Summary: The use of 12 μM EDTA in rearing seawater improves GreenshellTM mussel larval yields by reducing metal bioavailability during the first 48 hours, but has minimal benefit on larval fitness between day 2 and 21. The biological regulation of elements such as Al, P, Cr, Fe, Co, Ni, Zn, As, Cd, and Hg in the rearing process is just as important as metal bioavailability for larval development.

Summary: This study aimed to identify reliable screening biomarkers in the early life stages of selectively-bred/hatchery reared green-lipped mussel through lipid quantification using confocal laser scanning microscopy and image analysis, as well as Iatroscan thin layer chromatography/flame ionization detection. The results showed that both methods were successful in detecting differences among larval groups with different genetic backgrounds and growing environments, providing important insights for early screening.

Summary: The research focused on developing a cook-then-ferment technology to extend the shelf life and safety of ready-to-eat mussels by destroying endogenous microflora. The results showed that this method effectively reduced common pathogens such as Staphylococcus aureus, Salmonella, and Vibrio parahaemolyticus, while also inhibiting Listeria monocytogenes with a specific strain of Lactobacillus sakei in a culture, suggesting potential applications for other novel foods.

Summary: This study investigated the efficacy of immersing Cultured Greenshell mussels in prickly pear cactus solutions. It was found that low concentrations of prickly pear cactus powder and extract can enhance the mussels' resilience to thermal stress. This research provides evidence for the potential use of bioactive plant extracts to improve physiological resilience in shellfish species.

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: The Greenshell mussel is the most profitable aquaculture species in New Zealand, but losses of commercial juvenile mussels are common and can significantly reduce adult yield. Modifying seeding density is a potential method to manage loss of juvenile mussels by reducing biofouling and competition. Understanding stress responses in mussels during early aquaculture stages is crucial for optimizing mussel production.

Summary: Major losses of early juvenile seed mussels or spat are a typical feature of aquaculture production, caused by predation, mortality, and migratory behavior. The study indicated that utilizing a floating upwelling system (FLUPSY) for raising Greenshell(TM) mussel spat could significantly reduce losses and improve production efficiency.

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: The addition of crushed shells in high PCO2 seawater partially mitigated the negative effects on P. canaliculus larvae. Other factors such as non-buffering effects of crushed shell, parental pool, and inclusion of a chelator (EDTA) in seawater seemed to have a bigger impact on larval performance than buffering itself, indicating the need for further investigation.

Summary: The study investigates the impact of two probiotic yeasts on the microbiome and neutrophil response in zebrafish larvae, showing that they can modulate the microbiota configuration, reduce inflammation, and enhance survival rate. Yeast pre-inoculation prevents changes in key taxa and metabolic pathways induced by pathogen infection, highlighting the important role of yeasts in shaping the microbiome and influencing the survival of infected larvae.

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.
