Oxygen supply fine bubble system to reduce mortality of live fish storage in the hold.

Achieving increased income by optimizing oxygen supply in the hold to support the vitality of fish in live fish tanks and reduce oxygen consumption.

We propose Nakajima Bussan's fine bubble system to fishery operators who want to deliver caught fish to the port in a healthy condition. By combining a generation nozzle, pump, and oxygen supply equipment, we supply fine bubbles to the live fish tanks in the hold. This helps reduce weakening and mortality loss during storage by maintaining dissolved oxygen levels. In a case study in the Seto Inland Sea, it was reported that during the summer, when water temperatures approached 30°C, oxygen was supplied at a rate of 2 liters per minute, resulting in usage being less than one-third of the conventional amount. Additionally, there are examples of maintaining dissolved oxygen (DO) levels above 4 mg/L while accommodating approximately 100 kg of eel in one section of the hold. We can also consult on utilizing your existing pump for implementation and propose equipment configurations based on tank capacity, storage capacity, and piping conditions. 【Usage Scenarios】 - Storage of live fish in fishing vessel holds - Oxygen supply during high-density storage - Low oxygen countermeasures during summer 【Benefits of Implementation】 - Supports the maintenance of fish vitality - Reduces weakening and mortality loss due to oxygen deficiency - Contributes to the reduction of oxygen usage
