From 1984 to 1986, we undertook the Pilot Project of High-yielding Pond Culture of Fish in CST. Among them, mu net production of 500 kg of farming technology model, after three consecutive years of first test, retest and verification, to achieve the expected yield requirements, and in 1987 to promote the city’s application. I. Materials and methods 1. Selection of experimental ponds: We chose three experimental ponds of three different types with an area of 30.26, including 1 rural pond, 7.26 mu, 1 rural pond, 8 mu, municipal authorities Hospital 1, 115 acres. 3 test ponds, perennial water depth of about 2 meters, a small amount of sludge, water quality is good, irrigation and drainage convenience, when the sun hanging, farmland around the test ponds,
