The research is a key scientific research project issued by Hunan Science and Technology Commission in 1982 during the “Sixth Five-Year Plan”. It is undertaken by Hunan Fisheries Research Institute and Changde County Fishing Ground. It focuses on the existing problems of fish farming in small and medium-sized reservoirs in Hunan Province. Starting from the investigation of lakes, taking the methods of increasing and breeding together, it identifies the changes of resources from 1982 to 1985 as planned, Reform of key technologies such as fish-stopping facilities, the lake fish production rose from 265 tons to 575.6 tons before trial, an increase of 1.17 times, yield increased from 16 kg per mu to 35 kg. One of ten thousand acres of Willow Lake reached 461 tons, yield 46 kg, four-year total output value of 2.521 million yuan, the cumulative total profit of 1.0541 million yuan.
