Improvement in the growth rate of eels! Introducing a case study of the UFB generation device for aquaculture.
We would like to introduce a case study of the introduction of a UFB generation device for aquaculture to Dream Workers Co., Ltd., which engages in the wholesale import of eel fry. Eel fry were raised in a 1.5-ton tank. During the testing period, UFB was continuously circulated, and for 8 hours each day (4 hours in the morning and 4 hours in the evening), oxygenated water was circulated. The growth rate of the eels improved, water clarity increased, and water quality improvement effects were observed. Out of 200 eels raised, approximately 30 individuals (15%) grew to over 20 cm in size. 【Case Overview】 ■ Testing Cooperation: Dream Workers Co., Ltd. ■ Test Subject: Bicolor species ■ Terms - Continuous operation of UFB pump - Daily switch to UFB oxygenated water for 8 hours, with pump operation ■ Duration: 20 days from July 29, 2021, to August 17, 2021 ■ Evaluation: Observation of growth and size comparison with the control period *For more details, please refer to the PDF document or feel free to contact us.

Company information
"Ultrafine bubbles (UFB)" are utilized in various fields such as agriculture, fisheries, home appliances, medical care, various industries, and energy-related industries. "Fine bubbles" are classified into two types based on bubble size: micro-sized "microbubbles (Micro-Bubble: MB)" and nano-sized "ultrafine bubbles (Ultrafine-Bubble: UFB)" (previously referred to as "nanobubbles"). These bubbles not only differ in size but also possess various characteristics that are distinct from the millimeter-sized bubbles (millibubbles) commonly seen. Our developed UFB generation device, "Shibata Engine," adopted by major home appliance manufacturers, produces ultra-fine bubbles with a central diameter of 100 nm at high concentrations using a single pass at tap water pressure. It is supplied to various industries, including home appliances, showerheads, and cleaning devices, as well as agriculture and food processing. [Features] - Can be integrated into existing products, equipment, and piping, and can also be utilized as components. - Capable of producing functional water such as ozone, oxygen, carbon, hydrogen, and nitrogen through gas-liquid mixing. - Compact and lightweight, making it suitable for use as components in home appliances, various pumps, water supply systems, showers, etc. - Customizable according to pressure and flow rate.
