Method for inducing hormone soaked loaches

Abstract

The invention relates to a method for inducing hormone soaked loaches. The method comprises the following steps: (1) selecting a mature loach parent in water at the temperature of between 21 and 29 DEG C; and (2) taking a mixture of domperidone maleate, luteotropin releasing hormone d-ala analog and chorionic gonadotropin as oxytocic hormones, and soaking the loach parent with a soaking solution which is prepared by mixing the oxytocic hormone, pentoxifylline and edible oil in normal saline, wherein the dosage of the domperidone maleate is between 100 and 300mg / kg, the dosage of the luteotropin releasing hormone d-ala analog is between 200 and 600mu g / kg, the dosage of the chorionic gonadotropin is between 15,000 and 30,000IU / kg, and the dosage of the normal saline is between 0.2 and 0.3kg / kg; and when the loach parent is soaked, the temperature of the soaking solution is controlled to be between 21 and 29 DEG C, and the soaking time is controlled to be between 0.5 and 8 hours. The aim of inducing the loach parent can be realized through soaking instead of injection.

Description

technical field [0001] The invention relates to a method for inducing labor of loach, in particular to a method for inducing labor of loach soaked in hormones. Background technique [0002] Loach (Misgurnus arguillicaudatus) belongs to Cyprinidae, Loach family, Loach genus, commonly known as "pink loach". It has a wide distribution and strong adaptability, and is an omnivorous small freshwater economic fish. Loach meat is delicious, has high nutritional value and medicinal value, and is deeply loved by consumers at home and abroad. Loach farming has great development potential, but the number of natural seedlings of loach can no longer effectively supply the breeding needs, which restricts the development of loach farming industry. [0003] The traditional method of injecting oxytocin will encounter the problem that loaches are difficult to catch. In the artificial breeding process, due to the small size of the loach, it takes a lot of time to catch and inject one by one,...

The development potential of loach farming is great, but the number of natural seedlings of loach can no longer effectively supply the breeding needs, which restricts the development of loach farming industry

[0003] The traditional method of injecting oxytocin will encounter the problem that loach is difficult to catch

In the artificial breeding process, due to the small size of the loach, it takes a lot of time to catch and inject one by one, which affects the damage of the parents.

[0004] Chinese patent CN200710114040.9 discloses a slow-release hormone granule that induces the maturation of the gonads of the stone seabream and its preparation method, which solves the problems of troublesome operation and great stimulation to the fish body existing in the method of direct injection of the hormone

However, it is also by injecting liquid medicine into the body of the parent, so that the liquid medicine becomes solid in the body of the parent and released slowly so as to achieve long-term release of the drug effect, which will cause greater damage to the parent.
