“…Nonnegligibly, changes of SOD might also be attributed to oxidative stress induced by saline variation [27,28], or comprehensive effects of oxidative stress and innate response. Moreover, decreased SOD activities were observed in some treatments, which was similar to the results detected in Echinometra lucunter in response to hypersaline treatment [23]. The underlying mechanisms required further investigations.…”

“…Activities of antioxidant enzymes and the levels of ROS have been found to correlate with various stress [22]. ROS generation is an essential mechanism during phagocytosis [23]. Besides, ROS level is a common feature representing oxidative stress in animals exposed to abiotic stress.…”

“…Besides, ROS level is a common feature representing oxidative stress in animals exposed to abiotic stress. Treatments with hypersalinity generally induce production of reactive oxygen species (ROS) in aquatic animals [23,24], which are harmful to protein, lipid, DNA molecules, and finally damage cytomembrane, enzyme activity and cell function. To resist ROS, organisms may initiate a series of antioxidant reactions [25,26].…”

During the production of desalination plants, concentrated seawater is expelled to local marine environments, which may lead to hypersaline pollution. To assess environmental risk of hypersalinity, Crassostrea angulate, Scylla paramamosain and Epinephelus akaara were exposed to salinities of 30‰, 36‰ and 40‰, then changes of serum nonspecific immune indices were monitored for 96 hours, including superoxide dismutase (SOD) and acid phosphatase (ACP) activity, and contents of serum total protein and albumin. Two-way ANONA revealed that salinity only affected contents of serum total protein and albumin in C. angulate, and content of serum albumin in S. paramamosain and content of serum total protein in E. akaara. Compared with the control, hypersaline treatments (36‰ and/or 40‰) first increased contents of serum total protein and albumin and then decreased them in C. angulate, suppressed content of serum albumin in S. paramamosain, and increased content of serum total protein in E. akaara. These results suggested that exposure to hypersalinity might enhance innate immunity of C. angulate and E. akaara, but suppressed it in S. paramamosain.

“…The energy used for osmotic pressure adjustment can account for 20%–50% of the total energy consumption (Ern, Huong, Cong, Bayley & Wang, ). Although some organisms can tolerate a wide range of salinity, changes in salinity have an impact on the growth, development, metabolism and immunity of aquatic organisms (Bertucci et al., ; Honorato, Boni, da Silva & Marques‐Santos, ; Lee et al., ; Moorman, Yamaguchi, Lerner, Grau & Seale, ). The optimal salinity for growth and development varies for different species (Chand et al., ; Le et al., ).…”

In this study, we evaluated the growth, osmoregulation and energy metabolism of the oriental river prawn, Macrobrachium nipponense, reared during 6 weeks with different salinities (0, 8, 14 and 22 g/L). The results showed that the haemolymph osmolality of M. nipponense increased with an increase in ambient osmotic pressure; the isosmotic point was 490 mOs/kg H 2 O. The prawns showed a higher survival rate, weight gain rate and hepatopancreas index in salinity 14 g/L. Digestive enzymes were all affected by salinity, and the highest activities were observed in the salinity 14 g/L. The mRNA expression of Na + -K + -ATPase in gills and p53 in hepatopancreas were the highest in salinity 22 g/L. The expressions of heat shock protein 90 and glutathione S-transferase genes in hepatopancreas were significantly higher in the salinity 8 g/L. Lipid metabolism-related genes in hepatopancreas were significantly expressed in the salinity 14 g/L. The glucose-6-phosphatase gene in hepatopancreas was highly expressed in the salinity 8 and 22 g/L, and the expression of the ecdysone receptor gene in hepatopancreas was significantly higher in the salinity 14 g/L. The results showed that salinity 14 g/L could promote the growth of M. nipponense. However, higher salinity conditions may cause physiological damage, which provides a theoretical basis for brackish water culture of M. nipponense.

“…At the cellular level, the stress boosts osmolyte concentration imbalance between cells and their environment, followed by a lesion of electrochemical potential of cellular membranes (Pierce, 1982;Stucchi-Zucchi and Salomao, 1998). Osmotic stress deeply affects various physiological processes, including those in nervous, immune and other systems (Stucchi-Zucchi and Salomao, 1998;Cheng et al, 2004;Bussell et al, 2008;Jauzein et al, 2013;Honorato et al, 2017). Considerable progress has been made in recent years in our understanding of the molecular background of salinity adaptation (An and Choi, 2010;Hoy et al, 2012;Lockwood and Somero, 2011;Zhao et al, 2012;Tomanek et al, 2012;Meng et al, 2013;Seveso et al, 2013;Carregosa et al, 2014;Muraeva et al, 2016;Gharbi et al, 2016;Yang et al, 2016;Yan et al, 2017).…”
