Summary: In this study, the osmoregulatory response of large yellow croaker to low water salinity was investigated. The survival rate of large yellow croaker was stable within a specific salinity range, and the NKA activity in the kidney and gill was regulated by salinity variations. Furthermore, the expression of PRLR, NHE beta, and NCC genes were also associated with salinity changes.

Summary: Life in freshwater poses osmotic and energetic challenges for organisms, particularly arthropods. The mechanisms of ion uptake from freshwater environments are still poorly understood, but the proton pump V-type H+ ATPase (VHA) and the Na+/H+ antiporter (NHA) have been proposed as potential models. This study explores the evidence for these models in crustaceans, insects, and teleost fish and emphasizes the need for further research on ion uptake mechanisms in freshwater habitats.

Summary: In this study, the intestinal microbiota of juvenile striped catfish exposed to a salinity gradient was investigated. It was found that the diversity of the intestinal microbiota decreased with increasing salinity, and certain microbial genera were affected differently. Furthermore, the expression of certain genes associated with osmoregulation and stress responses was modified in the fish intestine. These findings indicate that the intestinal microbiota and gene expression play important roles in the adaptation of fish to hyperosmotic environments.

Summary: By manipulating salt and water balance in goldfish, the ghrelinergic system activity can be modulated to enhance ion acquisition. Goldfish respond to disruptions in salt and water balance by increasing NKA activity and modulating mRNA expression to adapt to environmental changes.

Summary: The study revealed that the freshwater crab Pagei survives in fresh water by maintaining cellular isosmoticity, while the shrimp Jelskii exhibits clear hypo-osmoregulatory ability. Each of the two species has evolved distinct transcriptional and systemic strategies to adapt to the freshwater environment.

Summary: Prolonged drought and freshwater diversion are leading to more common periods of hypersalinity in coastal ecosystems, affecting the tolerance of endemic species such as the red drum. This study found significant impacts on plasma osmolality and muscle water in red drum exposed to hypersalinity, but adaptation led to changes in gill and intestinal plasticity to cope with the challenging conditions.

Summary: ATP1A3 encodes the alpha 3 isoform of Na,K-ATPase and is expressed only in neurons. Mutations in this gene result in a variety of phenotypes, with specific syndromes associated with unique substitutions. The pathogenicity of the R756H mutation was tested in mammalian cells and found to have reduced turnover rate, altered ion affinity, and resistance to misfolding.

Summary: The fat greenling species Hexagrammos otakii is being evaluated for aquaculture production in RAS systems. A study on the effects of salinity on survival, growth, blood parameters, gill structure, and gene expression in H. otakii revealed that low salinity can impact fish health and growth, causing changes in blood parameters and gill structure. Overall, maintaining salinities between 12-29 PSU is optimal for commercial aquaculture production of juvenile H. otakii.

Summary: The study found that the specific ion effects of Na+ and K+ were different on the growth of Ulva lactuca. Ulva lactuca showed better growth with high concentrations of NaCl, while KCl might have adverse effects on photosynthesis and cell wall. Transcription of PM H+-ATPase was induced specifically by high concentrations of Na+, while the induction of PM-Na+/K+-ATPase-like alone could not improve the growth of KCl-treated Ulva lactuca.

Summary: The study on the kidney function of European sea bass in high salinity conditions revealed slight differences in response to high salinity between the two genetic lineages, with Mediterranean sea bass showing high blood osmolality in hypersaline water but not showing improved overall response compared to the Atlantic lineage. At the kidney level, the traits analyzed differ slightly between genetic lineages, potentially as a response to high blood osmolalities in Mediterranean sea bass.

Summary: Temperature and salinity can impact the physiological responses of aquaculture species. European sea bass and milkfish, farmed in Europe and Southeast Asia respectively, showed increased hepatic antioxidant enzyme activity in response to temperature challenges combined with hypo-osmotic stress over a four-week period. Despite differences in expression profiles, both species exhibited enhanced antioxidant responses under the conditions of the study.

Summary: In the study on European sea bass, it was found that freshwater intolerant fish exhibited significant changes in telomere dynamics, including attrition and decreased mRNA expression of tert, after freshwater exposure. On the other hand, freshwater tolerant fish did not show significant modifications in telomere dynamics. This suggests that telomere dynamics can serve as an integrative marker to study environmental stress in fish, while taking into consideration individual phenotypic plasticity in response to freshwater exposure.

Summary: Estrogens, such as E2 and EE2, pose a global threat to aquatic ecosystems due to their pseudo-persistence, high estrogenic activity, and toxicity towards non-target species. This study investigated the lethal effects of estrogens on the marine calanoid copepod A. clausi, finding stage-specific responses to E2 and EE2 exposure, with embryos being the most vulnerable and adults showing the lowest sensitivity to acute estrogen exposure. Embryos showed non-monotonic dose-response to low realistic concentrations of E2 and EE2. Fitness of the females of the generation F0 was negatively impacted at higher concentrations of EE2, but A. clausi showed tolerance to environmentally relevant concentrations.

The results showed significant differences in gene expression between genetic lineages, which may contribute to different responses to osmotic stress in D. labrax lineages.

Summary: The pituitary is an important endocrine gland in all vertebrates, playing a role in both organismal homeostasis and physiological adaptation. It coordinates sexual maturation by producing and releasing hormones that stimulate gonad development. A study was conducted on the developmental dynamics of the pituitary in the model fish medaka (Oryzias latipes), where 68 female fish were sampled for their pituitary and ovaries. Histological examination of the ovaries and RNA-seq analysis of the pituitary glands were performed to determine the timing of hormone production priorities and provide a comprehensive resource for their regulation.

Summary: This study found that early exposure to (xeno)estrogens can increase the expression of skeleton-associated genes in fish, but only natural estrogen E2 leads to increased mineralization. This suggests that the effects of (xeno)estrogens on early skeletal development in fish may vary.

Summary: MicroRNAs (miRNAs) have been identified as a new category of biomarkers that can be used for sex identification and acute stress characterization in fish. Through small RNA-sequencing analysis and RT-qPCR validation, multiple miRNAs were found to be differentially expressed between sexes and during acute stress in European seabass. This study provides new insights and recommendations for the use of miRNAs as biomarkers in European seabass and potentially other fish species.

Summary: Epigenetic modifications, specifically DNA methylation, play a significant role in generating phenotypic diversity in fish and driving adaptive evolutionary processes. However, the impact of salinity on whole-genome DNA methylation in euryhaline marine species that migrate between salinity-contrasted habitats has not been well-studied. This research investigates the role of salinity-induced DNA methylation in fish, with a focus on the gill as an important organ involved in environmental adaptation.
