On April 12, Huang Zhongquan, a farmer in Huaihe Township, Suizhou, told reporters that he had contracted a 500-mu reservoir in the village this year and raised “fat head fishâ€. The fry had already gone to the lake because it was a “novice†and needed to understand the “fat head fish†breeding technique. In addition, he has a 400-500 mu dairy farm near the fish farm. He wants to use cow dung to make water. How do I do this? The reporter interviewed the fishery expert Cheng Xianli of Hubei Aquatic Technology Promotion Center about his problems. There is nothing special about the management of the “puffhead fish†breeding technology, which is mainly to maintain good water. Technical requirements are as follows: Transparency requirements 20 ~ 25cm. The standard of Shiji Fei is 200~500kg of human excrement or chicken feces after fermentation, or 500~1000kg of manure. Fertilizer application depends on water fertilization, when the transparency is greater than 25cm, Mushi organic fertilizer 10 ~ 50kg, or inorganic fertilizer urea (N fertilizer) 2.5kg, phosphate fertilizer 1kg, organic fertilizer and inorganic fertilizer can be used interchangeably. Water quality is adjusted once every 10 days, and water injection volume is 20 to 30cm. Although the husbandry and management are simple, they cannot be sloppy. The first is to establish breeding files. The second is to adhere to the inspection system, check whether the reservoir is damaged, whether there is any change in water quality, whether the fish has floating heads, and if problems are found, promptly remedy the problem. Check for dead fish, find dead fish, remove it immediately, check the cause of death, and take preventive measures. The third is to regularly regulate water quality to ensure the healthy growth of fish. The fourth is to pay attention to oxygen and oxygen. As for the use of cow dung for fertilizer, the technology is easy to grasp. Build a large septic tank, put cow dung, and add appropriate amount of quick lime. Now the weather is ready for fermentation after 7 days. It should be noted that don't cast too much at one time, and you have to put it down slowly.
