The Sosong Loach Soup House of the Sosong District Restaurant in Pyongyang serves customers using distinctively-designed fish ponds.
“A few years ago, most of our employees thought it was impossible to do fish farming in a small area. But after seeing other units benefiting from fish farming everywhere, we built a fish farm which is highly profitable as compared to the area in cooperation with experts of different units,” said chief of the eatery Kang Un Ha.
They mainly farm loach and raise carp, red carp and goldfish as well.
It is noteworthy that they use the surrounding unoccupied ground effectively as fish ponds.
The spaces on both sides of the building are roofed with plastic sheets and there are five fish ponds covered with double sheets inside.
They say this enables them to ensure necessary water temperature for fish farming all the year round.
Around the ponds there are over 200 flower pots for purifying air, which supply enough oxygen for fish farming.
They pump up underground water from the depth of 30 metres to constantly fill the water tank in the outside.
They increase the fattening rate of fish with assorted feeds made of different kinds of by-products from catering service and rice bran, shell, chrysalis and particularly use Azolla filiculoides to feed loach.
The survival rate of loach grown in the spawning pond is over 80 percent.
The house normally keeps dozens of kilograms of loach every day.
It serves over 30 kinds of dishes with the fish.
Especially popular ones are loach soup, fried loach with broiled mushroom, broiled loach and Lentinus edodes and broiled loach and green pepper. Women and children particularly like fried loach covered with crumbs which is prepared by frying seasoned loach covered with flour, beaten egg and crumbs.
According to employee Kang Chun Hyang, the house monthly supplies its employees with the loach produced by itself and sends it to several catering service facilities in Sosong District.
The loach soup made at the Sosong Loach Soup House was registered as national intangible cultural heritage element of the DPRK No. 79 and received many certificates at different loach cooking contests.
