Embodiment 1

[0027] In June 2017, the method of the present invention was used to cultivate the wild parent of Pachyrhiza sideraculus in the inter-office fish farm of Zhaoxing Fish Farming Co., Ltd., Shunchang County, Fujian Province, which broke through the key technology of artificial breeding, and realized the side-stripe for the first time. Artificial breeding of pachyrhizus. A total of 3 batches of spawning were induced, a total of 109 females were induced, and 64 were successfully induced, with an average induction rate of 58.7%; 51,300 eggs were obtained, and 34,400 fertilized eggs were obtained, with an average fertilization rate of 67.1%; 24,300 water flower seedlings were hatched, with an average The hatching rate is 70.6%. After 45-55 days of cultivation, a total of 17,900 summer flower seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of seedling cultivation reached 73.7%.

[0028] Its specific breeding steps are:

Embodiment 2

[0048] From May to June 2018, the method of the present invention was used again at the seed breeding cooperation base of the Fujian Freshwater Fisheries Research Institute to carry out the artificial breeding and production of the wild parent of Pachyrhiza lateralis. A total of 5 batches of spawning were induced, a total of 233 females were induced, and 169 were successfully induced, with an average induction rate of 72.5%; 133,200 eggs were obtained, and 92,400 fertilized eggs were obtained, with an average fertilization rate of 69.4%; 71,700 water flower seedlings were hatched, The average hatch rate is 77.6%. After 42-51 days of cultivation, a total of 54,800 summer flower seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of seedling cultivation reached 76.4%. Its specific breeding steps are:

[0049] (1) Parental cultivation:

[0050] a) Daily cultivation: use 1667 m 2 1.3-1.6 m earthen ponds were used to cultivate the wild...

Embodiment 3

[0064] From May to July, 2019, at the breeding base of pachyrhiza fryensis in Fujian Province (Jizhou base of Zhaoxing fish breeding Co., Ltd., Shunchang County, Fujian Province), the method of the present invention was used to cultivate wild parents of pachyrhiza lateralis. Its artificial batch breeding. A total of 6 batches of spawning were induced, with a total of 582 females being induced to spawn, 467 of which were successfully induced, with an average induction rate of 80.2%; 366,400 eggs and 271,500 fertilized eggs were obtained, with an average fertilization rate of 74.1%; 198,500 water flower seedlings were hatched, The average hatching rate is 73.1%. After 41-53 days of cultivation, a total of 165,400 summer flower seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of seedling cultivation reached 83.3%. Its specific breeding steps are:

[0065] 1) Parental breeding:

[0066] a) Daily cultivation: use 1667 m 2Cultivate ...

Abstract

The invention discloses an artificial breeding method of acrossocheilius parallens (Acrossocheilius parallens). According to the artificial breeding method, protospecies parent fishes captured from the field are subjected to steps of daily cultivation of parents, prenatal cultivation, prenatal ripening, artificial spawning induction, artificial insemination, artificial incubation, fry cultivationand the like, whole-artificial fry culture of the acrossocheilius parallens is realized. The invention provides a pattern suitable for large-scale production of acrossocheilius parallens fries. The technique breaks through the technique bottleneck of artificial breeding of the acrossocheilius parallens, whole artificial fry culture of the acrossocheilius parallens is realized for the first time athome and abroad, technical support and fry guarantee are provided for germplasm resource repair of acrossocheilius parallens national-level aquatic product germplasm resource conservation zones and other water areas having natural population distribution, and a good base is established for the work of the large-scale fry culture, artificial raising and the like of the acrossocheilius parallens.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an artificial breeding method of pachyrhiza sideraceae. Background technique [0002] my country's topography and landforms are varied, and the inland areas have a wide drainage area and are rich in local freshwater fish resources, among which there are many species with development and utilization value. These local characteristic fish resources have important ecological value and genetic breeding value, and at the same time have the characteristics of rich nutrition, delicious meat and unique flavor. Aquatic germplasm resources are an important material basis for aquatic breeding, aquaculture production, resource restoration and fishery technology development. Although resource investigation, species identification, seedling breeding and artificial domestication have been initially carried out for conservation and development of some varieties, most of them are still in ...
