Summary: This study investigated the effects of high salinity on the razor clam Sinonovacula constricta and found that the clam can adapt to moderately high salinity through osmotic adjustment. However, salinity higher than 40 ppt can cause severe damage to the clam, so it is recommended to maintain seawater salinity below 30 ppt for aquaculture.

Summary: This study aimed to explore the optimal light intensity for the breeding of Sinonovacula constricta. The results showed that light intensity had significant effects on the spawning amount, initial spawning time, and survival rate of different developmental stages of S. constricta. However, it had little influence on the hatchability of fertilized eggs. These findings suggest that light intensity affects the growth of S. constricta at different stages, and each stage exhibits distinct sensitivity to light intensity.

Summary: This study investigates the relationship between gut microbiota and the growth of razor clams. The results show that there is a significant difference in gut bacterial community structures between retarded and overgrown clams, as well as between retarded and normal ones. The gut bacterial community variations are positively correlated to digestive enzyme activities, which subsequently influence clam growth traits. The distribution and shifts of gut keystone species are closely related to clam growth traits. The relative abundances of gut bacterial-mediated functional pathways involved in metabolism are significantly different between retarded and normal clams.

Summary: In this study, microplastics were found in all samples of Sinonovacula constricta from Zhangzhou City, with smaller sizes. The farm samples had a higher abundance (3.65 n/g) than the market samples (0.89 n/g), mainly due to body fluid contribution. Microplastics transported from body fluid to viscera and metabolized into muscles were significantly reduced (69.3%), with only 0 or 1 microplastic observed in micron-scale muscles. Microplastics in market samples were mainly concentrated in viscera (81%), while they were distributed in all organs of farm samples, with body fluids accounting for 52%. Four shapes of microplastics were detected, with the highest percentage of fibrous shape. Foam-like microplastics were not detected in market samples. The abundance was not correlated with sample weight, but market samples showed a positive correlation. Seven polymers were detected, with the highest rate of polypropylene (PP) (27%). The polymer risk level reached level III. Despite their lower abundance, market samples had a higher hazard risk index due to a higher percentage of polyvinyl chloride (PVC) compared to farm samples. The cleaning process and excretory behavior from farms to markets greatly reduced microplastic contamination.

Summary: This study investigates the light entrainment of the molecular circadian clock in Sinonovacula constricta, an important bivalve species. The results reveal the presence of a clock system consisting of seven closely related genes. These genes are expressed in all tissues, with high expression in the labial palps and hepatopancreas. Different clock genes display daily or circadian rhythms under different light conditions, indicating the adaptation of the circadian system to various light environments. Differences in gene expression patterns between the labial palps and hepatopancreas suggest tissue-specific regulation of the circadian system. Overall, this study provides insights into how the circadian oscillators of S. constricta respond to light and may have implications for optimizing light environments in the farming industry.

Summary: Today, authoritarian states, including China, use state-run propaganda operations to cultivate political loyalty among their diasporic subjects beyond national borders. By disseminating carefully tailored discourses, penalizing opposing voices, promoting a unified interpretive framework, forming a standard meaning system, coordinating collective action, and fostering an integrated patriotic identity, autocratic states aim to construct a stable, exclusive, and institutionalized diasporic network of influence within host societies. This unprecedented forging of solidarity among diasporic Chinese is attributed to China's extraterritorial propaganda, which relies on concise, catchy, and carefully tailored symbolic resources to extend political influence beyond national borders. This poses novel challenges to the traditional concept of the sovereign state.
