Problems solved by technology

[0007] In early spring and autumn, the temperature and water temperature are unstable, making it difficult to determine the dosage of GnRH analogues, and the efficacy of the medicine cannot be guaranteed; coupled with environmental changes, the stress response after using the medicine is intensified, often resulting in low artificial reproduction efficiency
[0008] ③ Rare fish are poorly sens

Embodiment 1

[0032] This example 1 is a gonadotropin-releasing hormone dual-path reproductive regulation drug for artificial reproduction of grass carp whose eggs have developed to stage IV. According to each kg female fish consists of the following raw materials:

[0033] Gonadotropin-releasing hormone 2 μg

[0034] Domperidone 2mg

[0035] Isoflavones and their analogs 1mg.

[0036] The artificial propagation method of using the above-mentioned medicines in fish is to dissolve gonadotropin-releasing hormone in water at normal temperature, then dissolve domperidone, isoflavones and similar substances in water and mix them, and inject them intramuscularly. The dosage is per kilogram The amount of each component added to the female fish during the ovulation period is: 1.5 μg of gonadotropin-releasing hormone, 1 mg and 0.5 mg of domperidone, isoflavones and the like; : Gonadotropin-releasing hormone 0.5μg, domperidone, isoflavones and similars 1mg, 0.5mg respectively, control the temperat...

Embodiment 2

[0038] Example 2 is a gonadotropin-releasing hormone dual-path reproductive regulation drug for artificial reproduction of white papaya. According to each kg female fish consists of the following components:

[0039] Gonadotropin-releasing hormone analog (GnRH-A) 12.5μg

[0040] Reserpine 4mg

[0041] Raloxifene 2mg.

[0042]The method of using the above-mentioned medicines for fish artificial reproduction is to dissolve gonadotropin-releasing hormone in water at room temperature, then dissolve reserpine and raloxifene in water and mix them, and inject intramuscularly. The amount of each component added to the female fish during the ovulation period is: 10 μg of gonadotropin-releasing hormone analogues, 3 mg and 0.5 mg of reserpine and raloxifene respectively; The dosage is: 2.5 μg of gonadotropin-releasing hormone analogues, 1 mg of reserpine and raloxifene respectively, controlled ripening and eutrophication water temperature is 24 ℃ ~ 32 ℃, and the dosage for each kilogr...

Embodiment 3

[0044] Present embodiment 3 is used for three flower scale fish. The fish has 28 days as a reproductive cycle, and the gonadotropin-releasing hormone dual-path reproductive regulation drug is artificially propagated in one year. According to each kg female fish consists of the following components:

[0045] GnRH 25μg

[0046] Haloperidone 220mg

[0047] Tamoxifen 220mg.

[0048] The artificial reproduction method of using the above-mentioned drugs in fish is to dissolve gonadotropin-releasing hormone in water at room temperature, then dissolve haloperidol and tamoxifen in water and mix them, and inject them intramuscularly. The dosage is 1 kg of female fish The annual total amount of each component added during the ovulation period is: 20 μg of gonadotropin releasing hormone, 200 mg of haloperidol and tamoxifen respectively; the annual total amount of each component added per kilogram of female fish during the ripening period is: gonadotropin 5 μg release hormone, 20 mg ha...

Abstract

A medicine for dual-approach regulation to the fish reproduction is prepared from gonadotropin-releasing hormone or its analog, dopamine antagon, and selective estrogen receptor regulator. Its application method is also disclosed.

Description

Technical field: [0001] The invention is related to reproductive regulation medicine, especially related to gonadotropin-releasing hormone dual-path reproductive regulation medicine and fish artificial reproduction method. Background technique: [0002] The positive effect of GnRH (gonadotropin-releasing hormone) is to promote (+) animal fertility (sperm, egg maturation, ovulation, ovulation), and negative feedback inhibits (-) reproduction. [0003] GnRH analogues have been widely used in fish artificial breeding to artificially induce ripening and spawning of broodstock and cultured broodstock. The purpose is to lay eggs, fertilize and hatch under artificial breeding conditions and increase the reproductive rate. However, in production practice, there are the following: question: [0004] ①Fish dystocia and death [0005] In fish artificial breeding, it is difficult for farmers to grasp the dose threshold of GnRH analogues. If the dose is insufficient, there will be no ...
