In order to solve this contradiction, we experimented in paddy field to cultivate large-scale species of fish in Luotian Township in 1984. The results show that the use of paddy cultivation of fish species is an effective way to solve the current shortage of fish species. First, the test after 1, the experimental field to prepare the experimental field Select the southern mountainous areas in the county, easy access to water, fertilizer close to the two hills rice fields, with a total area of ​​2.93 acres. One of the mound is a fish farming area, an area of ​​1.43 acres; a hill for the control field, an area of ​​1.5
