The basic conditions for selecting suitable surface water must ensure that the area is more than two mu, the water depth is more than two meters, the water source is adequate and non-polluting, and the water quality is good. The bottom requires strong water retention and no leakage. We must do a good job of dredging and disinfection, remove some of the deposited sludge, and improve the bottom material. In the 7 days to 10 days before the fish species are stocked, quicklime is used to disinfect the whole body with 75kg to 90kg of water per metre of water. Poor conditions of the water should be equipped with aerator or water extraction machinery.
Pay attention to reasonable stocking first, it is early to stocking time. General stocking before and after the beginning of spring, and the release of warm-water fish must also be in early May. The sunny weather should be selected during the restocking period to avoid freezing of fish species. The second is suitable for stocking. For fishing, the water should be stocked with large individuals, fast growing, and easy-to-fish species, such as carp, mackerel, squid, tilapia, freshwater white plover, small scales, and other species. Can also be based on local food and water conditions to determine the stocking species, rich in grassland can be the main grass carp, carp and other herbivorous fish; rich source of fertilizer can be the main carp, pupa, etc.; snails, crickets can be the main raising herring, Squid and so on. In addition, the stocking species requires no pollution and no pollution. Varieties that are self-supporting must be farmed and managed in accordance with the relevant pollution-free standards prescribed by the state, monitored from the pond to the table, and promote healthy breeding. Healthy breeding includes aquaculture facilities, seed breeding, stocking density, water quality treatment, bait quality, drug use, and aquaculture management. A reasonable, scientific, and advanced culture method should be used in the aquaculture operations to obtain good quality and yield. High, no pollution to the environment of fishing products. The species that belong to the out-of-order holdings must choose the channels for buying fish to ensure that the purchased aquatic products are green and pollution-free. The third is a moderate amount of stocking. According to the conditions of the surface water and the feed conditions, generally, each side of the water surface rearing weight of more than 250g fish species 800 to 1000 tail. The fourth is flexible stocking methods. Can take a full time, in stages fishing, catch large and stay small; also can be restocked several times, phased fishing, catch up small; can also be fixed by fishing, with the fish, to ensure that along with fishing, to catch Value-added. When stocking fish, they can be sterilized with 4% saline or 10ppm bleach for 5 minutes to 10 minutes.
Do a good job feeding fertilizer feeding should be fed compound feed. According to the habits of fish, wheat bran, rice bran, bean cake, sub-powder, distiller's grains, minerals, and vitamins are used to make a mixed feed. The average feeding amount per mu is about 1500 kg. At the same time, the cultivation of herbivorous fish such as ryegrass and Sudan grass is planted. The concentrate feed was fed twice a day and the feed amount was calculated from 2% to 5% of the total weight of the fish. The amount of green feed daily was fed with lkg per kg of fish. The best place for feeding is to set up a feed station. The feed requires high quality, fresh, delicious and nutritious, and do not feed moldy, nutrient-only feed.
Fertilization pay attention to the application of top-dressing, before the release of fish species, the water must be applied to basal. The amount of fertilizer can be determined according to the bottom quality and fertilizer, generally 400 kg ~ 600 kg of manure applied to the manure, spread all over the pool bottom. The top dressing must be enhanced during the growing season. Before May, the temperature is low, and it is necessary to focus on cultivating plankton. Fertilize once every two or three days. Each time, put 100 to 150 kg of artificial livestock and manure per acre. After 5 months, the temperature will rise gradually. Organic fertilizer can easily cause flooding. Apply inorganic fertilizers, top-dressing once a week, applying 3kg to 5kg of chemical fertilizer per acre.
Strictly strengthen management
1. Special management. First of all, we must step up on duty and tour the pond day and night. Each morning, evening and midnight, the ponds are surveyed once to observe the water quality, fish feeding and floating heads, especially in the morning and summer, hot and humid days, before and after thunderstorms, sudden changes in temperature or when applying fertilizers. Second, regulate water quality. When the water quality becomes rich, properly drain the old water and inject new water. Change the water two or three times per month. Add 10 cm to 20 cm of water each time. Maintain the proper transparency and water color. Pay attention to the temperature difference when changing the water. Contaminated water and wild debris enter the pool. Diligently do breeding log. Create a special diary and register in detail the water temperature and the number of fish species in stock, fishing, and death to determine the number of feeding and refilling fish species. Finally, it is necessary to prevent theft. Prevent human theft, waterfowl and other animals from stealing fish.
2. Prevent fish diseases. The surface of the water for fishing is due to the quality of the bait and the condition of the fish. Fish disease may occur more than other culture methods, so it should be prevention-based. Normally, drugs are regularly used to prevent fish diseases. Each half a month, mu shall be splashed with lime of water l0kg or 0.7ppm of copper sulphate in water. At the same time, bleaching powder or copper sulphate or ferrous sulphate drugs shall be placed on the bait stage of fish to disinfect the food field. . You can also use baits for internal control of fish diseases. Occurrence of fish diseases requires professional and technical personnel to correctly diagnose and prescribe the right medicine.
Grasp business skills
1. Highlight the "famous" features, and constantly improve the quality of fishing species. Fishing is the core of fishing. In accordance with the preferences of anglers, the larger the specifications, the more popular the same variety; the better the variety, the better the variety. For anglers, in addition to enjoying fishing pleasure, fishing products are ultimately eaten or given away. For example, expensive fish, famous fish, conventional fish, and regular fish have natural nutrition and taste. Some famous aquatic products such as high-quality squid, stingray, tilapia, freshwater whitefish, and bigmouth bass or special aquatic products such as soft-shelled turtles and turtles not only have bright colors and beautiful shapes, but also have high nutritional value and are easy to fish. Of course, they will suffer Anglers love it.
2. To highlight the "green" features and to achieve pollution-free varieties of fishing. In the current "green revolution" storm, green is the trump card for all agricultural products. Natural, non-toxic, non-pollution, non-drug-free, non-polluted aquatic products are most popular among anglers. Fishing supplies must eventually be eaten. Of course, we must pay attention to the safety of food. Therefore, the fishing operators must lay a green card, comply with the consumer demand for food safety, so that their fishing species to achieve pollution-free. This requires that the operator can no longer hold the mentality of purchasing low-quality aquatic products at low prices for fishing and obtaining profits.
3. Highlight the characteristics of “playing†and comprehensively improve the quality of fishing. Fishing itself is a kind of amusement activity, which not only allows people to enjoy leisure pleasure but also meet people's sports needs. In specific practices, all localities should rely on local resource advantages to flexibly play this brand of pleasure and drive the development of the fishing industry. The fishing industry can be combined with local tourism, fishing industry can be combined with water sports. In addition, various forms of fishing competitions can be held to match friends, to promote the fishing industry, or to start more A variety of tourism projects featuring fishing villages and fishing villages will improve the benefits of the fishing industry and related service industries.
4. Highlight the "service" features and create a good environment for fishing development. The efficiency of fishing industry is inseparable from the advantages and disadvantages of fishing services. The fishing service includes the transformation of the road and environment for the fishing pool, the construction of fishing water infrastructure, the supply of fishing tackle, the announcement of variety and price information, catering services and even entertainment services, as well as the construction of fishing platforms, fishing tackle and fishing baits, and self promotion. The business features, ready for tea and meals. Playing a "service" card can also lead oneself among many business households and win in the increasingly fierce market competition.
