Embodiment Construction

[0019] 10 first-year-old wild carps were captured from the waters of the Liaohe River, divided into 5 groups according to the ratio of female to male at 1:1, and cultivated in an open-air pond I with an area of ​​3 mu for two years until the gonads mature. The water depth of the open-air pond I is 1.5 to 2.5 meters. The dissolved oxygen in the breeding water reaches more than 3 mg / L. From June to August, use EM bacteria once a week to adjust the water quality and ensure the water quality of the whole breeding water is good; the EM bacteria is a kind of mixed bacteria, generally including photosynthetic bacteria, yeast , lactic acid bacteria and other beneficial bacteria can be used to improve water quality. During the cultivation period, carp feed was fed twice a day, and the daily feeding amount accounted for 2 to 3% of the fish's body weight.

[0020] The 5 groups of wild carp with mature gonads were inspected by modern molecular biology techniques such as ELISA technology, ...

Abstract

The invention provides a breeding method of pure red carp. The breeding method comprises the following steps that (1) wild carps are captured from a natural water area and are cultivated until gonadsmature; (2) male wild carps and female wild carps with mature gonads are subjected to artificial spawning, fertilization and hatching to obtain sub-generational individuals; (3) the sub-generational individuals are cultivated to reach 3 cm / tail to 5 cm / tail, red carp individuals are separated and screened as reserve parent fish; (4) the separated and screened red carp individuals are cultivated again until gonads mature; and (5) male parent fish and female parent fish are selected from the red carp individuals with mature gonads, and are subjected to artificial spawning, fertilization and hatching to obtain sub-generational red carp individuals. The breeding method has the beneficial effects that pathogens are screened, it is ensured that the parent fish does not have the pathogens, and the vertical transmission of disease is avoided; drugs are not used in the whole process; the artificially cultivated red carps are high in yield, large in scale and high in survival rate; and the cultivated red carps are high in ornamental value and economic value, better economic, social and ecological benefits can be produced, and prospects are broad.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a seed production method of pure-line red carp. Background technique [0002] Carp belongs to Cyprinidae and Cyprinus. Carp is a temperate freshwater fish native to Asia.
