Abstract
The invention relates to an artificial reproduction method for wild Anabarilius liui liui (Chang), and belongs to the technical field of fish farming, inheritance and breeding. The method comprises the steps of odinagogue injection, natural oviposition and fertilization and artificial incubation. The method comprises the specific steps that 1, when water temperature is 20.5 DEG C, odinagogue is injected, the dosage of the odinagogue injected to female fishes is LRH-A28 micrograms/kg+DOM2 mg/kg, and the dosage of the odinagogue injected to male fishes is halved; 2, an artificial egg collector of a palm sheet is hung in spawning pool, natural oviposition and fertilization are carried out, and the effect time is 17 h to 20 h; 3, an incubation trough is adopted for running water incubation, fertilized germ cells are distributed on the palm sheet for shading incubation, the water level in the incubation trough is kept to be 15 cm in the incubation process, and the exchange capacity of more than 100 times per day is provided. The method has the advantages of being easy and convenient to operate, low in cost and high in spawning rate, fertilization rate and incubation rate.
Description
Technical field
The present invention relates to a kind of wild Xichang whitefish
anabarilius liui liui(Chang) artificial fecundation method, belongs to fish culture, heredity and breeding technical field.
Background technology
Xichang whitefish
anabarilius liui liui(Chang), in classification, belong to Cypriniformes Cypriniformes, Cyprinidae Cyprinidae Culter subfamily Cultrinae whitefish genus
anabariliuscockerell, is distributed in the tributary in Jinsha jiang River.Xichang whitefish body is elongated slightly flat-sided, and base portion is from anus after abdomeinal fin for abdomen rib, and side part squama edge is black, and each fin is all without speckle.The Yongsheng County local people's of whitefish Shen Shou Yunnan Province, Xichang favor.Wild resource is fewer and feweri, and in the markets of producing areas, own difficulty is sought its track, only at source accidental, and every kilogram of price is up to 600 yuan.
For protection and exploitation Xichang this Wild fish resources of whitefish, 2014, by Yunnan Institute of Fisheries Science and the cooperation of raiser Wu Mei base, carry out Xichang whitefish artificial propagation techniques research.Xichang whitefish first artificial propagation succeeds.
By literature search, have no the open report identical with the present invention.
Summary of the invention
The object of the present invention is to provide the artificial fecundation method of a kind of wild Xichang whitefish.
The artificial fecundation method of wild Xichang of the present invention whitefish, comprises injection ocyodinic, natural spawning fertilization and artificial incubation step, specific as follows:
(1), injection ocyodinic
Adopt shot method injection ocyodinic, when 20.5 ℃ of water temperatures, inject ocyodinic, dosage is raun injection LRH-A2 8 μ g/kg+DOM 2mg/kg, and milter dosage reduces by half;
(2), natural spawning fertilization
The spawning inducing pool of wild Xichang whitefish of having injected ocyodinic being put into the artificial fish nest that hangs with brown sheet, completed natural spawning fertilization after 17-20 hour;
(3), artificial incubation
Adopt incubation tank Lotic hatching, during hatching, incubation tank water level remains on 15cm, and 100 times of/day above exchange capacities are provided, and water temperature is 18 ℃-21.5 ℃; The fertilized egg cloth of after fertilization carries out shading hatching on brown sheet, after 96 hours, starts membrane, and all the fry membrane time is 108 hours.
The present invention has easy and simple to handle, with low cost, and parent population is more consistent estrus time, spawning rate, the advantage that fertility rate and hatchability is high.For developing the indigenous stock of fish-Xichang whitefish, laid good basis.
embodiment:
Select wild Xichang whitefish of Yongsheng County, Yunnan Province Green Lake dragon's pool
anabarilius liui liui(Chang), carry out as follows artificial propagation:
1, injection ocyodinic
Adopt shot method injection ocyodinic, when 20.5 ℃ of water temperatures, inject ocyodinic, dosage is raun injection LRH-A2 8 μ g/kg+DOM 2mg/kg, and milter dosage reduces by half;
2, natural spawning fertilization
The spawning inducing pool of wild Xichang whitefish of having injected ocyodinic being put into the artificial fish nest that hangs with brown sheet, completed natural spawning fertilization after 17 or 20 hours;
3, artificial incubation
Adopt incubation tank Lotic hatching, during hatching, incubation tank water level remains on 15cm, and 100 times of/day above exchange capacities are provided, and water temperature is 18 ℃ or 21.5 ℃; The fertilized egg cloth of after fertilization carries out shading hatching on brown sheet, after 96 hours, starts membrane, and all the fry membrane time is 108 hours.
Result of implementation shows:
On March 15th, 2014, the 39 groups of Xichang whitefish of hastening parturition altogether, 39 tail rauns are by injection ocyodinic, and spawning rate reaches 92.3%, obtains altogether 260,000, ovum; Fertilization rate reached 80.9%, obtains 210,000, fertilized egg.
When water temperature is 18-21.5 ℃, after artificial insemination 96 hours start membrane, and all the fry membrane time is 108 hours.Statistics obtains fry 16.6 ten thousand tails, and incubation rate is 79%.
After 178 hours, Xichang whitefish fry can be put down trip, and artificial propagation succeeds.
Claims (1)
1. an artificial fecundation method for wild Xichang whitefish, is characterized in that the artificial fecundation method of this wild Xichang whitefish comprises injection ocyodinic, natural spawning fertilization and artificial incubation step, specific as follows:
