Problems solved by technology

[0002] In recent years, the yield per unit area of ​​the main ponds where the yellow catfish is mainly raised has been greatly improved. However, in the pursuit of high-yield and high-efficiency farming, a large amount of exogenous substances such as feed are used, which often causes problems such as deterioration of water quality and eutrophication of the water body, thus affecting the yellow catfish. Catfish growth and quality, and even frequent disease

Embodiment 1

[0021] A method for cultivating yellow catfish in environmentally friendly ponds, comprising the steps of:

[0022] 1. Selection of test pool

[0023] The test was carried out in the aquatic breeding field of Wujin District, Changzhou City. Two ponds were selected. The ponds in the test group had an area of ​​(5 acres) and a water depth of 1.5-2.5m. The bottom of the pond was flat and the thickness of the silt was less than 20cm. Each pond is equipped with a 3kw aerator, and the ridge of the pond is compacted and watertight.

[0024] 2. Pond renovation

[0025] In mid-March, the dry pond was dredged and disinfected with quicklime. A small amount of water was injected after 1 week. The distance between rows and plants of Elodea planted was 5-6 meters, and the distance between rows and plants was 3 meters. At the same time, water hyacinths are planted around the water body according to 20% of the total area of ​​the water body, and are divided into four square shapes and evenl...

Abstract

The invention discloses an environment-friendly yellow catfish pond culture method which includes the following steps of: pond selecting; pond modifying; fingerling stocking; fodder preparing and throw-feeding; water quality regulation and control and daily management. Compared with the prior art, the environment-friendly yellow catfish pond culture method has the advantages that water quality deterioration and water eutrophication can be effectively restrained, fish disease occurrence rate and death rate can be reduced and medicine use can be reduced by popularizing and using the successfully researched environment-friendly yellow catfish pond culture method to culture yellow catfish; good economic benefit can be obtained, more importantly, the pond water quality can keep good constantly, scarcely any culture waste water is discharged, and the ecological benefit is obvious; the nutritional quality of high-quality agricultural products and the healthy and safe environmental quality can be well combined.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and more specifically relates to an environment-friendly pond culture method for yellow catfish. Background technique [0002] In recent years, the yield per unit area of ​​the main ponds where the yellow catfish is mainly raised has been greatly improved. However, in the pursuit of high-yield and high-efficiency farming, a large amount of exogenous substances such as feed are used, which often causes problems such as deterioration of water quality and eutrophication of the water body, thus affecting the yellow catfish. The growth and quality of catfish even make diseases occur frequently. [0003] Therefore, in order to promote the healthy and sustainable development of the yellow catfish farming industry, it is very necessary to promote and apply the environment-friendly farming model of yellow catfish. Contents of the invention [0004] The purpose of the present invention is to overcom...
