1.1 Pond conditions The pond area is 3-10 mu, which should not be too large or too small. If the area is too large, there is too much feeding of the summer flower, the bait fish is difficult to satisfy, and the individual growth is different. When the area is too small, the water quality changes quickly and it is difficult to control. The depth of the fish pond is 1.5-2m, especially for newly excavated ponds. The bottom of the pond is slightly inclined towards the outlet. Adequate water sources, convenient water intake and drainage, fresh water, no pollution, excellent rivers and lakes.
1.2 After the pond is ready for dry ponds from March to April each year, the ponds are cleared and the bottom sludge is cleared. The depth of the bottom of the pool is not more than 15cm. The bottom of the pool is exposed. The fish should be stored 10-15 days before the watering of the bait. The water should be drained 6-8cm. About 100kg of the quicklime should be used, and 5kg of bleaching powder (every other day) should be used to disinfect and disinfect the whole water. After adding water 60-80cm, when using water, use a 40-mesh sieve to strictly filter, to avoid mixed wild fish and predators into the pool. Disinfection 7-10 days later, after the test fish showed that the toxicity disappeared, the whole net was used to pull the net once, and the enemy fish pests in the catch pond were fed with 80-100 million bait fish feed per acre. Cultivated to 1.2-2cm for feeding in early summer flowers.
1.3 The breeding time for summer flowering and summer flowering is 6 months in the middle and middle of June. The stocking density is based on the breeding technique and the amount of feeding is determined by whether or not an aerator is equipped. The general density is 800-1200 tails/mu. Acrocephalus larvae 1-2 days before stocking change half of the pool water, so that the water is fresh, reduce the fat, 5-7kg of salt per acre of water Quanchiposa to clarify the pool water.
1.4 The bait fish ponds supporting the pond-breeding fish feed for the Acrocephalus can not meet its growth needs. It is necessary to provide matching bait fish ponds, which can be matched with 1:2 (area ratio) of fish ponds and fish ponds. The bait fish cultivation pond has the same conditions as the conventional fingerling pond. The fish ponds must be sterilized by clear ponds, and the disinfection method is the same as that of the main tanks of the Anodontes.
