Yanglinwei Town is a famous land of fish and rice. There are 30,000 mu of intensive fish ponds, fish lotus 1 10,000 mu, 30,000 mu of high-quality rice, 40,000 mu of high-quality cotton, 50,000 mu of high-quality oil, and 30,000 mu of high-quality pulp forest. 1 1 Aquatic products sell well all over the country. It is a national commodity grain and commodity cotton production base, a provincial aquatic product plate base and a major agricultural town in the city.
The whole town has newly built 2 1 km highway, basically realizing cement road for every village. The improvement of safe drinking water in 9 villages benefited 265,438+03 families, exceeding10,000 people. 900 new biogas digesters were built, and 150 households were renovated. 654.38 million camphor trees were added, benefiting 25 villages, and the land consolidation project for schistosomiasis control was completed with high quality17.6 million hectares. The whole town has developed the area of fish and soft-shelled turtle 1.5 million mu, registered trademark of "Trionyx sinensis in Carassius auratus Lake", crayfish culture reached 1 10,000 mu, eel culture in cages reached 5,000 mu, river crab culture reached 2,000 mu, and japonica rice cultivation reached 7,000 mu. In recent years, Yanglinwei Town has organized and mobilized fishermen to vigorously adjust the structure of aquatic products, completely breaking the traditional pattern of feeding "four big fish" in fish ponds, and boldly exploring the "fish-turtle interplanting" model. At present, the town has formed six efficient breeding bases along Pengyang Highway, Jieyang Highway, Caodong Lake, Carassius auratus Lake, Yanba Lake and Shezifan to interplant fish and turtles. This alone, the town's annual net income increased by 60 million yuan, and the per capita net income in rural areas increased by a net amount. In 800, Yanglinwei Town decided to take fish and turtle breeding as the number one project in the development of modern agriculture, pay close attention to the construction of the "Hundred Miles Wild Turtle Fish Economic Circle" in the town, and strive to make the fish and turtle breeding area in the town reach 50,000 mu, with a total of more than 5 million turtles, with an annual output value of more than 300 million yuan and an annual net income of more than 200 million yuan, so as to build the first turtle breeding town in Jingchu. At present, our town has been recognized as a pollution-free aquatic product breeding base by the Ministry of Agriculture, and 1 1 varieties such as Trionyx sinensis have been certified as pollution-free aquatic products, and "Trionyx sinensis in Carassius auratus Lake" has been approved for trademark registration.
The interplanting of fish and turtle conforms to the ecological principle, which can maintain the underwater gas balance, which is not only beneficial to the metabolism of fish, but also promotes the reproduction of plankton. When fish and soft-shelled turtle are interplanted, the metabolism of soft-shelled turtle will produce a lot of ammonia. Through the action of plankton on ammonia, the output of plankton is increased and the water quality is purified. At the same time, turtles can eat some fish and dead fish that swim slowly due to illness, which can prevent the spread of pathogens and reduce the occurrence of fish diseases. Healthy fish swim fast and will not be invaded by turtles. Soft-shelled turtles grow in fish ponds with stronger vitality than those raised in greenhouses, and the mortality rate is greatly reduced. The fish-turtle interplanting model has achieved the goal of harmony and health.
The economic benefits of the year when it was put into use were obvious. A turtle of about 300 grams can grow to 1000 grams in that year, and generally 50 turtles are put per mu. According to the price of 500g 40 yuan, the average output value per mu is 4,000 yuan. Excluding expenses, the average net income per mu is 2500 yuan, which is four times higher than that of the "four big fish" feeding once. Two years is a cycle, and the economic benefits are more considerable. A turtle weighing about 150g can grow to 500g in one year and 1000g in the next. Generally, the input per mu is 150 turtles. According to the price of 500g 40 yuan, the average annual output per mu is 6,000 yuan, and the average annual net income per mu is 3,000 yuan excluding expenses. The "Four Big Fish" and wild turtles were raised together, and the annual net income per mu of fish pond increased from 1.500 yuan to 4,500 yuan, and one mu of fish pond became three mu of fish pond.
