Technology of breeding Rana ornativentris draws people's attention
  The Sungjin Biotechnology Development Centre of the Three-Revolution Exhibition House has developed and introduced a technology of breeding Rana ornativentris, drawing the attention of many people.
  The development centre found out frogs of good stock in a number of regions including the city of Kaesong and North Hwanghae and Kangwon provinces and adopted advanced science and technology and thus succeeded in completing the half-artificial cultivation method with low cost in Korean style.
  It introduced the half-artificial cultivation method into the forests of 14 regions and units and built a base for producing three million young frogs a year.
  It is taking a practical step to help the cities and counties with forests breed Rana ornativentris by themselves.
