Method for disinfecting misgurnus anguillicaudatus artificial breeding pond

Abstract

The invention discloses a method for disinfecting a misgurnus anguillicaudatus artificial breeding pond, and relates to the field of aquaculture. The method comprises the steps: drying the pond for standby application after repairing and maintaining of the pond are finished, and 15 d before misgurnus anguillicaudatus seedlings are stocked, carrying out secondary disinfection on the dried pond with quicklime and a traditional Chinese medicine composition; at the first time, disinfecting with quicklime with the pond disinfection quicklime amount of 75kg-100kg / 667 m<2>, dissolving into a slurry, splashing the whole pool, and injecting water with the depth of 20 cm-30 cm after disinfecting for 3-5 days; and at the second time, disinfecting with the traditional Chinese medicine composition, decocting the traditional Chinese medicine composition with water, extracting effective ingredients to obtain a water extraction drug liquid, splashing the whole pool, and 24 hours later, additionally injecting new water into the pond, wherein the traditional Chinese medicine composition amount is 1-2kg / 667m<2>. The method for disinfecting the misgurnus anguillicaudatus artificial breeding pond is simple in operation, good in disinfection effect, and more thorough in disinfection through two times of disinfection; the traditional Chinese medicine composition not only can further achieve the purposes of disinfection and sterilization on the pond but also can sustainably supplement water to sterilize and eliminate parasites; and besides, the water extraction drug liquid of the traditional Chinese medicine composition can improve the water body environment, reduces quicklime-caused adverse effects on water, and makes the water quality to meet misgurnus anguillicaudatus breeding requirements.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a disinfection method for loach artificial breeding ponds. Background technique [0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor that restricts the efficiency of loach farming is that the growth rate of loach is slow, and the annual growth rate is difficult to reach more than 3 times; the feed utilization rate is extremely low, and the bait coefficient is generally between 4.0 and 6.0, and some even as high as 8.0, whi...
