Embodiment Construction

[0018] Below in conjunction with embodiment the present invention is described in further detail:

[0019] A kind of method for breeding and breeding of carp, comprising the following steps:

[0020] A. Prepare broodstock

[0021] a. Source of broodstock: The original broodstock of Shanghehua carp was purchased from the traditional rice field fish farming area, carefully selected and cultivated manually;

[0022] b. Selection of parent fish: The age of parent fish is in the range of 2 to 5 years old, and the weight is more than 300 grams. It is required to be strong, plump, active, and free of disability lesions;

[0023] c. Male and female identification:

[0024] 1) Non-reproductive season: females are large, with a large and soft abdomen, and a large and prominent cloaca; males are obviously smaller in the same batch of fish, with a narrow and slightly hard abdomen, and a small and slightly inward cloaca concave;

[0025] 2) Reproductive season: Females have no pectoral...

Abstract

The invention discloses a breeding method of Procypris merus and relates to the technical field of fishery. The method includes the steps of preparing parent fishes, performing artificial breeding and variety breeding, performing fry rearing, separating and optimally selecting summerlings, rearing and optimally selecting fingerlings and the like. By the use of the method, the problem that germplasm of the variety of Procypris merus degrades is solved.

Description

technical field [0001] The invention relates to the technical field of fish farming, in particular to a method for breeding and selecting grass carp in a pond. Background technique [0002] Hehua carp is a carp species with black and bright body color. It is mainly cultivated in rice fields in the southern mountainous area. The basic work is backward, and most farmers rely on self-propagation and self-cultivation to solve the source of fish seedlings, resulting in the widespread phenomenon of inbreeding of local Hehua carp, uneven quality of fish species, and disorderly development of production, which eventually leads to the germplasm of Hehua carp species. Severe degradation, the consequence of the general decline in the productivity of rice field cultured carp. Contents of the invention [0003] The purpose of the present invention is to provide a method for breeding and breeding of the grass carp, which can solve the problem of germplasm degradation of the grass carp ...
