Summary: Chemical autotrophic and mature treatments can maintain toxic nitrogen compounds at low levels without addition of carbohydrates, while the heterotrophic system showed higher levels of ammonia and nitrite during the rearing cycle. Both chemical autotrophic and mature treatments maintained water quality, especially nitrogen removal, at a constant level, indicating advantages in shrimp growth. Analysis of microbial communities showed higher protein proportions in the heterotrophic system compared to other treatments.

Summary: This experiment evaluated the growth performance of whiteleg shrimp and three halophytes in a marine aquaponic system under different stocking density ratios and C/N ratios. The results indicated that stocking density ratio had a significant impact on shrimp growth, while plants were influenced by both stocking density ratio and C/N ratio.

Summary: A novel heterotrophic nitrification and aerobic denitrification (HNAD) bacteria, Bacillus thuringiensis strain WXN-23, was isolated from husk feed filtrate of a pig farm. It could efficiently remove nitrogen in simulated wastewater, adapt to low C/N ratio conditions, and showed a nitrogen balance efficiency of 63.5% in the form of N-2. The most optimal conditions for total nitrogen removal were shaking speed of 126.89 r/min, C/N ratio of 5.91, temperature of 32.81. C, and pH value of 8.17. The nitrification-denitrification metabolic pathway under aerobic conditions was determined, and strain WXN-23 exhibited high removal efficiencies for TN, NH4+-N, NO3--N and NO2--N in wastewater treatment.

Summary: This study investigated the effects of two carbon sources (sugarcane bagasse and wheat flour) on the biofloc composition, bacterial abundance, and growth of whiteleg shrimp. The results showed that the biofloc treatments using wheat flour as a carbon source could compensate for the reduction in dietary protein levels and maintain higher zootechnical performance.

Summary: In shrimp farming using biofloc technology, the change in biofloc colors from green to brown reflects a shift from autotrophic to heterotrophic microbial community dominance. This study developed a standardized protocol using the microbial community color index (MCCI) to assess water quality in intensive marine shrimp farming. The MCCI was positively correlated with carbon, nitrogen, and phosphorus concentration in the bioflocs, and negatively correlated with water transparency and green values. This method lays the foundation for a practical tool for water quality evaluation in shrimp farming.

Summary: The indoor nursery systems for whiteleg shrimp production offer control and biosecurity, but the study found differences in water quality, growth performance, and production costs between the clean-water recirculating system, photo-heterotrophic system, and biofloc technology system. Density-dependent effects were observed in terms of growth performance at densities exceeding 1000 org/m3.

Summary: The study found that increasing the C/N ratio can enhance the HNAD performance of Acinetobacter junii ZHG-1, but the effect diminishes when the C/N ratio exceeds 30. Therefore, more research efforts should focus on the influence mechanism of different environmental factors on the HNAD process.

Summary: Heterotrophic nitrifying and aerobic denitrifying bacteria, such as Pseudomonas mendocina Y7, show promising potential for nitrogen removal in industrial wastewater with low C/N ratio. Strain Y7 significantly improves removal efficiency of NH4+-N and total nitrogen, coexists well with other microorganisms, and maintains highly efficient and steady nitrogen removal in continuous treatment system.

Summary: This paper develops an architecture for flying ad-hoc networks (FANETs) to enable monitoring of water quality in a shrimp farm. A reference architecture for implementing a cost-effective FANET based mobile sensing platform is developed, which utilizes the controlled mobility of the platform to increase the spatial monitoring resolution without extensive infrastructure deployment.

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.
