“…Studies assessing thermal tolerance in fishes and other aquatic ectotherms have been conducted using freshwater (FW)-acclimated (Barrionuevo and Femandes, 1995;Currie et al, 1998;Elliott and Elliott, 1995;Zaragoza et al, 2008;Zhang and Kieffer, 2014) or SW-acclimated animals (Fangue et al, 2006;Healy and Schulte, 2012a,b;Madeira et al, 2013;Murchie et al, 2011;Tsuchida, 1995), or using comparisons between FW-and SW-acclimated animals (Metzger et al, 2016). However, whether salinity affects thermal tolerance remains inconclusive, varying between species and studies, with some studies reporting an effect of salinity on thermal tolerance (Chen and Chen, 1999;Cheng et al, 2013;Everatt et al, 2013;Jian et al, 2003;Metzger et al, 2016;Sardella et al, 2008a,b), and others reporting no effect at all (Re et al, 2006(Re et al, , 2012Haney and Walsh, 2003). Even among studies reporting an effect of salinity on thermal tolerance, there appears to be no consistency in how thermal tolerance is associated with salinity.…”

The aims of this study were to assess whether thermal tolerance of brook trout () is affected during seawater (SW) acclimation and to investigate the role of cortisol in osmoregulation and thermal tolerance during SW acclimation. Freshwater (FW)-acclimated brook trout at 18°C () were exposed to SW for 16 days, whilst maintaining a FW control. Fish were examined for critical thermal maximum (CT) 0 (before), 2, 5 and 16 days after SW exposure, and sampled at and CT for analysis of plasma cortisol, glucose and Cl, gill Na/K-ATPase (NKA) activity and heat shock protein 70 (HSP70) abundance, and white muscle water content. At 2 days in SW, CT was significantly reduced (from 31 to 26°C), and then recovered by 16 days. This transient decrease in thermal tolerance coincided with a transient increase in plasma Cl and decrease in muscle moisture content. Salinity itself had no effect on gill HSP70 abundance compared with the large and immediate effects of high temperature exposure during CT testing. To examine the role of cortisol in osmoregulation, brook trout were administered a cortisol implant (5 and 25 μg g CORT) prior to SW exposure. Both CORT doses significantly increased their capacity to maintain plasma Cl during SW acclimation. Treatment with the 25 μg g CORT dose was shown to significantly improve CT after 2 days in SW, and CT was associated with plasma Cl and muscle moisture content. These findings indicate that brook trout are sensitive to temperature during SW acclimation and that thermal tolerance is associated with ion and water balance during SW acclimation.

“…Induced thermotolerance (ITT) refers to the ability of an organism to withstand and survive temperatures that otherwise would be lethal (Kir & Kumlu ; Brun et al . ; Denisse Re, Díaz, Ponce‐Rivas, Giffard, Muñoz‐Marquez & Sigala‐Andrade ). In this study, a 30‐min NLHS from 28 to 34, 36 and 38°C followed by 8‐h recovery at 28°C generated thermotolerance in juveniles of C. carpio , promoting survival increases of 20–40% upon exposure to 41°C, the lethal temperature for this fish species.…”

The induction of Hsp70 synthesis by non-lethal heat shock confers thermotolerance and resistance to lethal ammonia stress in the common carp,Cyprinus carpio(Linn)

Exposure to heat‐shock protein (Hsp) stimulating factors induces Hsp accumulation and confers tolerance to lethal ammonia stress on the common carp Cyprinus carpio. This study investigated whether a non‐lethal heat shock bestowed similar protective effects against ammonia and induced thermotolerance, both thought to be rendered by increased amounts of Hsps. The 30‐min lethal temperature (30 min LHT) and 1‐h lethal ammonia concentration (1 h LCT) for this species occurred at 41°C and 14.2 mg/L NH3 respectively. Heating juvenile carp (5 cm) from 28°C to 32, 34 and 38°C, with a subsequent 8‐h recovery period augmented tolerance to lethal heat and ammonia perturbation by two to threefold as compared with animals held at 28°C. Protection occurred in conjunction with Hsp70 accumulation in gills, substantiating the role of this Hsp in enhancing the stress tolerance of common carp.

“…It can fluctuate with weather, precipitation, human disturbance and other factors [ 1 , 2 , 3 ]. Osmotic pressure can change in organisms along with changes in environmental osmotic pressure due to factors such as temperature, salinity and pH [ 4 , 5 , 6 ]. The mechanism of osmotic pressure regulation in aquatic animals has always been an intense topic of global research.…”

Salinity is an important factor in the aquatic environment and affects the ion homeostasis and physiological activities of crustaceans. Macrobrachium nipponense is a shrimp that mainly lives in fresh and low-salt waters and plays a huge economic role in China’s shrimp market. Currently, there are only a few studies on the effects of salinity on M. nipponense. Therefore, it is of particular importance to study the molecular responses of M. nipponense to salinity fluctuations. In this study, M. nipponense was set at salinities of 0, 8, 14 and 22‰ for 6 weeks. The gills from the control (0‰) and isotonic groups (14‰) were used for RNA extraction and transcriptome analysis. In total, 593 differentially expressed genes (DEGs) were identified, of which 282 were up-regulated and 311 were down-regulated. The most abundant gill transcripts responding to different salinity levels based on GO classification were organelle membrane (cellular component), creatine transmembrane transporter activity (molecular function) and creatine transmembrane transport (biological function). KEGG analysis showed that the most enriched and significantly affected pathways included AMPK signaling, lysosome and cytochrome P450. In addition, 15 DEGs were selected for qRT-PCR verification, which were mainly related to ion homeostasis, glucose metabolism and lipid metabolism. The results showed that the expression patterns of these genes were similar to the high-throughput data. Compared with the control group, high salinity caused obvious injury to gill tissue, mainly manifested as contraction and relaxation of gill filament, cavity vacuolation and severe epithelial disintegration. Glucose-metabolism-related enzyme activities (e.g., pyruvate kinase, hexokinase, 6-phosphate fructose kinase) and related-gene expression (e.g., hexokinase, pyruvate kinase, 6-phosphate fructose kinase) in the gills were significantly higher at a salinity of 14‰. This study showed that salinity stress activated ion transport channels and promoted an up-regulated level of glucose metabolism. High salinity levels caused damage to the gill tissue of M. nipponense. Overall, these results improved our understanding of the salt tolerance mechanism of M. nipponense.
