Summary: This study compared the adaptation of tetraploid and diploid larvae to salinity and temperature, and found that tetraploid larvae have lower survival rates and growth rates than diploid larvae. The study also determined that a salinity range of 25-30 psu and a temperature range of 23-28℃ are the most suitable conditions for culturing tetraploid larvae.

Summary: This study investigated the physiological and immunological response of Crassostrea nippona to low salinity. The results showed that low salinity led to hyperosmolality in the hemolymph and differential gene expression in the gill transcriptome. The study provides insights into the immune mechanism of C. nippona under low salinity stress.

Summary: Hybridization experiments between Crassostrea ariakensis and C. gigas were conducted multiple times, with the difficulty of obtaining a large number of hybrid offspring identified as a bottleneck in subsequent cross-breeding efforts. The study found that the appropriate salinity levels during artificial insemination led to higher fertilization rates, while optimal salinity levels for embryo incubation and larval growth and survival varied between the two species. These findings are expected to contribute to increased hybrid progeny yield and genetic improvement in oyster germplasm.

Summary: This study investigated the effects of depuration salinity and duration on anhydrous living-preservation in Pacific oysters. The results showed that prolonged duration and significant salinity fluctuations increased the mortality rate and disrupted metabolism in oysters, and the changes in protein expression profiles were mainly associated with amino acid metabolism.

Summary: In this study, the effects of diel-cycling hypoxia under different salinities on fatty acid composition and lipid metabolism in the oyster Crassostrea hongkongensis were evaluated. The results showed that both hypoxia and elevated salinity caused a decrease in the saturated fatty acid (SFA)/polyunsaturated fatty acid (PUFA) ratio of C. hongkongensis. Changes in specific fatty acids were mainly induced by salinity, while hypoxia accelerated the synthesis of certain fatty acids. Additionally, the activity of hepatic lipase (HL) and lipoprotein lipase (LPL) was affected by both salinity and dissolved oxygen. The findings indicate that exposure to combined stressors of salinity and hypoxia can disrupt the protective mechanisms of oysters and affect their lipid metabolism.

Summary: In this study, we investigated the morphological differences in the shells of Jinjiang oysters from six populations along the coast of China. The color of the shell and adductor muscle scar showed associations with temperature gradient along its geographical distribution. Shell shape was defined by shell height to shell length ratio, and the ratio varies among geographic locations of the populations. We also developed a method to measure the cavity volume in oysters. The linear equation for shell height and cavity volume under different ratios of shell height to length was obtained.

Summary: The study reveals that diel-cycling hypoxia and salinity changes have significant impacts on the immune function of the Hong Kong oyster, with hypoxia and low salinity causing more severe effects. Recovery from the combined stress showed that some immune parameters were restored to normal levels, but hemocyte mortality and reactive oxygen species were still significantly affected, indicating latent effects of diel-cycling hypoxia and salinity changes on oyster health.

Summary: The study found that high salinity triggered abnormal respiratory metabolism and enhanced glycolysis in oysters, leading to glycogen decomposition, lactic acid increase, and fatty acid composition modifications mediated by AMPK. After 72 hours of depuration, there was a significant decrease in the condition index and meat yield of oysters, especially under high salinity of 38 g L-1.

Summary: Salinity changes in the oceans due to climate change affect the biology and immune responses of oysters like C. corteziensis. High salinity stress conditions pose a greater challenge to the oysters compared to low salinity stress conditions, potentially increasing vulnerability to other environmental stressors and diseases.

Summary: Our study found that periodic hypoxia/reoxygenation combined with salinity changes induced antioxidant responses in Hong Kong oysters, with significant interactive effects of salinity, dissolved oxygen, and their interactions on oxidative stress parameters. These findings suggest that salinity stress, in combination with hypoxia/reoxygenation conditions, may impact the health of the oysters and could be a contributing factor to mortality in aquaculture processes.

Summary: This study investigated the effects of periodic hypoxia and salinity changes on the oxidative stress response in Hong Kong oysters. The results showed that the combination of hypoxia/reoxygenation and decreased salinity had the most severe effect, leading to increased oxidative stress parameters. Prolonged salinity stress may contribute to the mortality of Hong Kong oysters during aquaculture.

Summary: In this study, the effects of diel-cycling hypoxia and salinity change on Hong Kong oyster physiology were examined. The results showed that the oysters' metabolism gradually shifted from aerobic respiration to glycolysis under these conditions, and their gill functions were also affected. Long-term exposure to these conditions poses a risk to the health and growth of Hong Kong oysters, as well as the aquaculture and coastal ecosystem health.

Summary: Glycogen, an important energy form for aquatic shellfish, contributes to the flavor and quality of oysters. In this study, the genes GYS and GSK3 beta were identified and their functions in glycogen synthesis were explored. The expression of GYS was positively correlated with glycogen content, while the expression of GSK3 beta was negatively correlated. Knockdown of GSK3 beta reduced GYS expression, indicating its negative regulatory effect.
