Embodiment 1

[0026] A factory cultivation method for carp fish fingerlings, comprising the steps of:

[0027] (1) Disinfection of the pool: clean the pool, then use bleaching powder to disinfect (use 1 kg of bleaching powder to convert 50 kg of water, and sprinkle it in the whole pool), rinse it with water, and set it aside; the pool is an indoor cement pool, a fish pond The area is 80 square meters, and the water depth is 0.8-1 meter;

[0028] (2) Water flower stocking: hatch the fry for 2-3 days, and start stocking after the appearance of the waist point. The stocking density is 50,000 fish / cubic meter. At the same time, artificially hatched rotifers are fed. 1-1.5 cm, feeding small cladocera with a body length of 0.5-2 mm; the survival rate reaches 70%.

[0029] (3) Domestication: After the fry body grows to 3-3.5 cm, place the fry in the domestication pond for domestication. The domestication density is 1-15,000 fish / cubic meter. On the first 1-3 days, live fish are fed. Large Cladoc...

Embodiment 2

[0033] A factory cultivation method for carp fish fingerlings, comprising the steps of:

[0034] (1) Disinfection of the pool: the pool is cleaned, then disinfected using potassium permanganate (40-50 grams of potassium permanganate is used to dissolve 50 kilograms of water, and the whole pool is splashed), rinsed with water, and set aside; The pool is an indoor cement pool with an area of ​​100 square meters and a water depth of 0.8-1 meter;

[0035] (2) Water flower stocking: hatch the fry for 2-3 days, and start stocking after the appearance of the waist point. The stocking density is 50,000 fish / cubic meter. At the same time, artificially hatched rotifers are fed. 1-1.5 cm, feeding small cladocera with a body length of 0.5-2 mm; the survival rate is 68%.

[0036] (3) Domestication: After the fry body is 3-3.5 cm long, place the fry in the domestication pond for domestication. The domestication density is 15,000-18,000 fish / cubic meter. On the first 1-3 days, feed live fis...

Abstract

The invention relates to a method for industrialized cultivation of carp fish species. Firstly, the pool is cleaned and disinfected, and the fry are hatched for 2-3 days. After the waist point appears, they are stocked and fed with rotifers at the same time. 1.5 cm, feeding small cladocera; when the fry grow to 3-3.5 cm, they will be domesticated; Continue domestication in the sub-sieve domestication pond; the successful tame carp fry are placed in the successful domestication pond and continue to be fed. After the body length is greater than 10 cm, they are placed in the fingerling cultivation pond and continue to be cultivated to a body length of 20 cm. The method of the present invention is not affected by weather conditions, the conditions such as water quality and temperature are relatively stable and controllable, and there are few diseases, and feeding is carried out under artificial control conditions, and the survival rate of flowering is high and stable. The method of the present invention can greatly improve the The survival rate of almond fish species is improved, and the large-scale cultivation of almond fish species is realized.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a factory cultivation method for carp fish species. Background technique [0002] Elopichthys bambusa, commonly known as yellow catfish, pole fish, and water tiger, belongs to Cypriniformes, Cyprinidae, Leuciscinae, and Elopichthys taxonomically. It is widely distributed in the Yangtze River, Pearl River, Heilongjiang, Yellow River and various water systems along the eastern coast. It is an emerging famous and special breeding species with high economic value. Carp has many advantages such as fast growth, large individual, firm meat, delicious taste, high protein and fat content, low cholesterol content, etc., and is listed as a large and high-quality edible fish. [0003] Carnivorous carp is a ferocious carnivorous fish in the Cyprinidae family. It lives in the middle and upper layers of water bodies and is a semi-migratory fish in rivers and lakes. It lays eggs...
