The Pyongyang Catfish Farm is boosting production by consolidating its material and technical foundations.
It has made strenuous efforts to reduce assorted feed consumption and put production processes on an automated and unmanned basis.
In the course of this, it further decreased the size of the ground materials for floating feed to raise the rate of digestibility of feed and growth of catfish, and developed a preventive treatment technique for remarkably lowering the death rate of catfish.
It also designed and built an active electric boiler to suit its specific conditions, thus reducing the power consumption by one-fifth, and remodelled the production facilities so that it can produce a sufficient amount of early-stage feed for fries in all seasons.
It waged a brisk mass-based technical innovation movement to raise the rate of the operation of catfish harvesters and feeders and established a new water management system conducive to optimizing fish breeding.
