Micro/Nano Bubble Technology : Characteristics and Implications Biology Performance of Koi Cyprinus carpio in Recirculation Aquaculture System (RAS)

Abstract

Technology for aquaculture is growing with the high demand of fish. Micro / nano bubble is one of technology that is developed to increase dissolved oxygen in water. This technology is used to increase Koi fish production in high density via RAS. The purpose of this study was to determine the characteristics of micro / nano bubble technology and its effect on biology of koi fish (Cyprinus carpio). Lutor was used to introduce micro / nano bubble in the fish tank by using fish length (e.g. 7.49 ± 0.29 cm). This research used completely randomized design with one factor (fish density) and three replications. This factor was three densities of fish at 15 fish.60 L-1 (A), 30 fish.60 L -1 (B), and 45 fish. 60 L -1 (C). The result showed that there was the absolute length of each treatments was (0.52 ± 0.03a) cm for A, treatment B (0.36 ± 0.07ab) cm and C treatment (0.29 ± 0.08b) cm. The best treatment is A treatment (15 fish. 60 L -1) and different significant in statistic with C treatment (45 fish. 60 L-1) but not significant in statistic with B treatment (30 fish.­ 60 L -1).

Control ofVibrioparahaemolyticus(AHPND strain) and improvement of water quality using nanobubble technology

“…Sweet fish (Plecoglossus altivelis) and rainbow trout ( Oncorhynchus mykiss ) cultured in air NB treated water were reported by Ebina et al (2013) to have better growth than those cultured in untreated water. There are also reports of koi fish (Cyprinus carpio) and red seabream ( Pagrus major ) benefiting from aeration with micro NBs (Henry Kasmanhadi Saputra et al, 2018; Stander, 2018).…”

Assessment of Ozone Nanobubble Technology to Reduce Freshwater Algae

“…Tis study suggests that ozone macrobubbles, at a dose of 0.025 ppm, are sufcient to control algae in pond water, while nanobubbles might not be necessary and could add extra cost for the treatment. However, some farmers may want to have a nanobubbler for other reasons, such as to increase oxygenation [10][11][12]. In these circumstances, it would simply be a matter of switching the input gas from oxygen to ozone to control algal blooms.…”

“…Another new technology that may help reduce algal blooms is nanobubble technology. Nanobubble technology has been used for water treatment and to increase dissolved oxygen levels [10][11][12]. It has also been used to remove contaminants in sewage wastewater by focculation [13].…”

Directional Transport of Underwater Bubbles on Solid Substrates: Principles and Applications

“…The underwater bubble is one of the most common forms of gas in insoluble liquids and is crucial in extensive fields such as the chemical industry, − machinery, − biology, − and medicine. − Compared with a free bubble that typically floats spontaneously to the liquid surface and is easy to collapse due to buoyancy, the attaching bubble usually persists in the liquid bath and is much more stable. The attachment to the substrate can be detrimental or beneficial, contingent upon the practice.…”
