Large-scale artificial breeding technology of Allogynogenetic crucian carp

Abstract

The invention discloses a large-scale artificial breeding technology of Allogynogenetic crucian carp, which comprises the following steps: (1) using Xinguo red carp as a male parent and culturing by using the same method as common carps; using Fangzheng carp as a female parent, the female parent and the male parent are cultured in different ponds, conducting feeding training, controlling the feeding rate, changing water, adding oxygen, stopping changing the water before 15d near the breeding season; (2) formulating oxytocin into an injection and injecting it into fish at a time; (3) fabricating a fish nest with willow root and palm bark, placing the fish nest immediately below the nearshore water surface of a spawning pond immediately after spawning induction in the step (2); (4) preparingthe spawning pond; (5) conducting hydrostatic inflatable incubation. The large-scale artificial breeding technology of Allogynogenetic crucian carp can breed high-quality Allogynogenetic crucian carpfry with high hatchability and survival rate, ensure the production demand of Allogynogenetic crucian carp fry and improve the economic benefits of Allogynogenetic crucian carp breeding farmers, andimprove the sustainable development of Allogynogenetic crucian carp breeding industry and the overall ecological, economic, and social benefits of the fishery industry.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a large-scale artificial propagation technology of heterogeneous gibel carp. Background technique [0002] Allogenetic gibel carp is the gynogenetic offspring of Fangzheng gibel carp eggs fertilized with Xingguo red carp sperm. Since it was successfully bred in 1976, it has been popularized in the whole country and has achieved good social and economic benefits. The heterogeneous gibel crucian carp is delicious and nutritious, and is favored by the masses. In order to further promote breeding, the supply of high-quality seed must be satisfied as much as possible. [0003] At present, the heterogeneous gibel crucian carp is an excellent variety that is reproduced by using heterologous sperm to stimulate gibel carp eggs for gynogenesis. This breeding technology has been extended and applied in production practice. Although the artificial breeding technology of he...

Problems solved by technology

Although the artificial breeding technology of heterogeneous gibel carp is not complicated, small-batch breeding can be done by ordinary farms, but in order to carry out large-scale artificial breeding, it is necessary to be familiar with every link of the breeding technology. cause large economic losses to production
