Experience of culturing Pelteobagrus fulvidraco in rice field

First, the choice of rice fields. It requires convenient intake and drainage, adequate water source, good water quality and strong water retention. The area is generally 8-10 mu per piece.

Second, field engineering. Open and control the word "field" or "well", the ditch is 3-5 meters wide and 0.8-1 meters deep, the drainage channel is built, the inlet and outlet is sealed with a tight mesh, the base is tamped, and the ditch at the outlet of the outer ring is dug to 1.5 meters deep.

Third, stocking seedlings. Clear the pond with 50-100 kg of quicklime per mu 7-10 days before stocking. The next day, add 0.5-0.8 meters of fresh water. After clearing the pond and about 7 days before the seedlings were planted in the pond, 300-500 kg of rotten livestock and poultry manure was applied per mu. In general, there are 4000-5000 fry per mu and 500-1000 mixed culture per mu. Stocking from May to July.

Fourth, feeding and management. ⑴ bait feeding. If there are a large number of zooplankton in the water in the early stage, some minced fish, shrimp and artificial formula feed can be added appropriately, and if there are not many zooplankton, they can be fed at 5% of the fish's body weight, and the proportion can be appropriately reduced in the later stage. The appropriate feeding time in July, August and September is 9-10:00 and 4-5 p.m., and the daily feeding amount in the morning and afternoon accounts for 40% and 60% of the total daily feeding, respectively. Continuous overcast and rainy weather, the amount of feeding should be reduced appropriately. ⑵ management. The water depth of the pond under the seedlings is 0.5-0.8 meters, and the water is added gradually. The water depth is more than 1 meter in July, August and September, and the water quality management is the same as the routine. When rice diseases occur, low-toxic and high-efficiency pesticides should be used, spray method should be adopted, and fresh water should be injected in time after the use of pesticides.

Fifth, fishing. From December of that year to January of the following year, Pelteobagrus fulvidraco was caught in dry ponds, and Pelteobagrus fulvidraco, which was too small, was hoarded in another pond as a large fish species for the following year.
