Summary: Infectious diseases in aquaculture are costly to manage and can act as potential vectors for zoonoses. The advancement of Next-Generation Sequencing has revealed the role of the microbiome in disease regulation and resilience. The recognition of a holistic framework in disease aetiology is crucial for the development of new prevention methods, such as identifying biomarkers for dysbiosis prior to physical symptoms.

Summary: The study investigated the gut microbiota of five fish species farmed in the same aquaculture site in Greece, revealing distinct and species-specific microbiota profiles. This suggests that adult farmed fish in the Mediterranean Sea have microbiota profiles that are shaped independently of their similar environmental conditions.

Summary: Salinity changes have significant impacts on the development, physiology, and molecular activity of marine organisms, as well as their associated microbiomes. This study focused on mud crabs, a species with extraordinary adaptability to diverse salinity conditions, to investigate the effects of salinity variations on their gut microbiota. High-throughput sequencing revealed a total of 57 bacterial phyla, with Firmicutes and Proteobacteria being dominant. The gut microbiome of mud crabs showed greater sensitivity to salinity gradients compared to the stomach microbiome. Specific bacterial taxa were enriched in the guts of mud crabs from different salinity settings. Functional enrichment analysis demonstrated significant differences in gut bacterial functions between high and low salinity levels, particularly in signal transduction and cell growth and death pathways. These findings enhance our understanding of the composition and plasticity of mud crab microbiota and have potential implications for the aquaculture industry.

Summary: Atlantic sea scallops are economically important bivalves on the northeastern coast of North America. However, the larval maturation phase in hatcheries is often faced with high mortality events, attributed to bacterial infections or altered microbial communities. This study characterized the bacterial communities in wild and hatchery larvae, as well as tank biofilms, and found that hatchery larvae had lower bacterial richness but similar bacterial community composition to wild larvae and tank biofilms. The fluctuation of bacterial richness and community similarity in tank samples showed correlation to the lunar cycle.

Summary: This study compares the composition of microbiota in the intestines of wild and aquaculture red cusk-eel and finds significant differences between the two. The microbiota in aquaculture conditions is dominated by Firmicutes, while in the wild conditions it is dominated by Tenericutes. Differences in predicted metabolic pathways were also observed, with a focus on lipid metabolism in the wild conditions.

Summary: Recent studies have focused on specific members of insect larval gut microbiota in plastic degradation, but the impact of plastics on the overall gut microbial community remains unknown. This study examined the gut microbial composition of Tenebrio molitor (PS degrader) and Plodia interpunctella (PE degrader) larvae in control and plastic-fed groups. The results showed significant changes in microbial abundance in Plodia interpunctella fed with PE, but no significant changes in Tenebrio molitor fed with PS, suggesting different mechanisms involved in plastic degradation.

Summary: Marine ingredients are important for aquaculture and livestock feeds, but detailed information on their environmental impact is limited. A Life Cycle Inventory was compiled to allow for Life Cycle Assessments of marine ingredients, but there are still data gaps that need to be filled. An LCA demonstrated that marine ingredients have variable impacts, mostly depending on the fuel intensity of the fishery they are sourced from.

Summary: Woodchip bioreactors are effective in removing nitrate from aquaculture effluents, with microbial communities including sulfate reducing bacteria (SRB) and sulfate oxidizing bacteria (SOB) playing crucial roles. The conditions within the bioreactors shape the microbial communities, with similar design and operational settings leading to similar functions. Autotrophic denitrifiers can significantly contribute to H2S consumption and nitrate removal in woodchip bioreactors, improving their overall environmental benefit.

Summary: The establishment of early-life gut microbiota is crucial for fish development and health. Rearing fish larvae in recirculating aquaculture systems (RAS) improves survival compared to flow-through systems (FTS), and dietary probiotic supplementation modulates gut bacterial composition, promoting beneficial bacteria presence.

Summary: Ocean acidification can affect marine molluscs, but transgenerational plasticity may mitigate some effects. This study investigated how the microbiome can be influenced by transgenerational exposure to ocean acidification in Sydney Rock oysters. The results showed that parental exposure to elevated PCO2 altered the bacterial community composition in both eggs and larvae, with certain Rhodobacteraceae ASVs increasing or decreasing in abundance. These findings suggest that the transfer of maternal microbiomes to larvae is affected by exposure to ocean acidification and may contribute to transgenerational plasticity.

Summary: Developmental programs in animals not only shape their forms, but also equip them with the ability to sense and adapt to the microbial world they evolved within. Studies in human, mouse, zebrafish and Drosophila demonstrate the significant impact of microbiota on gut development and its communication with the nervous system, which has important implications for human and animal health.

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.
