Summary: Marine aquaculture mitigates environmental problems and periphyton-based biofilters are a promising technology for water treatment. The hydrodynamics of the system affect the growth of periphyton biomass and its ability to remove nutrients and produce dissolved oxygen. Integration of periphyton biofilters in recirculating aquaculture systems preserves water and improves water quality for fish.

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: The intensive exploitation of sea cucumbers has led to depletion of several species. The research on aquaculture of these echinoderms is minimal in Europe, but native species in Portugal show potential for aquaculture. Controlling the reproductive cycle is crucial for successful rearing.

Summary: Membrane technology has great opportunities and challenges in the application of recirculating aquaculture systems. Microfiltration, ultrafiltration, or membrane bioreactors can improve water quality and reduce water consumption. In addition, membrane-based systems also have promising prospects in shrimp farming.

Summary: Despite limited understanding of economic feasibility, there is increasing investment and use of land-based recirculating aquaculture systems (RAS) for producing market-size Atlantic salmon. High incidence of early maturing fish is a profitable obstacle for this production method, therefore well-defined RAS-specific water temperature thresholds are needed to minimize early maturation.

Summary: Salinity has a significant impact on survival, growth, gametogenic development, and gonadal coloration of sea urchins. Rearing sea urchins at low salinity conditions (20 and 25 psu) negatively affects somatic and gonadal yield.

Summary: The study evaluated the performance of a Continuous Flow Granular Reactor (CFGR) for treating freshwater RAS stream during two consecutive dry seasons. The configuration with a mechanical stirrer and sieve showed the best results in terms of biomass retention and nitrogen removal, achieving granulation in 55 days with high removal percentages of ammonium and nitrite.

Summary: This study analyzed temporal changes in the microbiome associated with the intestine in Atlantic salmon during smolt production, finding a sharp decline in microbial diversity 1-week post-seawater transfer (SWT) followed by re-establishment with a different community structure after 4 weeks. Core microbial taxa were classified into three categories: omnipresent, salinity specific, and transient. Additionally, an increase in microbial richness in the water was observed, possibly due to a temporal increase in organic load, while dominance of Vibrionaceae was attributed to higher temperatures during RAS production.

Summary: In this study, electrocoagulation (EC) was used for the first time to increase the particle size of total suspended solids (TSS) in a recirculating aquaculture system (RAS), improving filtration efficiency without reducing pore size. A linkage control system was constructed, increasing removal efficiency for TSS, COD, ammonia, and nitrite in Litopenaeus vannamei RAS by 24.07%, 24.30%, 8.94%, and 1.39%, respectively. The system also resulted in an average energy consumption of 2.38 kWh/d and anode loss of 370 g/d.

Summary: Recirculating aquaculture systems (RAS) manage waste and nutrient recycling to make intensive fish production environmentally sustainable. This study investigated the dynamics of prokaryotic communities in relation to water parameters, finding that shifts in the community were modeled by factors such as salinity and pH. The research provides new knowledge essential for understanding microbial community balance in aquaculture and serves as a valuable tool for overall aquaculture system management.

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: In this study, electrocoagulation (EC) technology was used to improve the performance of Litopenaeus vannamei (L. vannamei) recirculating aquaculture system (RAS) and investigate the nitrogen migration law and recovery strategy. The findings showed that EC significantly enhanced nitrogen removal in RAS, and Chlorella vulgaris was effective in recovering waste nitrogen from the system.

Summary: This study compares the kinetics of cadmium remobilization and the amplitude of its transfers with different marine sediments. The results show that the process of cadmium re-dissolution is highly reproducible. The intensity of sediment resuspension impacts the amplitude of cadmium remobilization, potentially exceeding the maximum allowable cadmium concentration set by the European Union Water Framework Directive.

Summary: The influence of salinity on copper toxicity on sea urchin embryos was investigated in this study. Results showed acceptable levels of anomalies in a specific salinity range. The effect concentrations (EC50) of copper revealed increasing toxicity at increasing salinity, but inversely related between certain salinity ranges. This study enhanced our knowledge about optimal salinity ranges and the potential impact of climate change on sea urchin embryo development.
