The so-called family pond fish farming refers to digging fish in front of the farmer's house, behind the house or in the courtyard, or using fishermen's pits, low-lying land and waste ponds near the farmer to trim fish ponds. The fish ponds in the family can be large or small, ranging from about one acre to less than one or two minutes. If it is the spring autumn catch, pits do not have to be deep, and a depth of about one meter is enough. However, if you want to grow more fish, the best depth is 2-3 meters. The shape of fish ponds in home ponds and ponds can be used as a reference to fish farming in ponds. However, if you want to cultivate fish in order to beautify the courtyard environment, then you can use it naturally or process it into various attractive shapes. When fishing, it will increase some difficulties, but because of the small water surface, it may be more convenient to take the method of water withdrawal. Although the fish farming in the family pit pond is relatively small, it also requires sufficient water supply, convenient water injection and drainage, good water quality, and strong water retention. In places where there are cave streams, fish can be digging beside the foothills, and the water in the mountain streams can be introduced into the farm pits. In dry and dry areas, well water can also be used to raise fish. However, it is best to dry well water in a sun bath and then feed it into a fish pond. The soil quality of fish farming pits requires strong water retention to ensure that the pits do not leak water. Leakage ponds must be tampered with. The best conditions are to use masonry or triple soil slope protection. The bottom of the pond can be used for siltation at the bottom. Family pond fish culture must be repaired once a year, it is best to drain water after the winter to eliminate excess silt at the bottom of the pond, leveling the bottom of the pond, plug the loopholes, strengthen the pond, clear channels, remove weeds on the shore, clear Tang disinfection. Qing Tong is generally more use of quicklime or bleach. The use of quick-lime clear ponds and dry and wet methods for clear ponds are performed when the pond water is discharged to a depth of only 6 to 10 cm. Each pond has 6 to 7.5 kilograms of quick lime. In the small pits at the bottom of the pond, after the lime dissolves and dissolves, the entire pool is spilled. The wet pond is a depth of one meter, and each pond is splashed with 12.5 to 15 kg of lime. No matter whether the dry ponds or the wet ponds have to be fished in the past 7-10 days of the ponds. If you use bleach to clear the pond, you can press one meter deep water, use 1.35 kg of bleaching powder (30% chlorine) per minute, stir well with water, and splash it in Quanchipi. Fish can be released within 3-5 days. Lime clear pond or bleaching pond clear pond, compared with the two, quick lime at the end of the cost, easy to solve, but the amount is large, the effect is not as good as bleaching powder, but the cost of using bleaching powder is relatively high, and it is not easy to solve in rural areas. If quicklime and bleaching agent are used together with the clear pond, the effect is even better. Normally the water depth is one meter, and 6.5-8 kilograms of quicklime and 0.65 kilograms of bleaching powder are available for each surface. After the water is mixed, the whole pool is splashed and the fish can be released after 10 days. . Regardless of which method is used to disinfect ponds, for the sake of caution, it is best to put a few test fishes before putting fish. If the test fish does not die after one day, fish can be released in large quantities. The disinfection of ponds and fish ponds is an important measure to ensure the healthy growth of fish, especially for pits where fish diseases have occurred. Family ponds and fish farming should strive to put fingerlings into the water after the beginning of spring. The north can be used later, but it is necessary to fight for early stocking so that the fish species can adapt to the environment as soon as possible and eat early to win the growth time. It is best to choose sunny days when putting fish to avoid frozen fish. In addition, in order to increase the effectiveness of fish farming in ponds, it is best to use 13-17 cm of fish species. The way of fish farming in pit ponds is divided into two kinds: single breeding and polyculture. Such as polyculture, the proportion of all kinds of fish should be appropriate, generally more grass in places to raise grass carp, with a certain number of chain, cockroach, cockroach, cockroach, cockroach, cockroach, tilapia, grass carp may account for half. If the fat source is relatively abundant, the puffer should be reared with squid and squid. The squid can account for half of the total amount and the squid can account for 10%. It can be used with a certain amount of grasses, oysters, blues, oysters, cockroaches, and tigers. Non-fish and so on. The number of family pots for fish rearing can be determined according to the condition of ponds and ponds and feed conditions. Generally, the fish species of 13-17 cm can be reared with 300-400 species per mu and the number of fish species can be increased from 600-800. The stocking of fish species can be carried out once at a time, in stages, catching and catching large and small, or they can be stocked several times, harvested in stages, and catch small fish, so as to maintain reasonable stocking densities and fully utilize water bodies. Fish listed. Family pond fish culture should always pay attention to fertilization and feeding, pit and fertilizer fertilization base fertilizer and top dressing two, for the newly open pit pond or sediment pit is not fat, should be applied before the fish fingering basal, preferably in After the disinfection of the clear pond, the fertilizer was spread over the bottom of the pond and the water was discharged into the pond after the sun exposure. The amount of fertilization can be determined according to the pond bottom sediment and the type of fertilizer. Generally, 500-600 kg of fertilizer can be applied per mu of water, and 750-1000 kg of fertilizer can be applied if green manure is applied. Fish ponds in addition to fertilization, but also feeding, feeding is best to do four decisions: namely: quality, to ensure that the feed is fresh and delicious, do not feed rotten degenerate feed, quantitative, concentrate material is based on the weight of the fish 2 -5% feeding, feed generally 0.5 kg of grass carp, 0.5 kg of grass a day feeding; time, generally feeding 1-2 times a day, preferably 8-9 once a morning, 3-4 pm once; positioning, Every day, insist on feeding in a fixed place, it is best to set up a feed station. The number and quantity of feedings each day must also be flexibly controlled according to weather conditions, water quality, and fish feeding conditions. Generally sunny days can be cast more, cloudy days less cast, the weather is sultry, fish do not cast when there is a floating head phenomenon; the water is thick, when the water quality is too fat, it should be less or not. Family pond fish management is important. It is necessary to regularly inspect the pond to observe the fish condition. It is best to observe the fish pond once every morning, middle and evening. In addition to paying attention to the fish's eating and drinking conditions and changes in water quality, observe whether there are floating heads. Phenomenon, usually in the early morning or hot weather, thunderstorms and sudden changes in temperature and just after applying fertilizer, but also to carefully observe. At the same time, we must also pay attention to frequent decontamination and weed control to keep the water in the ponds clean and the sanitation around the ponds and ponds, maintain a certain amount of water and water quality, properly add fresh water, drain old water, regularly inspect the fish, and find fish diseases. Timely treatment.
