ABSTRACT Eel fish species (Anguilla sp) is a fish commodity that has high economic value. Eel cultivation is still not widely controlled because of many factors that influence it, especially water quality conditions. Nanobubble technology is a technology that can maintain water quality, especially to increase oxygen in water. This study aimed to increase the production of eel fish through the nanobubble technology system and to improve the community's economic system in the fisheries sector. The writing method in this study used the literature study method. The results of the study explained that nanobubble technology was able to produce nano-sized air bubbles (70–200 nm) and rich in oxygen so that it could increase dissolved oxygen levels to 9 mg/L. Dissolved oxygen was needed to increase oxidation so that the nitrification process could take place so that it could eliminate ammonia levels in the water. In addition, the high oxygen content could increase metabolism so that it could increase the growth of eel fish. Dissolved oxygen concentration of water was a key control of habitat quality and a critical measure of water health for eel survival Therefore, with the nanobubble technology, it is expected to increase the production of eel fish. Advice for the public could be used nanobubble technology in the process of eel fish farming so that the production obtained could be maximized. Keywords: eel fish, nanobubble technology, oxygen ABSTRAK Ikan sidat (Anguilla sp) merupakan komoditas ikan yang memiliki nilai ekonomis yang tinggi. Budidaya ikan sidat masih belum banyak dikuasai karena banyak faktor yang mempengaruhinya, khususnya kondisi kualitas air. Teknologi nanobubble merupakan salah satu teknologi yang dapat menjaga kualitas air khususnya untuk meningkatkan oksigen dalam air. Studi ini bertujuan untuk meningkatkan produksi ikan sidat melalui sistem teknologi nanobubble guna meningkatkan sistem perekonomian masyarakat di bidang perikanan. Metode penulisan dalam studi ini menggunakan metode studi literatur. Hasil studi menjelaskan teknologi nanobubble mampu menghasilkan gelembung udara berukuran nano (70–200 nm) dan kaya akan oksigen sehingga dapat meningkatkan kadar oksigen terlarut menjadi 9 mg/L. Oksigen terlarut dibutuhkan untuk meningkatkan oksidasi agar proses nitrifikasi dapat berlangsung sehingga dapat menghilangkan kadar amonia di
