Bivalve mollusks frequently experience salinity fluctuations that may drive oxidative stress (OS) in the organism. Here we investigated OS markers and histopathological changes gills hemolymph of Mediterranean mussels Mytilus galloprovincialis Lamarck, 1819 exposed to a wide range salinities (6, 10, 14, 24, 30 ppt). Mussels were captured at shellfish farm with 18 ppt then hypo- hypersaline conditions laboratory. Indicators redox balance hemocytes (intracellular reactive oxygen species (ROS) levels, DNA damage) (thiobarbituric acid substances (TBARS), protein carbonyls (PC), activity catalase (CAT), superoxide dismutase (SOD) glutathione peroxidase (GPx) measured.

Through a 30-day experiment, this study investigated the effects of five photoperiods (0L:24D, 6L:18D, 12L:12D, 18L:6D, and 24L:0D) on survival, enzyme activity, body color, growth-related gene expression redclaw crayfish (Cherax quadricarinatus) juveniles. The results showed that C. quadricarinatus juveniles under 18L:6D 24L:0D exhibited highest survival rate, which was significantly higher than rates other three (p < 0.05). However, 0L:24D group had final weight gain surpassing those groups Regarding activity hormone levels, photoperiod relatively superoxide dismutase (SOD), acid phosphatase (ACP), lysozyme (LZM) enzymes photoperiods, but their levels melatonin cortisol were low. In addition, malondialdehyde (MDA) content.

Macrobrachium rosenbergii is an essential species for freshwater economic aquaculture in China, but the larval process, their salinity requirement high, which leads to stress water. In order elucidate mechanisms regulating response of M. acute low-salinity exposure, we conducted a comprehensive study exposed different salinities’ (0‰, 6‰, and 12‰) data 120 h. The activities catalase, superoxide dismutase, glutathione peroxidase were found be significantly inhibited hepatopancreas muscle following resulting oxidative damage immune deficits rosenbergii. Differential gene enrichment transcriptomics indicated that induced metabolic differences inflammatory dysfunction differential expressions MIH, JHEH, EcR genes inhibition growth, development, molting ability At proteomic level, low affected biological cellular regulation, as well response.

Salinity is a crucial environmental factor influencing the survival, growth, development, and reproduction of aquatic animals. However, underlying molecular mechanisms shrimp’s response to salinity stress are not yet fully understood. Therefore, we used Illumina NovaSeq 6000 platform perform transcriptome sequencing hepatopancreas Litopenaeus vannamei under high-salinity (30 PSU), medium-salinity (10 low-salinity (0.5 PSU) conditions. We obtained 63.23 Gb high-quality data identified 3589 differentially expressed genes (DEGs), including 1638 upregulated 1951 downregulated genes. Notably, comparison between control group revealed that BBOX1 CHE1 were significantly upregulated, while ACOX1, MPV, CYP2L1, GCH, MVK, TREt1, XDH downregulated. These primarily involved in key metabolic pathways, such as fatty acid oxidation, cholesterol metabolism, hormone synthesis metabolism. The β-oxidation, ACAD, HADH, HSD17B4, PECR, CROT, PIPOX, CG5009, all showed downward trend, suggesting L. may respond salt by regulating oxidative optimizing energy utilization, maintaining cell homeostasis Functional annotation gene ontology (GO) KEGG pathway enrichment analysis highlighted roles these significant DEGs adaptation environments varying salinity, underscoring importance pathways their adaptive physiological responses. This study provides biological basis for understanding protection strategies stress.
