In the mountainous inland area of Tochigi Prefecture, a system has been successfully developed for raising Tiger Pufferfish using low salinity environmental water and heat from thermal springs in place of seawater. The development of this system, employed at an on-land enclosed, circulating, mariculture facility, marks the first time Tiger Pufferfish have been successfully bred throughout their life cycle in Japan. The system is currently able to produce for shipment 25 tons of fish per year. In future, we hope to continue to make use of local resources, promote the use of reusable energy, and contribute to the revitalization of the region.
