Embodiment 1

[0013] The breeding method of Xianghua mud carp and herring hybrid new variety, comprises the following steps:

[0014] (1) Parent selection: capture female Xianghua mud carp over 2 years old, weighing 800g, with well-developed gonads and healthy gonads in rivers and rivers; select 5-year-old, weighing 10-20kg, mature and healthy gonads The male herring is used as the male parent, and the female and male of the parents are bred separately 6 months before the hybridization;

[0015] (2) Parental cultivation: Put the parents of Xianghua mud carp in step (1) into the imitation ecology Xianghua mud carp parent breeding pond, and feed a large amount of artificially cultivated diatoms to promote the development of their gonads; put the herring in the herring parent pond , feeding sufficient amount of screws for intensive cultivation;

[0016] (3) To induce labor: For the parent in step (2), select a parent with good maturity during the breeding season from May to June: the female p...

Embodiment 2

[0020] The breeding method of Xianghua mud carp and herring hybrid new variety, comprises the following steps:

[0021] (1) Parent selection: capture female Xianghua mud carp over 2 years old, weighing 600-800g, with well-developed gonads and healthy gonads in rivers and rivers; select 5-8 years old, weighing 10-20kg, gonad-developed The mature and healthy male herring is used as the male parent, and the male and female of the parents are bred separately 12 months before the hybridization;

[0022] (2) Parental cultivation: Put the parents of Xianghua mud carp in step (1) into the imitation ecology Xianghua mud carp parent breeding pond, and feed a large amount of artificially cultivated diatoms to promote the development of their gonads; put the herring in the herring parent pond , feeding sufficient amount of screws for intensive cultivation;

[0023] (3) To induce labor: For the parent in step (2), select a parent with good maturity during the breeding season from May to J...

Abstract

The invention discloses a breeding method of a new hybrid variety of sinilabeo decorus tungting and black carp. The method comprises the steps of parent selection, parent breeding, spawning induction, artificial insemination and incubation. The invention solves the difficult problem on the hybrid aspect of the sinilabeo decorus tungting and the black carp; through breeding tests, a hybrid F1 generation is omnivorous, which solves the difficult problems that due to the fact that the sinilabeo decorus tungting is of algae-feeding habit, a large amount of diatoms are needed in breeding, and food is generally unsatisfactory; the hybrid F1generation is characterized in that the hybrid F1generation is high in growing speed, large in individual size, good in meat quality, fresh in taste and close to the sinilabeo decorus tungting, wherein the growing speed of the hybrid F1generation is one time larger than that of the sinilabeo decorus tungting, and the individual size of the hybrid F1generation is 1.5 times of that of the sinilabeo decorus tungting; the hybrid F1generation has good production and application values.

Description

technical field [0001] The invention relates to the technical field of cultivating new varieties, in particular to a breeding method for hybrid new varieties of Xianghua dace and herring. Background technique [0002] Xianghua carp belongs to Cypriniformes, Cyprinidae, and the genus Sinina. It looks like Sinosa. Its dorsal fin has no hard spines. It mainly eats algae, plant debris and young leaves of plants in running water. Because Xianghua dace has a high total amount of umami amino acids, it is more delicious, and it also contains a variety of minerals and trace elements necessary for the human body. Among them, the content of calcium, potassium, and copper is higher than that of the other seven economic fishes, so it is very developed. use value. However, Xianghua dace grows slowly, is small in size, has special feeding habits, and is difficult to breed. [0003] Herring belongs to the order Cyprinidae, Cyprinidae, Arroa family, and the genus Herring. The head is wide...
