Embodiment 1

[0028] A kind of artificial propagation method of pointed naked carp, comprises the following steps:

[0029] A. Broodstock selection: In April, catch the wild carp that has entered the IV stage in the developmental period as artificial breeding parents. After the parents are sterilized, the female and male fish are separated for temporary breeding;

[0030] B. Artificial induced labor: using luteinizing hormone-releasing hormone analog LRH-A 2 and carp pituitary PG mixture as an oxytocic agent, LRH-A 2 The dosage of PG mixture is 10ug / kg, and the dosage of PG mixture is 8mg / kg; adopt the double injection method to induce labor for the female carp;

[0031] C. Artificial insemination: use anhydrous dry method for insemination. After the female fish has an effect time of 48 to 72 hours, artificially squeeze the eggs of the female fish, squeeze the eggs of the pointed naked carp into a dry white porcelain bowl, and pour 3 ~ After 4 drops of male semen, stir thoroughly for 30 s...

Embodiment 2

[0035] This embodiment is on the basis of embodiment 1:

[0036] It also includes postpartum care of broodstock: after sperm collection and egg squeezing, broodstock are soaked in 1% glucose solution for 1 hour, and then each fish is injected with gentamicin, and the broodstock after injection is transferred to the flowing water cultivation tank , using small cold-water fish as bait fish to lure them to eat.

Embodiment 3

[0038] This embodiment is on the basis of embodiment 1:

[0039] It also includes postpartum care of broodstock: after sperm collection and egg squeezing, broodstock are soaked in 1% glucose solution for 1 hour, and then each fish is injected with gentamicin, and the broodstock after injection is transferred to the flowing water cultivation tank , using small cold-water fish as bait fish to lure them to eat.

[0040] The dose of the injected gentamicin is 0.2mg / kg body weight.

Abstract

The invention provides an artificial propagation method of oxygymnocypris stewartii. The method comprises the following steps of A, selection of parent fishes; B, artificial spawning acceleration; C,artificial insemination; D, hatching. The method can obviously increase the hatching rate and emergence rate of oxygymnocypris stewartii, and has important significance on protection of the special fishes and reasonable development of the population resources of the special fishes.

Description

technical field [0001] The invention relates to the technical field of fish reproduction, in particular to an artificial reproduction method of the naked carp. Background technique [0002] Naked carp, belonging to Cyprinidae, Schizothorax subfamily, and genus Naked carp, is one of the important indigenous economic fish in Tibet. The naked carp belongs to the highly specialized grade among the three grades of Schizothorax, and it is only distributed in the main and tributary areas of the middle reaches of the Yarlung Zangbo River above an altitude of 3,600 meters. Due to the high altitude and low annual average water temperature, a special ecological environment is formed. The naked carp adapts to the environment with clear water flow and precipitation and alpine snow water as the source, and mainly feeds on other fish and aquatic insects. In recent years, affected by the ecological environment and human activities, the habitat and living environment of the naked carp have ...
