Embodiment 1

[0027] In June 2017, at the Jixia Fish Seed Farm of Zhaoxing Fish Breeding Co., Ltd., Shunchang County, Fujian Province, the method of the present invention was used to cultivate the wild parents of S. Artificial rearing of the thick-lipped fish. A total of 3 batches were induced, 109 female fish were induced in total, 64 were induced successfully, with an average induction rate of 58.7%; 51,300 eggs and 34,400 fertilized eggs were obtained, with an average fertilization rate of 67.1%; The hatching rate was 70.6%. After 45-55 days of cultivation, a total of 17,900 Pseudomonas splendens seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of the seedlings reached 73.7 %.

[0028] The specific breeding steps are:

[0029] (1) Parental cultivation:

[0030] a) Daily cultivation: use 1000 m 2 , The soil pond with a water depth of 1.2 to 1.4 m is used to cultivate the wild parents of S. chinensis, and the stocking density is 5,000 / mu; ...

Embodiment 2

[0048] From May to June 2018, the artificial breeding and production work of the wild parents of Pseudomonas serrata was carried out again by using the method of the present invention in the seed breeding cooperation base of the Fujian Institute of Freshwater Fisheries. A total of 5 batches were induced, a total of 233 female fish were induced, 169 were induced successfully, with an average induction rate of 72.5%; 133,200 eggs and 92,400 fertilized eggs were obtained, with an average fertilization rate of 69.4%; The average hatching rate was 77.6%. After 42 to 51 days of cultivation, a total of 54,800 Pseudomonas chinensis seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of the seedlings reached 76.4 %. The specific breeding steps are:

[0049] (1) Parental cultivation:

[0050] a) Daily cultivation: using 1667 m 2 , The soil pond with a water depth of 1.3 to 1.6 m is used to cultivate the wild parents of S. chinensis, and the...

Embodiment 3

[0064] From May to July, 2019, in the breeding base of the fry of Pseudomonas splendens 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 the wild parents of C. Its artificial batch breeding. A total of 6 batches of induced labor, a total of 582 female fish were induced, and 467 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%; hatched 198,500 water flower seedlings, The average hatching rate was 73.1 %. After 41 to 53 days of cultivation, a total of 165,400 Pseudomonas chinensis seedlings with an average size of more than 3.0 cm were obtained, and the average survival rate of the seedlings reached 83.3 %. The specific breeding steps are:

[0065] 1) Parental breeding:

[0066] a) Daily cultivation: using 1667 m 2Cultivate the wild parents of th...

Abstract

The invention discloses a side-striped thick-lipped fish ( Acrossocheilius parallelens ) artificial breeding method, which is to realize the production of the pachyrhiza sidelonga through the steps of parental daily cultivation, prenatal cultivation, prenatal ripening, artificial induction, artificial insemination, artificial hatching and seedling cultivation of the original species of broodstock caught from the wild. fully artificial breeding. The present invention provides a mode suitable for the large-scale production of Pachychus lateralis seedlings. This technology breaks through the technical bottleneck of artificial breeding of Pachychus lateralis, and realizes the full artificial breeding of Pachychus lateralis for the first time at home and abroad. It provides technical support and seed guarantee for the restoration of germplasm resources in the National Aquatic Germplasm Resources Protection Area and other waters with natural population distribution, and lays a solid foundation for the large-scale nursery and artificial breeding of Pachychinus lateralis. a good foundation.

Description

technical field [0001] The invention belongs to the field of aquaculture, and in particular relates to an artificial breeding method for the side-striped fish. Background technique [0002] my country's topography and landforms are varied, and the inland area has a wide basin area and is rich in local freshwater fish resources, of which there are many varieties 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 the development of fishery science and technology. Although some varieties have initially carried out resource survey, variety identification, seedling breeding and artificial domestication and other protection and development and utilization work, mos...
