Method for breeding paramisgurnus dabryanus fries

Abstract

The invention provides a method for breeding paramisgurnus dabryanus fries. The method comprises the following steps of: 1, building a breeding pond, namely building a cement pond with five smooth faces and an area of 60 to 100 square meters; 2, preparing breeding water, namely preparing the breeding water by mixing old pond water and fresh water in a volume ratio of 1:(0.5-1); 3, throwing fries: throwing 600,000 to 800,000 newly incubated fries in each 666.7 square meters; 4, opening mouth, wherein fresh milk is used as initial feed; 5, feeding, wherein tubificidae is used as breeding feed; 6, breeding, wherein because of high-quality water and feed with rich nutrition, paramisgurnus dabryanus fries can quickly grow up; 7, preventing insects, wherein green wide-spectrum insecticides are used for preventing insect damage; and 8, obtaining grown paramisgurnus dabryanus fries, wherein after 20 to 30 days, the paramisgurnus dabryanus fries are grown to be 3 to 4cm long, and at that time, the paramisgurnus dabryanus fries can be transferred to an adult paramisgurnus dabryanus breeding pond for breeding. When the method is applied to the breeding of the paramisgurnus dabryanus fries, the paramisgurnus dabryanus fries are high in survival rate and can be produced in batches.

Description

Technical field: [0001] The invention relates to a method for cultivating fish fry, in particular to a method for cultivating paraloach. Background technique: [0002] At present, there are two ways to cultivate the seedlings of Paraloach. The first way is the two-stage cultivation method, that is, put the water flower in a small cement pool, cultivate it with egg yolk for 2 to 3 days, and transfer it to the seedling after the food intake is normal. The cultivation pond continues to cultivate. The disadvantage of this method is that the water body is small and the water quality is unstable. Natural bait cannot be formed in the small cement pond. The second way is to adopt fertilizer and water cultivation, that is, water flowers are directly put into the pond of fertilization and cultivated, but there are two main problems in this method, the one is that the water quality of the fertilizer pond is not easy to control, and it is easy to cause the death of loach seedlings du...

Problems solved by technology

[0002] At present, there are two ways to cultivate the seedlings of Paraloach chinensis. The first way is the two-stage cultivation method. Egg yolks are cultivated for 2 to 3 days. After the food intake is normal, they are transferred to the seed cultivation pond to continue cultivation. The disadvantage of this method is that the water body is small and the water quality is unstable. Natural bait cannot be formed in the small cement pond. Influence

The second way is to adopt fertilizer and water cultivation, that is, water flowers are directly put into the pond of fertilization and cultivated, but there are two main problems in this method, the one is that the water quality of the fertilizer pond is not easy to control, and it is easy to cause the death of loach seedlings due to hypoxia; It is a harmful organism in the fertilizer pond, especially cladocera, which will harm loach seedlings

The low survival rate of seed cultivation has become the main bottleneck restricting the large-scale cultivation of adult loach, resulting in the scarcity of artificially cultured seed, high prices, and led to predatory fishing of wild seed
