At the side of Gaoyou Lake, many farmers purse squid and obtain better economic benefits. In places with similar conditions in Hunan Province, we can learn from them. The water level of the selected site is not too big, the water depth is 2 to 4 meters, the wind and waves are small, the plants are few, the water body flows slightly (the volume of water exchange is larger), and the area of ​​the fence depends on the water area and economic conditions, ranging from 20 to 100 acres. . The fence area is elliptical and intersects with the water at about 30 degrees. Seine nets are made of polyethylene with mesh netting and the net is 6 meters high. Nets usually 1 meter above the water surface. At the bottom, the net is fixed in the mud with stones. Use nets more than 10 cm in diameter to support the nets. Fish species stocking large-size carp, generally 0.25 to 0.5 kg per tail, stocking 10 to 20 kg per acre. If the market price is good from July to September, it is also possible to increase the stocking size and stocking amount and start to catch some from July to September. Stocking time is from January to March. When stocking, sterilize with saline or potassium permanganate solution. Should not put the carp, because of their sex, flooding when the hiding water, good jump, escape serious, and its cheap. If there are many aquatic insects and miscellaneous fish in the water body, you can match some carnivorous fish that have a smaller body weight than the eel, such as black tadpoles, big-mouthed oysters, and squid. When used with snails, it can be used with herring Management generally installs the fence and fixes the support bamboo when it is dry. It is usually necessary to prepare a boat to inspect the seine nets to prevent breakages and loopholes and replace the bamboos in time. Raise your nets when you rise. Prevent motor boats or buffalo from entering the fenced area at night. During the flood season, piles should be piled up in the area surrounding the fence to prevent large furniture and trees from breaking through the fence. The efficiency is based on a certain height of 110 acres of fences. In early 2006, 1100 kilograms of carp fingerlings were stocked, which was 6,600 yuan. The current management cost was 3,000 yuan, and the depreciation of the purse seized was 5,000 yuan. The total cost was 14,600 yuan. According to the author's understanding, in recent years, boiled fish heads, fish head tofu soup and other dishes have become popular with consumers. Carp, especially carp more than 1.5 kilograms, is worth more. However, if they are farmed in ponds, they need to spend a lot of money and manpower to put in compound feed, livestock and poultry manure, and chemical fertilizers (the cost of these feeds accounts for 70% of the farming cost). They must open aerators, and such raised fish should have a muddy taste or “keroseneâ€. taste".

If the area around the fence area is farmland and forests, insect traps can be installed above the fence area. In the nights from May to October when insects are energized, the insects are powered by fish for feeding.
In January 2007, a total of 9,526 kilograms of carp were caught and 800 kilograms of miscellaneous fish were sold, for a total of 68,200 yuan. The balance of payments was net profit of 53,600 yuan.
On the other hand, due to the development of agriculture and animal husbandry, many lakes and rivers already have the nutrient characteristics of medium-nutrient water bodies. There are abundant plankton in water bodies, plus micro-flow of water. It can ingest plenty of plankton and organic debris in the water (it is not necessary to manually feed the food). This approach is similar to the wild culture method, the fish taste delicious. The cost of aquaculture is particularly low due to only the species and fence, and bamboo. If the fence around the shore raises ducks, plankton and wild fish can be increased, and management can be carried out, which can also improve efficiency.
In addition, from an ecological point of view, squid farming in medium-nutrient waters (lakes or rivers) can prevent the eutrophication of water bodies and turn them into stench water, prevent endogenous pollution of water bodies, and achieve ecological benignity.
