Abstract

The invention discloses a breeding method for loach through net cages. The breeding method includes the steps that the net cages are manufactured, wherein rectangular cage bodies are made of net cloth; the net cages are placed in a pond in lines and rows, the adjacent net cages in each line are fixed through timber piles, and the interval between two adjacent lines ranges from 40 cm to 80 cm; water hyacinth and water duckweed are planted in each net cage, loach fry are disinfected for 5-10 minutes through a 1.5%-3.5% saline solution, during first three months after the loach fry are placed, bait is fed, since the fourth month after the loach fry are placed, mixed feed is fed, the mixed feed is fed a time at 8-9 o'clock every morning and 5-6 o'clock every afternoon respectively, and the quantity of the mixed feed fed each time is 1%-5% of the weight of the loach fry in the net cages. The breeding method has the advantages that large-scale loach breeding is achieved, the loach can be easily caught, the survival rate and resistance of the loach are increased, and the probability that the loach is infected by parasites is reduced.

Description

technical field [0001] The invention relates to the field of breeding. More specifically, the present invention relates to a method for cultivating loach net cages. Background technique [0002] Loach, commonly known as loach, belongs to Cyprinidae, Loachidae, and Loach genus. It is a small freshwater fish widely distributed in my country and Southeast Asian countries. Loach meat is tender, delicious, rich in multivitamins, has certain medicinal effects, and is deeply concerned and welcomed by consumers. At present, the domestic demand for loach reaches 300,000-400,000 tons / year, and the price is 20-30 yuan / catties. The demand in foreign markets is strong. According to incomplete statistics, the annual demand for loach in Japan and South Korea is about 300,000 tons, and the average price of export to Japan and South Korea is more than 26-28 yuan / catties. It is also rapidly increasing, therefore, farming loach has a broad market and profit margins. [0003] At present, the...
