Summary: Invasive non-native species, such as the Pacific oyster, are likely to undergo significant range expansion due to global warming, impacting native biodiversity and ecosystems. The management and perception of these naturalized populations will be key in determining their overall impact on human society and the environment.

Summary: The mortality of Crassostrea gigas juveniles is systematically observed every year worldwide, primarily due to Pacific Oyster Mortality Syndrome (POMS) caused by OsHV-1 infection. During the oyster mortality episode, releases of OsHV-1 and opportunistic bacteria were observed in the water, potentially impacting disease spread within oyster farms and marine biodiversity in shellfish farming areas.

Summary: Oxidative stress was observed in Pacific oysters (Crassostrea gigas) exposed to high temperature both in indoor experiments and during outdoor aquaculture period. The oxidative stress indicators (SOD, CAT, POD, T-AOC, MDA, and GSH) showed significant changes, with a decrease observed at 28°C in the high-temperature treated groups. During the outdoor aquaculture period, MDA content decreased significantly with increasing temperature. Overall, these findings provide valuable insights into oxidative stress in Pacific oysters exposed to high temperature.

Summary: The study evaluated the impact of larval stocking density on larval yield, competent larvae, and larval shell length of Crassostrea gigas in a recirculation aquaculture system (RAS). Results indicated that the optimal densities for larval rearing were 50 and 75 larvae mL-1, leading to the best growth and highest proportion of competent larvae. This RAS approach could enhance resource efficiency and profitability for commercial hatcheries.

Summary: In recent years, there has been a high mortality rate of cultured Pacific oysters in Baynes Sound, Canada. This study aimed to investigate the potential causes of oyster mortality by examining bacterial diversity, oyster reproductive development, and environmental factors. The results showed that the mortality rate was correlated with date, tides, temperature, gonad somatic index, and gonad developmental phase. Pathogenic bacteria, including Vibrio aestuarianus and V. harveyi, were identified in the oysters. This study provides evidence that the summer mortality of Pacific oysters in Baynes Sound has a similar etiology to that in other countries.

Summary: This study investigated the distribution of eight invasive species in Santa Catarina, Brazil, the main mussel production area in the country. The results showed that these species were present in all sites, but their distribution was spatially restricted for both adult and recruit individuals. Propagule pressure was found to be the main driver of distribution for three species, while port distance only explained the distribution of one species.

Summary: A study on the growth potential of Pacific oysters in the South African marine environment was conducted using satellite data and a model. The study found that the eastern nearshore sectors of the South Coast and the northern sectors of the West Coast have high growth potential. However, the South Coast has variable growth conditions. The existing oyster production sites were found to be suboptimal for growth, and high-growth areas coincided with areas of economic decline or high poverty levels.

Summary: This study surveyed and established a baseline for the ascidian biofouling community in a coastal lagoon using artificial substrate units (ASU) made from oyster shells. The results showed that ASU can be considered an efficient support structure for monitoring the ascidian community and fouling communities in general. Additionally, two ascidian species were recorded for the first time in coastal waters of mainland Portugal.

Summary: The study revealed the endolithic parasitism of R. dubia in the shells of the Pacific oyster, potentially causing significant damage to the oysters and indicating a possibly widespread parasitic association. This association has been overlooked due to the scarce research on macrofauna associated with M. gigas.

Summary: Selective breeding programs have been initiated for the Pacific oyster Crassostrea gigas, using genomic tools to improve growth and disease resistance. The study evaluated the potential of genomic selection (GS) for growth-related and shell color traits in commercially selected populations. The results showed a high correlation between growth-related traits and low correlation with color traits. The accuracy of prediction was higher with the genomic model compared to the classical model, indicating the potential of GS in mixed-family breeding programs for C. gigas.

Summary: This study investigated the transfer of fatty acids from broodstock diets to eggs and the time needed for the eggs to equilibrate to the diet in Southern flounder. The findings indicate that different diet treatments significantly affect the fatty acid composition of eggs, and it takes 8-16 weeks for the eggs to adapt to changes in the adult diet. These results are important for improving broodstock diets and feeding protocols in stock-enhancement programs.

Summary: This study developed a centrifugal microfluidic chip with on-chip RPA to detect five pathogenic microorganisms. The chip enabled the parallel analysis of six genetic markers from a single sample and allowed for the highly automated detection of multiple samples. Compared with PCR and DNA sequencing, the on-chip RPA assay showed high sensitivity and specificity for detecting multiple pathogens in shrimp aquaculture.
