on C. sapidus reflex response. Considering full symbiont profiles and their associations with a spatially and temporally variable environment is important for assessing C. sapidus population health.

Summary: As the price of fishmeal rises, finding new protein sources to reduce fishmeal inclusion in aquafeeds is urgent. In this study, the effects of replacing fishmeal with a mixture of cottonseed protein concentrate (CPC) and Clostridium autoethanogenum protein (CAP) were evaluated. The results showed that the CPC and CAP mixture could replace 50% of dietary fishmeal without negative effects on rainbow trout.

Summary: This study investigated the enhanced removal of p-chloronitrobenzene (p-CNB) in high-salinity wastewater using 1.2 V low-voltage stimulation and halotolerant microorganisms. The results showed a significant increase in p-CNB removal rate in the electrostimulating microorganism reactor compared to the control group. The stimulation also enhanced the salt-in strategy and extracellular polymeric substances secretion in the microorganisms. Metagenomic and metatranscriptomic analysis revealed the enrichment of specific microorganism populations with p-CNB removal ability under voltage stimulation.

Summary: Low salinity has negative effects on reproduction in estuarine bivalves. It delays gametogenesis and spawning in oysters, except in June when low salinity promotes earlier gametogenesis. The findings suggest that low salinity not only affects the timing of reproduction but also extends the reproductive season.

Summary: This study focused on the behavioral and histopathological changes in striped catfish exposed to different salinity levels. The results showed significant alterations in behavior and histology of the gills, liver, and kidney at higher salinity conditions. Therefore, striped catfish can serve as a model bio-indicator in coastal aquaculture.

Summary: The effects of short-term low salinity stress on non-volatile flavor substances of Portunus trituberculatus were investigated. The results showed that low salinity stress significantly increased the level of bitter free amino acids in muscle and decreased the lactic acid content. In contrast, the umami free amino acid content in the hepatopancreas increased with lower salinity levels.
