Method for breeding Cyprinus carpio

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...

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 accumulates, and the content of ammonia nitrogen and nitrite increases significantly, posing a serious threat to the aquaculture fish and the surrounding environment. If the pond is not treated thoroughly, it is very easy to be infected with gill rot bacteria, which not only affects the output of carp, but also affects the absorption of nutrients by carp. The survival rate of carp is only about 85%, which seriously hinders the sustainable and healthy development of pond culture.
