Summary: The study focuses on the impact of benthic marine organisms on nitrogen cycling and the importance of this in restoring coastal ecosystems. By measuring the removal and respiration rates of nitrogen in restored beds, it was found that sediment organic matter is a significant predictor of denitrification rates. Additionally, the biodeposition by green-lipped mussels was shown to enhance nitrogen removal, providing insights for future restoration efforts.

Summary: Marine heatwaves have significant impacts on aquaculture species like the New Zealand green-lipped mussel. This study investigated the survival, physiological responses, and immune defense mechanisms of adult mussels exposed to different seawater temperature regimes. The results showed that the mussels exhibited metabolic adjustments, immune responses, and changes in the metabolome to cope with thermal stress. The findings provide valuable insights for future targeted investigations and management of aquaculture.

Summary: Globally, local species are being used for ecotoxicological risk assessments. Anthropogenic stressors can impact the health of receiving ecosystems, and biomarkers can provide valuable insights. This study developed and validated gene expression assays in the green-lipped mussel to assess its potential as a bioindicator for environmental risk assessment. Significant modulation of genes associated with oxidative stress, xenobiotic transfer, membrane transport, endocrine disruption, and genotoxicity were observed in the mussel following exposures to copper and benzo[a]pyrene.

Summary: The green-lipped mussel is an important species in New Zealand, but harmful algal blooms of Alexandrium spp. and reduced wild spat catch have posed a threat to its development. This study investigated the effects of Alexandrium pacificum and A. minutum on the development of mussel larvae and found that both species negatively impacted early life stages, with A. pacificum causing lysis of embryos and reduced larval growth. The findings highlight the potential harm of Alexandrium spp. blooms to the vulnerable early life stages of the green-lipped mussel.

Summary: Microplastics were found in green-lipped mussels collected from five mariculture sites in Hong Kong, with an average of 1.60-14.7 particles per mussel per site. It was estimated that the population in Hong Kong could ingest up to 10,380 pieces of microplastics per person per year through consumption of these contaminated mussels, indicating a potential human health risk in the region.

Summary: This study investigates the effects of pathogen coinfection on the survivability and immune responses of New Zealand's Greenshell mussel. The results show that coinfection leads to 100% mortality in both adult and juvenile mussels, and the bacterial counts in the haemolymph decrease over time. Metabolomics analysis reveals significant changes in energy metabolism for mussels infected with Vibrio mediterranei, while no metabolic differences are observed for mussels infected with Photobacterium swingsii.

Summary: This study aimed to confirm the use of marine mussels' byssus (BYS) as a biomonitoring biopolymer for zinc (Zn) by comparing it to copper (Cu) and cadmium (Cd) pollution in coastal waters. The results showed that BYS was a more sensitive and accumulative biopolymer for the three metals compared to total soft tissues (TST). Additionally, BYS was a better biomonitoring biopolymer for identifying coastal areas exposed to Zn, Cd, and Cu pollution and demonstrated the role of the BYS as a route for the excretion of metal wastes. Furthermore, BYS was more reflective of metal bioavailability and pollution in coastal waters.

These activities not only pose a threat to biodiversity, but also impact the lives and livelihoods of those who depend on the high seas. To address this, a high seas horizon scan was conducted to identify the most pressing research questions and priorities for the future of the high seas. The results can inform international efforts to protect and sustainably manage these areas.

Summary: This study investigates the effects of thermal stress and immune stimulation on New Zealand Green-lipped mussels. The results show that thermal stress increases energy demand and metabolic rate, while endotoxin exposure leads to increased metabolic response in terms of protein and lipid degradation. Additionally, higher temperature has a severe physiological impact on mussels, but the combination of thermal stress and endotoxin treatment does not have a synergistic effect on mortality. These findings provide new insights into the immune defence system of mussels.

Summary: The occurrence of pathogenic bacteria has been identified as a key factor in summer mortality events in mussels. In this study, four bacterial isolates were obtained from moribund Greenshell mussels and identified as Vibrio and Photobacterium species. The isolates were tested in a laboratory challenge and it was found that P. swingsii induced the highest mortality. Additionally, the presence of virulence genes was detected in all isolates, with Photobacterium rosenbergii and P. swingsii showing the highest expression levels. These findings suggest that Photobacterium spp. may play a significant role as a pathogen in P. canaliculus during summer mortality events.

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.
