Before the popularization of the aquaculture feed, farmers used to use live feeds for KURUMA shrimp culture. It was not possible to raise KURUMA shrimps in the distant islands, are from the southern part of Kagoshima to Okinawa Island where the live feeds were hardly obtained. However, in 1975 we commercialized KURUMA shrimp feeds and distributed into the domestic market for the first time. As the shrimp feeds had not been in the market before then, the shrimp culture began to flourish in these regions, and production volumes increased.
Moreover, HIGASHIMARU contributed to the improvement of yellowtail farming. Till then, it caused marine pollution due to large amounts of live feeds. With sufficient growth effect and low cost, our successful development of the fish feeds initiated reformation of yellowtail culture.

Our aquaculture feeds have a quality advantage in terms of stability compared with live feeds, and are easy to store, handle and transport. Of course, easy to use feeding is one of the great merits. Our mixed feeds are more effective to prevent from degrading the breeding water quality.
Furthermore, HIGASHIMARU is repeatedly undertaking various R & D projects with regard to improving the quality and higher added-value of our mixed feeds. We have generated our products with more advanced growth effect, survival & feed efficiency in comparison with those of competitor’s products. We have had such a profound influence on the aquaculture industry. Some people call it “HIGASHIMARU Effect”.
At present, our continued technology is for increasing added value- feeds to improve body color & fleshy substance of breeding fish, and disease resistance and suppression of parasites. Our products are exported to several overseas countries such as Vietnam, Bangladesh, India, Indonesia, Philippines and many more countries.
