Summary: This study found that smaller mussels ingest more microplastics, but the uptake rate decreases as mussels grow larger. The predominant types of MPs in mussels are fiber and blue in color, with PE and PP being the most common polymers. The distribution of MPs in mussels closely resembles that in water, and there is no significant difference in MPs quantities between P. viridis and P. perna.

Summary: Understanding the pathogenicity and immunity in disease-resistant mollusk varieties is crucial. This study isolated pathogenic Vibrio alginolyticus from infected Perna viridis and observed histopathological and immunological changes after challenge tests. The results demonstrated the pathogenicity of V. alginolyticus in P. viridis, causing organ lesions and decreased immune function.

Summary: Recent studies have shown that organisms, including humans, are exposed to microplastics, both directly and indirectly. This study specifically focused on the accumulation behavior of weathered Polyethylene (wPE) microplastics in Perna viridis, revealing that higher concentrations of wPE led to decreased feeding rates and increased accumulation in the intestines of exposed organisms. Biomarker analysis also showed significant alterations in metabolism and histology due to wPE exposure, highlighting the potential adverse effects on internal organs and overall marine ecosystem health.

Summary: This study investigated phytoplankton and copepoda in the industrialized Gabes coast and found that the community composition is affected by eutrophication. Intensive agrochemical activities and rapid population growth have led to high concentrations of nutrients and eutrophication in the seawater. Bacillariophyta was the most abundant group, and certain species showed positive correlation with the eutrophication index. The diversity index of phytoplankton and copepoda showed negative correlations with the eutrophication index, indicating their sensitivity to eutrophication.

Summary: The periostracum, an outer coating on the shells of bivalves, plays a crucial role in their growth and survival, but has been little studied. This research uses microscopy to investigate the structure and variation of the periostracum in the green mussel. It reveals a novel sandwich-like structure with different layers and significant variation in thickness along the shell edge. The study provides new insights into the formation mechanism of the periostracum and its potential applications in biomimetic coating and photonic materials.

Summary: The study found differences in the composition and abundance of phytoplankton in areas near and far from shrimp farm discharge, with greater richness and diversity in the area far from the discharge. Higher phytoplankton abundance was observed when farms were operating or finishing operations. Shrimp effluents impact phytoplankton composition and abundance, reducing species richness and diversity while increasing abundance.

Summary: This study examined the effects of suspended particles (SP) on the filtration rates of the green-lipped mussel Perna viridis in Thai coastal waters. The results showed that exposure to SP significantly decreased the filtration rates of the mussels, and gill abnormalities were detected. The size and exposure time also influenced the filtration rates.

Summary: This study is divided into two parts. The first part verifies the presence of microplastics in bivalves using microscopy and Fourier transform infrared spectroscopy. The second part explores the knowledge, attitude, and perception of bivalve gleaners on microplastics and plastics. Results confirmed the presence of microplastics in both bivalves, with polyamide fibers being the most common polymer found. The average size of microplastics in Perna viridis and Venerupis spp. was 0.25 +/- 0.05 mm and 0.33 +/- 0.03 mm, respectively. Varying colors and shapes were observed. The gleaners showed a lack of knowledge about microplastics but had a positive attitude towards reducing plastic pollution and valued coastal waters. The estimated amount of microplastics transferred to humans through bivalve consumption was 0.003 mg/day.

Summary: In this study, the distribution of ABC transporters in the mussel Perna viridis was analyzed comprehensively, and the responses of ABCB and ABCC transporters to DSP toxins-producing dinoflagellate Prorocentrum lima were observed. The study found that different types of PvABCBs and PvABCCs in P. viridis may contribute to the detoxification of DSP toxins in different tissues at different time after exposure. These findings provide new evidence for understanding the role of ABC transporters in the tolerance of mussels to DSP toxins.

Summary: This study evaluated the effects of stocking density, water depth, and aquaculture gear on the aquaculture performance of Crassostrea angulata. The results showed that both stocking density and water depth had an impact on the survival and growth rate of C. angulata. In the nursery phase, high stocking density was beneficial for growth but reduced survival, while 1.5 m and 3 m water depth were optimal. In the grow-out phase, lantern net/rope culture, low stocking density with narrow substrate spacing, and shallow water (1.5 m) were beneficial for survival, growth, and yield. These findings provide important guidance for improving C. angulata aquaculture practices and filling knowledge gaps.

Summary: Bivalves can be affected by harmful algal blooms (HABs) and their toxins, leading to changes in behavior, physiology, and cellular responses, and even mortality. The immune system and resistance of bivalves to environmental stressors can also be negatively impacted by exposure to HABs and their toxins.

Summary: This study investigates the mechanism of sex reversal in bivalves and its impact on offspring productivity using the noble scallop as a model species. The results demonstrate that sex reversal in scallops is influenced by water temperature and age, and it does not compromise the reproductive ability but can improve the growth rates of their offspring.

Summary: With the development of intelligent electronic power systems, the demand for flexible electronic sensors with portability and miniaturization has increased. Researchers have successfully prepared a series of spider-web-like cross-linked polyimide aerogels (CPAs) that exhibit excellent compressive resilience, tunable dielectric permittivity, high thermal insulation property, and modulus. By combining the CPAs with carbon nanotubes, a composite aerogel-based strain sensor with enhanced sensitivity, selectivity, and stress detection capabilities was achieved. The established mathematical model revealed the internal mechanism of the synergistic enhancement of sensing performance. These findings have important implications for the fabrication of flexible electronic sensors and improving their sensitivity and detection limits.

Summary: This study investigates the effects of a homogenous porphyran from Porphyra haitanensis (PHP) on the intestinal barrier and gut microbiota. The results show that PHP can improve the intestinal barrier function and regulate the composition of gut microbiota in mice. PHP increases the growth of beneficial bacteria, enhances the production of short-chain fatty acids, and improves the physical barrier function of the intestines. Furthermore, PHP increases the richness and diversity of gut microbiota and the ratio of Firmicutes to Bacteroidetes.

Summary: This study comprehensively reviewed the presence of radionuclides in marine bivalves. It was found that bivalves have the ability to accumulate high levels of radionuclides, but the accumulation varies in different species and tissues. Most radionuclides enter the bivalves through the trophic pathway, while some others are absorbed along with other minerals and selectively accumulate in the shells. The information from this study provides an overview of radionuclide contamination in marine bivalves.

Summary: This study analyzes the fatty acid composition of various bivalves from different regions and times, and finds that global warming has a significant negative impact on the lipid content and lipid indices of temperate bivalves, but has a smaller impact on bivalves in other regions. The decline of aragonite saturation state in seawater promotes the lipid accumulation in tropical and subtropical bivalves, but compromises the lipid indices of bivalves in all regions. This study fills the knowledge gap of the impact of climate change on the lipid nutritional quality of bivalves and provides guidance for bivalve aquaculture and fisheries management plans.
