2. Pond Disinfection: Dry ponds were used. On January 2, 2005, 80 kg of lime were used in each pond to dissipate the whole pond. 3. Seed stocking: 5 days after the pond was sterilized, the water was filtered through a 80-mesh sieve. On January 8th, 2,700 g/tail of the red-eye trout species were put on 2,700 tails, and at the same time, 160 tails of catfish, 13-14 cm in length, were placed with 300 tails of silver carp at 50-100 g/tail. Fish were soaked in 4% saline solution for 10 minutes before stocking. On June 10, 40,000 young shrimps were placed. 4, feeding and management. Artificially formulated pellet feeds were fed in combination with green feed. The artificially formulated pellet feed uses the 5717 and 5172 sink feeds produced by Cargill, and uses feed No. 5171 the previous month and feed No. 5172 later. Feed 2 times a day, each time from 8:30 to 9:30 in the morning and from 3:30 to 4:30 in the afternoon. The amount of feeding is based on the degree of eyelid and eyelid tailings within 30 minutes, and is based on the weather, water quality, fish activity and actual food intake. Green feed uses a method of raising duckweed at the corner of the pond for feeding by red-eyed hawksbills. 5, water quality regulation. Adjust water quality timely so that the transparency of the pool is maintained at 25-30 cm. (1) Add new water. When the fish stocks are stocked, the water depth is about 1 meter, and new water is added once a week for 10-15 centimeters each time. By the end of June, the depth of the pool water reaches 2 meters. (2) Each month, the water surface of the mu shall be splashed with lime 20 kg of mash for 1 time, so that the pH of the pool water will be maintained between 7.5-8.5. (3) Appropriate topdressing and regular sprinkling of microbial preparations. (4) Turn on the aerator at a proper time, open the aerator for 2-3 hours in the sunny afternoon from June to September, turn on the aerator in the rainy days or the floating head of the fish until the floating head disappears.
