Summary: The globally distributed bacterium Streptococcus iniae is responsible for outbreaks of disease in economically important freshwater and marine fish species, but our understanding of its transmission and infection dynamics remains incomplete. This study found that S. iniae has the ability to form resilient biofilms, providing an effective mechanism for its persistence in the environment. Further research on controlling this pathogen is necessary.

Summary: Streptococcus iniae is a re-emerging bacterial pathogen in freshwater and marine aquaculture worldwide. Currently, in the United States, there are no commercial vaccines available for S. iniae, and autogenous vaccines have limited protection. Serial passage of S. iniae in the presence of rifampin may generate immunogenic live-attenuated vaccines that confer protection against heterologous strains.

Summary: Streptococcus iniae is an emerging zoonotic pathogen causing epizootics in reef fishes. A Multi Locus Sequence Typing (MLST) panel was developed using genomic data from isolates collected over 40 years in different countries. The study revealed at least two independent emergence events of S. iniae on Reunion Island and highlighted the pathogen's ecological flexibility and ability to infect multiple host species.

Summary: Lates calcarifer, also known as Barramundi or Asian seabass, is a highly productive fish species suitable for large-scale aquaculture. However, the dense populations in aquaculture settings increase the risk of infectious diseases, which negatively impact yield. Immunization of juveniles and development of new immunization agents are crucial for improving aquaculture efficiency and food security.

Summary: Artificial intelligence can assist in fish production and management decisions in recirculating aquaculture systems. However, the accuracy of machine learning models in this context is dependent on the quality of input images, which face challenges due to underwater conditions. This study explores the effect of various factors on model accuracy for fish detection under RAS production conditions.

Summary: In order to solve the nitrate accumulation in recirculating aquaculture system (RAS), this study aimed to provide organic carbon source, denitrifying bacteria, and microenvironment for denitrification. Denitrifying capsules were prepared and their morphology, microbial community, and nitrogen removal efficiency were investigated. The denitrifying capsules had a porous structure and showed good adaptability to environmental conditions. They exhibited high nitrate removal rates even at low solid-to-liquid ratios or low temperatures. The denitrification process of the capsules followed a zero-order reaction and the denitrification rate was calculated to be 109.0 mg N/L-capsule dot h. The capsules showed a high nitrate removal rate until the litchi powder was exhausted.

Summary: By cultivating tilapia in an air-tight tank of a recirculating aquaculture system, CO2 is produced for the growth of Scenedesmus armatus in photobioreactors. It was found that the CO2 concentrations in the tank were higher than in the atmosphere, and using the captured CO2 and nitrate from tilapia farm effluent enhanced algal biomass production. This study demonstrates the potential of repurposing CO2 from aquaculture systems to enhance algal cultivation.

Summary: The study found that 11 antibiotics were detected in RAS, with 11 detected in water samples and 12 in sediment samples, while no antibiotics were found in fish muscles and feed. TWPPs were effective in removing antibiotics from water. Antibiotic concentrations in RAS were lower than those in nearby open aquaculture ponds, indicating better removal efficiency of TWPPs.

Summary: Recirculating aquaculture systems (RAS) are promising for sustainable aquaculture development, but nitrogenous waste accumulation is a limitation. The anammox process shows potential for treating marine wastewater, with marine anammox bacteria Candidatus Scalindua as a promising candidate. However, anammox activity is affected by unknown compounds in RAS wastewater and/or sub-optimum trace elements content, and TE supplementation can help recover activity. Future studies need to identify the unknown factors and determine specific TE requirements for optimal RAS wastewater treatment by Candidatus Scalindua.

Summary: The discharge management of Recirculating Aquaculture Systems is crucial for the development of the aquaculture sector, as RAS do not naturally result in low nutrient emissions. Danish commercial trout farms have successfully adopted wetlands and woodchip bioreactors for effluent treatment. The novel "zero-discharge" RAS system in Denmark has shown promising results in reducing nutrient effluent levels and reusing water effectively.

Summary: This study aimed to improve the design of stormwater biofiltration systems for the removal of micropollutants and understand the role of micropollutant-degrading bacteria. The addition of granulated activated carbon to the filter media significantly enhanced the removal of atrazine, a model micropollutant, and accelerated its degradation. The prototype biofiltration system showed the potential for sustainable microbial remediation alongside the removal of stormwater macropollutants without compromising the overall removal performance.

Summary: The reuse of household greywater is increasing globally, however, wastewater and greywater treatment processes are not fully effective in removing all contaminants. The dynamics between emerging micropollutants and antibiotic resistance genes in greywater treatment systems are complex. More studies are needed to understand the fate and transport of emerging micropollutants, antimicrobial-resistant bacteria, and antibiotic resistance genes in microbial communities and soil properties.

Summary: Diaphorobacter strain DS2 degrades 3-nitrotoluene and 2-nitrotoluene via 3-nitrotoluene dioxygenase (3NTDO), but is not directly involved in the degradation of 2,4,6-trinitrotoluene (TNT). DS2 strain can grow using TNT as the sole carbon and nitrogen source. Ammonium chloride and succinate can enhance the degradation rate of TNT. TNT does not compete with 3NT degradation in the resting cell experiment.

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.
