Kim Jong Un first looked round the monument to the field guidance given by leader Kim Jong Il standing in the compound of the station.

He learned about how the station has implemented the instructions given by the leader, recalling that he gave an instruction on breeding in sea water sturgeon, etc. living in fresh water after acclimatizing them to it, having an insight into the fact that if some freshwater fishes live in sea, they look nice in color and become tastier.

At indoor pond No.1 he asked from where sturgeon fries the station gets and what is production cycle and quantity and to which units they are supplied.

It is the last instruction of Kim Jong Il to breed lots of tasty and nutritious sturgeon and send them to Okryu Restaurant, he said, urging the station to thoroughly implement Kim Jong Il's instruction.

Kim Jong Un looked at sea cucumber bred in outdoor fish pond of the station.

He was satisfied to learn that the station cut down by half the production cycle as compared with other countries by studying and rounding off sea cucumber culture method of Korean style.

After going round the station, he gave precious instructions which would serve as guidelines for improving and strengthening its business activities.

To make people get real benefits is as important as building the breeding station into a modern one and registering successes in fish culture and research into fish breeding, he noted, underscoring the need to properly choose the units to be provided with fishes on the basis of calculation of the production, arrange well aquatic products supplying bases having restaurants and shops in Pyongyang and put their operation on a normal footing.

He noted that if the issue of fish food urgently needed for fish culture is to be solved and business activities are to prove profitable, it is necessary to mass-produce high quality fishes including sturgeon and export them to foreign markets.

He called for scrupulously organizing the work for successfully producing processed caviar recognized as high quality food worldwide, in particular, to get profits.
