Pond conditions: seedling cultivation to earthen pond is better, an area of ​​30-100 square meters is appropriate, pool depth 40-60 centimeters, the pool excavation fish slip, in order to facilitate its habitat and summer cold, pond pool bottom ramming, into, Drainage ports are set to block nets, 15-20 cm of silt layer is laid on the bottom of the pool, duckweed is put in the pool, covering an area of ​​about 1/4 of the total area.

Qingtang Pei water: In the first 10 days after the seedlings are planted in the lower pond, 20-30 kg of quick-lime water clear pond is used for disinfection. After disinfection 300-400 kilograms of decomposed human and animal manure were used as base fertilizer to control water, and the water was added to 30 cm. After the water turns green, the seedlings can be placed after 15-20 centimeters of transparency.

Seed stocking: The seedlings will eat on the 2nd day after they are filmed. They will be fed for 3-5 days. The body length will be about 7 mm. The yolk sac will disappear. The camp will be fed with exogenous nutrition and can swim freely. At this time, the fish can enter the breeding stage. . The stocking density of seedlings should be 800-1000 tails per acre, and the microfluidic conditions can be appropriately increased. Note that the same batch of seedlings of the same batch hatch size should be stocked in the same pool to ensure balanced seed growth and improved survival.

Feeding and management: The seedlings that have just been in the pond have strong selectivity for feed. Therefore, it is necessary to cultivate suitable feeds such as rotifers and small phytoplankton. After filtering with a standard sieve of 50 mesh, they are fed along the pool side and properly fed and cooked. Egg yolk, fish meal, milk powder, bean cakes and Other concentrates. When the seedlings reach 1 cm in length, they can take in food such as insects, insect larvae and organic debris. They can use boiled bran, bran, corn flour, wheat flour and other vegetable feedstuffs to mix minced fish, shrimp and snails. Animal feed such as quail meat is fed 3-4 times a day. At the same time, the proportion of formulated feed is gradually increased in the feed to gradually adapt to the artificial compound feed. Feed should be placed on a food table about 5 cm from the bottom of the pool. Do not cast it. The initial daily feeding amount was 2%-5% of the total weight of the seedlings and 8%-10% of the latter period. Mud fertilizer and fertilizer, should be timely recovery of fertilizer materials, can be applied chicken, duck manure and other organic fertilizer, immersed in water in a woven bag; can also be applied fertilizer, water temperature can be applied when the ammonium nitrate is low, the water temperature can be applied at a higher Urea. Water quality management should be done in a timely manner, new water should be added in time, and water quality should be adjusted. When feeding for more than one month, the seedlings are 3-4 cm in length, and they can be turned into aquaculture when they begin to drill mud habits.
