The officials and workers in its fish farming sector applied natural and artificial egg-collecting methods effectively to boost the fish production 1.2 times.

The Kaesong municipal breed-fish station built or rebuilt hatching facilities and introduced profitable fish farming methods to discharge much more fry than planned. It also established a gravity-fed water supply system to raise fish on a mass scale while taking a nutrient care of breed-fish.

Such progress has been made at other fish-farming units of the municipality.
