Summary: In this study, consecutive four generations of mass selection were conducted to evaluate the viability, growth, ploidy, and fertility of tetraploid Pacific oyster progenies. The study found that the improvement of progeny viability was mainly influenced by gamete quality, while growth traits were significantly improved through mass selection. Furthermore, the ploidy-level of tetraploid progeny differentiated and transformed in the early stage of gametogenesis. After three generations of selection, the proportion of tetraploid progeny increased significantly.

Summary: This study compared the fillet nutritional quality of diploid and triploid rainbow trout with the same genetic background, farming condition and body weight. The results showed that diploid trout had higher protein content and amino acid scores, while triploid trout had higher lipid content and fatty acid scores. Both types of trout were suitable for human consumption and had beneficial effects on health. However, triploid trout had higher mineral content and differed in nutritional composition compared to diploid trout. The difference in lipid metabolism may be the reason for these variations.

Summary: Inbreeding in Pacific oysters was found to have negative effects on growth and survival traits, leading to lower heritability in growth traits but no significant impact on survival rate heritability. This suggests that there is potential for selection in survival traits in inbred populations, which could be valuable for shellfish breeding programs.

Summary: Meagre is a target species in European marine aquaculture due to its high growth rates and nutritional profile, but it is highly sensitive to low temperatures. This study examined the effects of dietary phospholipids (PLs) on the growth and cold tolerance of meagre, finding that a PL-enriched diet promoted faster growth and reduced the risk of death, as well as mitigated the negative effects of fatty liver during cold challenges. These results suggest that dietary supplementation with phospholipids could improve the cold tolerance of meagre in aquaculture.

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: 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.
