Aquaponics is a sustainable aquaculture technology that integrates a recirculation aquaculture system with plant cultivation in one system. The aquaponic system can be a solution that can be used as an intensive fish farming system and increase fish farming production. However, intensive cultivation will cause dissolved oxygen concentration to decrease rapidly. It will affect the water's quality, so an aeration system is needed to maintain the balance of dissolved oxygen in the water. The difference in the use of aeration systems in aquaponic systems will certainly provide different water quality results. So, this study aims to determine the type of aeration system most effective for cultivation activities in the aquaponic system. The method used in this study is a descriptive exploration of various literature and research results that have been published, both from books, national journals, and international journals. Based on a comparison of the results of previous studies, it can be concluded that aeration technology with microbubble sizes such as MNB and FBs can increase oxygen higher and more stable than conventional and venturi aeration technologies. The application of MNB and FBs aeration technology can produce water quality with dissolved oxygen concentration >7 mg/L, reduce ammonia concentration to <0.01 mg/L, nitrate concentration to <0.6 mg/L, and phosphate concentration <0.3 mg/L, as well as reducing total solids to 16% and volatile solids to 32%.

Dissolved oxygen in aquaculture systems, including aquaponics systems, cannot be filled only by natural diffusion, so an artificial aeration system is needed. Suboptimal aeration levels not only affect metabolic activity, but also affect serum and fish blood performance (hematology). This study aims to evaluate the impact of the aeration system on the health and well-being of fish cultivated in an aquaponics system. The method used is by studying the literature related to the aeration system of fish farming carried out in the aquaponic system which is relevant to the keywords of aquaponic system, aeration system, fish health and hematology from various sources such as: Google Scholar, Elsevier, Springer and Research Gate. Based on the comparison of several studies, it can be concluded that the aquaponic system using an aeration system can improve fish health performance based on hematological parameters.

Catfish (Clarias gariepinus) is one of the leading aquaculture commodities in Indonesia, with a production volume reaching 1.01 million tons, accounting for approximately 15% of the national aquaculture output in 2020. The availability of high-quality fry is crucial for the sustainability of catfish farming. This study aims to evaluate the effect of high stocking densities on survival rate, condition factor, and size variation of catfish fry reared in UFBs-RAS. This research was conducted at PUI-PT Nano Powder Functional Universitas Padjadjaran (Jatinangor) from October to November 2023. The study tested catfish fry with lengths of 3–4 cm and weights of 1.2–1.4 g with four densities (10 fish/L, 15 fish/L, 20 fish/L, 25 fish/L). The results indicated that stocking density did not significantly affect the survival rate (P>0.05), but it did have a significant effect on length and weight variation (P<0.05). The condition factor did not show significant differences (P>0.05) between stocking density treatments. Overall, a density of 25 fish/L yielded the best performance within the UFBs-RAS. Therefore, this density is recommended as the optimal stocking rate for catfish fry rearing in this system. These findings suggest that the application of the UFBs-RAS system provides a strategic solution for the aquaculture industry to enhance the efficiency of catfish fry rearing at high stocking densities while maintaining optimal water quality and growth performance, thereby supporting productivity and sustainability in intensive aquaculture systems.
