It is very convenient for the fish-shape ponds and fish culture. It can better solve the green and fine feed of fish, tap the potential of fishery production, and increase economic efficiency. In general, freshly-recovered ziggurat ponds can produce up to 400-450 kilograms of fish per year, and they can break through the 500 kilograms per year. Its technical points are:
I. Excavation Ponds The zigging-shaped pond consists of three parts: pool ridge, fish ditch, and platform, each occupying an area of ​​1/3. The pool building is on the periphery, the fish ditch is centered and the platform is included. The width of the fish ditch is determined by the excavation area. The ditch bottom is 2 meters away from the platform, and the platform is 2.5 meters lower than the pool pool, and the effective water depth is 3.5-4 meters. When excavating fish ditch, the excavated soil is made into a pool of 1:2 slope, and the platform is leveled up into fields, and rice, big wheat, etc. can be grown as fine feed.
Second, the fish-feeding fish-shaped ponds are deep in the fish ditch, high in pond volume, large in water storage capacity, and they can produce green and fine feeds themselves, and they can be used in high-quality, multi-level and multi-species quality fish species. Specific distribution ratio: 80-100 per mu of grass carp size 150-250 grams, 60-80 perch 40-50 grams, 300-400 per carp 25-30 grams, 100-80 grams per carp-100. 150 tails, 50-60 tails of 80-100 grams of carp. The delivery time is appropriate for the first and the middle of January.
Third, the clever species of feed can be planted in the pond on the Sudan grass, from the middle of May, can be harvested every day for fresh feed, and continued until September. In early May, paddy rice can be planted on the platform. After harvesting of rice and sudan grass in early August, full base ryegrass can be planted on oysters and platforms, and harvesting can be used for 40-50 days. The spring began to grow again in the following year and was still harvested every day. It was continued until the end of March and the beginning of April.
Fourth, a reasonable feeding bait should be based on the season, water quality, weather and fish feeding conditions. The fodder was eaten on the same day and the condiment was eaten in 1.5-2 hours. The leftover grasses should be removed on the evening of the day to prevent rot from damaging water quality, which will help prevent fish diseases and ensure that fish eat fresh, eat enough, and grow fast.
5. Appropriately top-dressing high-temperature weather should be applied sparingly, with less application, and less rain or sultry days should be applied or not applied. Organic manure is generally applied once every 10-15 days, each time, 75-100 kilograms per acre. In the high temperature season, fertilizer is added every 6-8 days. Urea 0.8-1 kilograms of urea and 1.5-2 kilograms of phosphate fertilizer are used respectively. After the water spilled over the entire pond.
6. Regulation of water quality From January to April, the water temperature is low, the individual fish is small, and the feeding capacity is weak. The pond water level can be reduced to the fish ditch so that the fish can be kept in the ditch. From May to July, the water temperature can increase every 10 months. - The new water should be injected once every 15 days, every time 20-30 cm deep, try to maintain a higher water level in the pond; from 8 to 10 months, the individual fishes will increase significantly. The water level must be further increased to expand the water space and facilitate the fish activities. Jianchang speed fertilizer.
VII. Prevention of fish disease Symptom-shaped pond fish prone to enteritis disease, gill disease, etc., can take specific prevention-based measures: First, when the adult fish out of pond dry pond, with lime 60-75 kilograms per mu for pond disinfection , to kill wild fish and pathogens; Second, 1.5-2 kg per mu bleaching or 12.5-15 kg of lime Latang, once every 7-10 days, 3 times in succession, repeated intervals of 15-20 days; From the beginning of April, 0.25-0.4 kilograms of bleaching powder was sprayed on the food field per mu, once a month for four to five consecutive times.
VIII. Fractional fishing This is an important measure to obtain high yield and high efficiency in fish farming in a type-shaped pond. Fishing should be carried out 6-8 times throughout the year. The first time the fishing is mainly used to check the growth of the fish. After every 20 days or so, it will be caught once. First catch the carp and carp (June-August) and then catch grass carp ( August-September) In October, when clear ponds were used to catch bottom fish such as cockroaches and clams, "fishing, fishing, and harvesting were carried out." In this way, commercial fish out of the pool have large specifications and good economic returns.
