1, fish pond conditions. The bottom of the pond is required to have a sandy bottom, with less silt, a water depth of 2-3 meters, and an area of ​​1-3 acres. It is convenient for drainage and irrigation, no inflow of sewage, and a small amount of drowning water. A shallow ditch with a depth of 30-40 cm is also to be dug around the pool for the fishing of carp. 2, pond preparation and feed fish cultivation (1) bait fish 10-12 days before stocking, with lime clear pond. (2) Natural bait cultivation. In the 7 days before the stocking of fry (carp, silver carp, etc.), water is added to 60 cm, and about 150 kg of fertilizer is put into the water surface of each mu to cultivate zooplankton such as rotifers and Cladocera. (3) Cultivation of feed fish. 1 Feed Fish Variety and Stocking Density: Feed fish is generally white sea bass, squid, squid, etc., and the amount of mu fish is about 300,000. 2 Feed the fish into the previous day, add 10 centimeters of fresh water to make the water fresh and rich in natural food. After the fry is placed, it is not necessary to feed it immediately. Observe the density, constitution, growth rate and the number of red worms in the water every day until the number of red worms is reduced. When the fry are foraging around the pond, immediately use the thick slurry to “spout the beach†and Several times a day to check the situation of each feeding point, in the early feed to eat, add, in the later control feed fish specifications to be controlled. General stocks of 8-10 cm of salmon are stocked, and feed fish specifications should be controlled at about 3-4 cm. 3 Forage fish can also be put into some old loach, and the small loach that is produced can be used as a high-quality bait for trout. 4 The proportion of cod farming area and feed pond area is generally 1:3-4. 3. Stocking methods. 1 direct method: about 3 cm of fry under the pond, has been developed into commercial fish. 700-1200 tails per mu. 2 step-by-step method: After raising the fingerlings, raise them to 10 cm and stock them again, 650-800 tails per mu. 4. Feeding technology. 1 Feed supplement fish on a regular basis (1 to 3 days). When the amount of feed fish in the pool was sufficient, the fish ran out of bait on the bottom of the water, so the surface of the pond was only small and small. When listening, the sound of water produced by fish catching feed fish is small, and the time interval is large. If there is a shortage of feed fish in the pool, the carp feeds the feed fish to the water layer, so the water spray is large, the sound emitted is frequent, and the sound is loud. If you see a group of squid hunting for fish at the edge of the pool, it means that the feed fish in the pool have basically finished eating. 3 The palatability of feedstuffs for fish: The specifications are generally about 1/3 of the body length of the carp. When the specifications are not uniform, large-size feed fishes should be screened with a fish screen. 4, water quality management. 1 The quality of water must be kept at a standard of “fat, live, tender and cool†all year round. 2 Maintain the relative stability of the fish pond water level. 3 Install aerators to prevent catfish from anoxic floating heads.
