Problems solved by technology

[0003] Due to the carnivorous nature of catfish, the existing breeding technology is easy to cause diseases and affect the growth and development of catfish. In severe cases, large areas of death will occur, causing economic losses to farmers. Focus on stocking some beneficial organisms, resulting in an increase in feed costs

Embodiment Construction

[0012] A kind of culture method of catfish:

[0013] Selection and construction of the breeding pond: the area of ​​the breeding pond is set at 3 mu, the depth is 1.5m, aquatic plants are planted at the bottom of the pond, multiple aeration devices are installed in the breeding pond, floating plants are also stocked on the water surface, and the area is 10% of the area of ​​the breeding pond , set a layer of 25cm river mud at the bottom of the pool;

[0014] Release seedlings: Before releasing seedlings, sterilize the culture pond with quicklime for 10-15 days, clean the fry with 2ppm-potassium permanganate when releasing seedlings, stock 1,500 fish fry in each acre of culture pond, and stock them at the same time 2kg loach, 3kg snail, 100 silver carp;

[0015] Daily management: Feed once a day at 7 am and 4:30 pm, each feeding amount is 4% of the total weight of the fish in the breeding pond, and the pond water is replaced every 7 days during breeding, 1 / 4 each time, A ...

Abstract

The invention discloses a culture method for catfishes. The culture method comprises the following steps: before releasing seedling, comprehensively sterilizing and disinfecting a culture pond by quick lime with 10-15 days, clearing fish fries with 2ppm-5ppm potassium permanganate during seedling releasing, putting 1000-2000 fish fries into every mu of the culture pond, simultaneously putting 2-3kg of loaches, 3-5kg of snails and 100 catfishes into the pond; changing water in the pond once every 7-10 days during culture, changing 1 / 4-1 / 3 of the water in the pond at every time, completely changing the water which accounts for 90% of the total water amount in pond once each month, immediately treating once diseases are discovered, feeding food obtained by mixing traditional Chinese medicines once every 7 days. The culture method for catfishes disclosed by the invention emphasizes establishing an ecological system for water of the culture pond, some catfishes, snails and chubs are properly added during the culture of catfishes, so that not only can the water environment be improved, but also food, in addition to feed, can be provided for the catfishes, therefore, the culture cost of the culturist can be lowered; the water quality can be effectively improved by frequently changing water to prevent harmful bacteria from breeding; the traditional Chinese medicines can be added for strengthening the health of the catfishes and killing the bacteria in intestinal tracts of the catfishes.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a catfish culture. Background technique [0002] Catfish is rich in nutrients. Every 100 grams of fish meat contains 64.1 grams of water, 14.4 grams of protein, and contains a variety of minerals and trace elements. It is especially suitable for people who are weak and malnourished; [0003] Due to the carnivorous nature of catfish, the existing breeding technology is easy to cause diseases and affect the growth and development of catfish. In severe cases, large areas of death will occur, causing economic losses to farmers. Pay attention to stocking some beneficial organisms, resulting in an increase in feed costs. Contents of the invention [0004] The purpose of the invention is to provide a catfish breeding method which reduces the occurrence of diseases and reduces the cost of feed. [0005] In order to solve the problems referred to above, the technical scheme that the present...
