Problems solved by technology

However, the traditional pond culture of fish is carried out at the cost of consuming a large amount of natural resources, that is to say, the occupation of land resources is increasing, the consumption of water resources is increasing, and the consumption of biological resources is increasing. , and during the breeding process, a large amount of organic matter such as residual bait, feces, corpses of dead organisms, and sediments in the aquaculture water body accumulat

Embodiment 1

[0052] A method for culturing carp, comprising the steps of:

[0053] (1) Fish pond cleaning: Select a pond with an area of ​​5 mu, a pond depth of 2.1 meters, and a silt thickness of 7 cm as a fish pond. 7 days before the fry enter the fish pond, 2600 kg of fermented fertilizer is sprinkled per mu to cultivate rotifers. As the opening bait for the fry pond, and set up the water inlet and drainage ditch, then add clean river water to the fish pond, the depth of the river water is half of the fish pond, and close the water inlet and outlet, and use a mesh grid when filling the water. Filter at the water inlet to prevent wild fish from entering the pool. The water source should be lake water or river water, with sufficient water, clean water and no pollution, and the dissolved oxygen content in the water is 7mg / L;

[0054] (2) Selection of fry: select fry with neat specifications, complete body surface, no deformity, no disease or injury;

[0055] (3) Putting the fry: Choose a ...

Embodiment 2

[0062] A method for culturing carp, comprising the steps of:

[0063] (1) Fish pond cleaning: Choose a pond with an area of ​​20 mu, a pond depth of 2.6 meters, and a silt thickness of 9 cm as a fish pond. 10 days before the fry enter the fish pond, sprinkle 3000 kg of fermented fertilizer per mu to cultivate rotifers. As the opening bait for the fry pond, and set up the water inlet and drainage ditch, then add clean river water to the fish pond, the depth of the river water is half of the fish pond, and close the water inlet and outlet, and use a mesh grid when filling the water. Filter at the water inlet to prevent wild fish from entering the pool. The water source should be lake water or river water, with sufficient water, clean water and no pollution, and the dissolved oxygen content in the water is 12mg / L;

Embodiment 3

[0072] A method for culturing carp, comprising the steps of:

[0073] (1) Fish pond cleaning: Choose a pond with an area of ​​7 mu, a pond depth of 2.2 meters, and a silt thickness of 8 cm as a fish pond. Eight days before the fry enter the fish pond, 2,700 kg of fermented fertilizer is sprinkled per mu to cultivate rotifers. As the opening bait for the fry pond, and set up the water inlet and drainage ditch, then add clean river water to the fish pond, the depth of the river water is half of the fish pond, and close the water inlet and outlet, and use a mesh grid when filling the water. Filter at the water inlet to prevent wild fish from entering the pool. The water source should be lake water or river water, with sufficient water, clean water and no pollution, and the dissolved oxygen content in the water is 8mg / L;

Abstract

The invention belongs to the technical field of aquaculture, and relates to a method for breeding Cyprinus carpio. The method comprises the following steps of: (1) fish pond cleaning; (2) fish fry selection; (3) fish fry releasing; (4) feed throwing and later-period management: carrying out stocking on juvenile fish, feeding the juvenile fish with powdery mixed feed containing rice bran meal, rapeseed meal and wheat bran powder at a ratio, in parts by weight, of 2:1.5:0.5 during 1-2 weeks in the early stage of stocking, performing feeding twice a day with a daily feeding amount of 2-3% of theweight of the fish, after 2 weeks, throwing carp feed 2-3 times a day with a daily feeding amount of 2.2-3.5% of the weight of the fish, and injecting water into the fish pond once every 5-7 days, wherein the amount of the added water is equivalent to 10-15 cm of the height of the fish pond; (5) wintering management; and (6) fish disease prevention and control. It is proven by experience that through the method, the incidence rate of Cyprinus carpio can be reduced significantly, the survival rate of breeding is improved, and the breeding income is increased.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, in particular to a method for culturing carp. Background technique [0002] Carp has the advantages of fast growth, good meat quality, and strong fecundity. At present, most of the carp culture follows the traditional water-changing pond culture mode. However, the traditional pond culture of fish is carried out at the expense of consuming a lot of natural resources, that is, it is manifested in the increasing occupation of land resources, the increasing consumption of water resources, and the increasing consumption of biological resources, etc. , and during the breeding process, a large amount of organic matter such as residual bait, feces, dead organisms, and sediments in aquaculture water is accumulated, and the content of ammonia nitrogen and nitrite is greatly increased, which poses a serious threat to the cultured fish and the surrounding environment. Incomplete pond treatment is easy t...
