Hamhung University of Chemical Industry has developed a combined fish feed additive.

This additive comprehensively improves fattening and survival rate and immunity function at the same time.

A research group of the university selected plants with high protein content among hundreds of species of plants and solved important scientific and technological problems including raising the protein content of fish feed in a biological engineering way.

In the course of this, they confirmed the composition and mixing ratio of the additive including microbiological ferment, vitamin and amino acid and succeeded in the development of the additive by studying the manufacturing technologies of various functional additives and separating technology of amino acid.

The additive, whose proportion of domestic production is over 95 percent, costs less, but raises fish fattening rate.

Its introduction into catfish farming raised fattening rate by 20-30 percent and increased survival rate by 10-15 percent as against those when it is not used.

At present, its production process has been established at Hamhung University of Chemical Industry and the Hamhung Catfish Farm and it has been introduced into dozens of fish farms.
