Summary: This study assesses the sustainability of lambari aquaculture in Brazil using the emergy synthesis method and proposes improvements. The results suggest that the current farming systems have low efficiency, but sustainability can be improved by increasing productivity, improving water source utilization, and modifying feed composition.

Summary: This study found high variation in microbial diversity and composition in black carp polyculture ponds during the culture period. Physicochemical parameters significantly shaped the microbial community composition, with temperature, dissolved oxygen, and pH strongly correlated to dominant genera. Monitoring water temperature and SD could help manage potential pathogenic bacteria in the future.

Summary: This study investigated the environmental eukaryotic and fungi communities in pond-cultured grass carp and koi carp, revealing significant differences in microbial diversity and community structures between the two carp species. The findings provide important insights into understanding the characteristics of environmental eukaryotic microorganisms and fungi in edible and ornamental carps.

Summary: The artificial breeding of freshwater crabs in China accounted for 45.69% of the total output in 2020. However, microplastics were found to widely exist in ponds due to the addition of meals and the aging and breakage of plastic tools. This study investigated the abundance and characteristics of microplastics in ponds and crabs, and found that microplastics were present in water, sediment, and inedible parts of crabs. The results showed that microplastics in crabs were positively correlated with body weight and negatively correlated with hepatopancreas index, indicating potential risks of microplastic ingestion for humans.

Summary: The study investigated seasonal profiles of main antibiotic resistance genes (ARGs) and bacteria in waters from three predominant freshwater aquaculture practices near Honghu Lake in China. Results showed that fish ponds had the highest absolute abundances of tested ARGs, while crayfish ponds and adjacent ditches had similar ARGs profiles. Some bacteria were predicted to carry different ARGs, indicating multi-antibiotic resistances. Environmental factors partially shaped the profiles of ARGs and bacteria composition.

Summary: This study evaluated the impact of climate change on fisheries in the Czech Republic by examining changes in water temperature and their effects on fish farming. A model was developed to calculate surface water temperature based on air temperature, and the results showed that there will be a sharp increase in temperature regimes, posing challenges to traditional forms of common carp farming. Adaptation measures will be necessary to mitigate the impact of rising water temperatures.

Summary: Probiotics have significant potential benefits for freshwater fish farming, including disease prevention, improved growth rates, and enhanced feed conversion. While there is variability in reported effects, overall, probiotics appear to offer a practical solution for sustainable freshwater aquaculture.

Summary: A central goal of aquatic science is to understand the ecological factors that promote harmful cyanobacterial blooms, especially in light of climate change. Acclimation of cyanobacteria to temperature changes significantly affects their growth and toxin production, which can in turn determine the frequency, severity, and harmful effects of cyanobacterial blooms in aquatic habitats.

Summary: This study used a cradle-to-farm Life Cycle Assessment to assess the potential environmental impacts of Macrobrachium rosenbergii farming in Malaysia. The study found that the farming phase had the largest impact on human carcinogenic toxicity and freshwater ecotoxicity. Overall, M. rosenbergii farming was found to have a low environmental impact, but further research on other aspects of sustainability is needed.

Summary: The research revealed significant variations in the distribution and diversity of anammox bacteria in RPAS, with majority belonging to the Brocadia cluster. The abundance of anammox bacteria ranged from 3.33 x 101 to 41.84 x 101 copies per ng of DNA in RPAS, impacted by environmental factors like temperature and nitrogen composition in water. This study provides valuable information for understanding anammox bacteria in RPAS and improving regulatory measures.

Summary: The accumulation and volatilization of Se by algae are influenced by environmental factors such as pH, lighting time, and initial Se concentration. This study found that algae accumulate and volatilize more Se under harsher conditions, and the volatilization rate can be much higher than previously estimated. Additionally, the accumulation and volatilization rates of Se by algae are negatively correlated with final pH, final OD, and residual Se in solution.

Summary: Cyanobacteria interfere with water quality through cyanotoxin production and bloom formation. Faster, sensitive, and specific tools are needed for risk assessment. PCR coupled with DNA sequencing can detect cyanobacteria and their potential toxicity. Sampling on seven waterbodies in Portugal showed that ecosystems with blooms and heat waves had high potential of cyanotoxins, while absence of blooms and heat waves lowered the risk. Other ecological variables may interfere with cyanotoxin synthesis. Additional cyanotoxins should be included in monitoring programs.

Summary: The research revealed that bacterial communities in shrimp pond sediments exhibit high diversity, with core bacterial communities closely related to the physicochemical properties of sediments. At the mesoscale level, the bacterial communities in shrimp pond sediments are driven by stochastic processes.

Summary: Ponds contribute less to aquaculture production in Ghana due to low adoption rates and small holdings. This study finds that factors such as gender, extension service, membership of farmer-based group, knowledge of pond aquaculture, fish price, and freehold land positively influence adoption and intensity, while the transition ecological zone of Ghana has a negative relationship. The study also suggests promoting extension contacts, pond farmers associations, and more management innovations to accelerate participation of more women and youth in pond aquaculture.
