In 1991, we conducted a test of 2.5 to 2.7 cm catfish (fish back) fry directly into the pond nursery at the Dashahe Reservoir fish farm in Kaiping County, Guangdong Province. The experiment was carried out for 63 days. With the special feeding of the “Mingzhu” brand catfish fish fry we developed, we achieved a good result of a survival rate of 80.32% and an average weight of 27.78 grams. The test is summarized as follows. 1 Test fish Twenty-two thousand six hundred and sixty-six (60) fish of Forktail (fish back) were purchased back from the united state fish fry farm in Xinxing County, Guangdong Province on May 25, 1991, covering a total length of 2.5-2.7 cm. 2 Experimental pond area of 2.8 acres, 1.1 meters deep, irrigation and drainage convenience, direct water from the reservoir through the water into the pond, April 29, 1991 with
