Shrimp new method - seep water shrimp
Last year, Xiazhen Township, Kenli County, Dongying City used the ponds developed in the previous few years under the agro-fishery development to explore a new way of raising shrimp, and conducted a salt-alkali soil seepage and shrimp culture experiment. Permeation of water and shrimps is based on the characteristics of high groundwater level and large salt content in saline-alkali land, using salt water exuded from ponds, and according to the growth and development needs of shrimp, adding fresh water to adjust the optimal salinity. In order to feed the people to test the risks, the township party committee has drawn seven cadres with good political quality and high cultural standards to undertake the test task, and hired professor Wang Kexing of Qingdao Ocean University as a technical advisor to show it to the masses and to carry the masses. In the test process, unified acquisition of seedlings, unified water supply, unified bait, unified drugs, unified oxygen, and took clearing pond fertilizer, scientific feeding, water quality regulation, disease prevention and other technical measures. From May 29 seedlings to September 25 harvest 130 days, the average length of shrimp 12 cm, 6 shrimp ponds with a total area of ​​42 acres, a total of more than 4630 kilograms of shrimp, the average yield of 110 kilograms, the most limited shrimp pond The yield per mu reached 163 kilograms. The total output value of 277,800 yuan, profit and tax of 138,900 yuan, the water seepage shrimp experiment was a complete success, its main advantages are as follows: First, the economic benefits, compared with the seawater shrimp farming, the output value per acre increased by about 4,800 yuan. Second, it has broadened the shrimp farming industry and has a lower risk. Over the years, shrimp farming has been at a low level, and production has been low and unstable. Water seepage and shrimp rearing can avoid the invasion of seawater and storm surges, reduce investment risks, and bring new hope to the shrimp industry. Zhao Fazheng, an academician of the Chinese Academy of Engineering, spoke highly of the inspection. Third, it has opened up new areas for the development of saline-alkali land, making it difficult to develop saline-alkali land, and conventional agricultural development will not be effective. Infiltration of water and shrimp farming is a unique way, and a new path of changing the advantages of resources into economic advantages has emerged. Fourth, it is an important measure for enriching the countryside and enriching the people. A farmer contracted a shrimp pond, with an annual net income of about 20,000 yuan, a property tax of 130,000 yuan per 1 million yuan in output value, and significant social and economic benefits.
