“…Na + -K + -ATPase is an ion channel that uses the energy generated by ATP hydrolysis to maintain membrane potential by driving three Na + outlets and two K + intents, which is essential to osmotic regulation (Evans and Lambert, 2015;Abdel-Mohsen, 2016). In this study, after 12 h and 24 h of salinity stress, Na + -K + -ATPase activity of P. fucata with black shell in low-salt and high-salt groups was significantly lower than that in the control, showing an inverted U-shape distribution.…”

This study compares salinity tolerance between red and black shell Pinctada fucata salinity stress of 20 and 50‰, while 35‰ was used as a control. The hemolymph osmotic pressure, inorganic ion concentration, the activities of Na+-K+ -ATPase, respiratory metabolism related enzymes and liver tissue antioxidant related enzymes were measured at 12 and 24 h after salinity stress. The osmotic pressure and inorganic ion concentration of hemolymph of two strains P. fucata increased significantly with the increase of salinity. The activity of Na+-K+ -ATPase of red P. fucata only decreased under low salinity at 24 h, and was significantly higher than that the control under low salinity at 12 h and high salinity at 12 and 24 h. The succinate dehydrogenase (SDH) activities of the P. fucata treatment groups were significantly higher than those the control at 12 h. The lactate dehydrogenase (LDH) activity increased significantly with salinity at 12 h. and the black P. fucata LDH activity was significantly higher than the control at 24 h, while the LDH activity of red P. fucata was significantly lower than that the control in 50‰ salinity. The superoxide dismutase (SOD) activity of black P. fucata was significantly lower than that the control, while that of red P. fucata was significantly higher than that the control within 24. At 12 h, the catalase (CAT) activity of red P. fucata increased significantly with salinity, but decreased significantly with salinity at 24 h. The CAT activity of black P. fucata was highest at 24 h under low salinity. Glutathione peroxidase (GSH-Px) and alkaline phosphatase (AKP) activities of red P. fucata were significantly higher than those the control under low or high salinity. At high salinity for 24 h, the GSH-Px activity was lowest in black P. fucata, AKP activity was highest. The present study indicates that the physical responses of P. fucata to the salinity stress vary with shell colors. The red P. fucata can quickly respond positively to the change of environmental salinity and reduce the damage caused by the change of environmental salinity.

“…It has also been found that following RT‐PCR and phosphorImaging analysis, G6PD transcript in a salinity of 6‰ was down‐regulated compared with 12‰ of Sparus sarba (Deane & Woo, 2005). L‐lactate dehydrogenase (LDH) is a key enzyme in the glycolytic pathway and the tricarboxylic acid cycle, and its activity can be used as an indicator of anaerobic metabolism (Abdel‐Mohsen, 2009). In this study, LDH in the LS group was significantly down‐regulated compared with the HS group after overwintering.…”

“…SDH plays a key role in the TCA cycle and also is involved in oxidative phosphorylation, so the activity of SDH can reflect the level of aerobic metabolism to some extent (Metón, Fernández & Baanante ). LDH is closely related to cell metabolism and is a key enzyme in glycolysis and the TCA cycle; thus, its activity can be used as a measure of the level of anaerobic metabolism (Valarmathi & Azariah ; Abdel‐Mohsen ). Under red and white light at 4L:20D and 8L:16D, the SDH activity was higher than that under blue light, which suggests that these light qualities and cycles provided a good environment characterized by little stress and energy supplied primarily through aerobic metabolism.…”

The goal of this experiment was to examine the effects of different light qualities (red, white, blue) and cycles (12L:12D, 8L:16D, 4L:20D, 0L:24D, 16L:8D) on the survival, growth, metabolism and antioxidant defence system of Haliotis discus hannai Ino. Under red and white light at 4L:20D, the body weight‐specific growth rate of abalones was significantly higher than that of the 0L:24D group (P < 0.05). At 16L:8D, succinate dehydrogenase activity decreased and lactate dehydrogenase and alanine aminotransferase activity and the lactic acid content significantly rose (P < 0.05) in the red and white light groups. Under blue light, reactive oxygen species and malondialdehyde content for each light cycle were significantly higher than those of the red and white groups (P < 0.05). Under blue, white and red light, total antioxidant capacity (T‐AOC), superoxide dismutase (SOD) activity, glutathione peroxidase (GPX) activity and reduced glutathione (GSH) content gradually rose with increased duration of light exposure. Under red light, significant differences in these parameters were detected between the 4L:20D and 16L:8D groups (P < 0.05). Under blue and white light at 16L:8D, values of T‐AOC, SOD, GPX activity and GSH content were significantly lower than those of the 12L:12D group (P < 0.05). Overall, these results indicate that red light at light cycles of 4L:20D and 8L:16D is optimal for the culture and production of H. discus hannai, as these conditions promoted food intake, growth and health maintenance as well as normal physiological metabolism of the organism.
