Embodiment 1

[0021] Luteinizing hormone releasing hormone A 2 (LHRH-A 2 ) 1%, 17α-hydroxyprogesterone (17α-hydroxyprogesterone, 17α-P) 3%, cholesterol (Cholesterol) 90%, cellulose (Cellulose) 4%, add 2% vegetable oil and mix well, use mold to make cylinder shaped pills. The parent fish used in the experiment were anesthetized with 2-phenoxyethanol or musmol, and the dosage of the slow-release oxytocic agent was determined according to the size of the fish body and the state of gonad development. After the site is sterilized with anti-inflammatory drugs, put the fish into the furazolidone liquid to soak, (after the fish wakes up,) slowly move into the intensive cultivation pool or cage. After the above operations, the broodstock implanted with the slow-release pills not only survived 100%, but also 100% of the female broodstock matured or ovulated; 100% of the male broodstock matured and ejaculated, and the amount of semen was 3-5 times that of the control group.

Embodiment 2

[0023] Luteinizing hormone releasing hormone A 2 (LHRH-A 2 ) 0.5%, 17α-hydroxyprogesterone (17α-hydroxyprogesterone, 17α-P) 5.5%, cholesterol (Cholesterol) 75%, cellulose (Cellulose) 18% and 1% vegetable oil, mix well, make cylindrical pill, experiment The parent fish is anesthetized with 2-phenoxyethanol or musmol, and the dosage of the slow-release oxytocic agent is determined according to the size of the fish body and the development of the gonads. After the anti-inflammatory drugs are used to reduce inflammation, put them into the liquid containing furazolidone and other medicines to soak, and then slowly move them into the intensive cultivation pool or cage. After the above operations, the broodstock implanted with the slow-release pills not only survives 100%, but also the female broodstock matures or ovulates 100% ; 100% mature male broodstock ejaculate, and the amount of semen is 3-5 times that of the control group.

Embodiment 3

[0025] Luteinizing hormone releasing hormone A 3 (LHRH-A 3 ) 0.1%, 17α-hydroxyprogesterone (17α-hydroxyprogesterone, 17α-P) 8%, cholesterol (Cholesterol) 80%, cellulose (Cellulose) 9.9% and 2% vegetable oil mix uniformly, make cylindrical pill. The parent fish used in the experiment were anesthetized with 2-phenoxyethanol or musmol, and the dosage of the slow-release oxytocic agent was determined according to the size of the fish body and the state of gonad development. After the parts are sterilized with anti-inflammatory drugs, they are soaked in a liquid containing furazolidone. (After the fish wakes up,) slowly move the fish into the intensive cultivation pool or cage. After the above operations, the broodstock implanted with the slow-release pills not only survived 100%, but also matured or ovulated 100% of the female broodstock; 100% of the male broodstock matured and ejaculated, and the amount of semen was 3-5 times that of the control group. The fertilization rate is...

Abstract

A slow-releasing oxytocic for artificially inducing the maturation of epinephelus' sex gland and the ovulation or ejaculation by embedding it in body of epinephelus is prepared from luliberin like, 17 alpha-hydroxyprogesterone, cholesterin, cellulose and plant oil through proportional mixing and moulding.

Description

technical field [0001] The invention relates to a slow-release oxytocic agent for artificially inducing grouper gonad development and maturation, ovulation and ejaculation in aquaculture, and also relates to the application of the slow-release oxytocic agent. Background technique [0002] Grouper belongs to Perciformes (Perciformes), Serranidae (Serranidae), grouper (Epinephelus), more than 400 species in the world, and 45 species have been recorded in the coastal areas of my country's mainland (Zhu Qian, 1998). There is a phenomenon of females first and then males. The female gonads mature in batches and spawn multiple times. The amount of eggs laid is small. [0003] The artificial reproduction of grouper is one of the difficult problems in marine aquaculture in the world, and the maturation of gonads and final ovulation and semen of grouper are the key points of artificial breeding. Grouper is a valuable seawater economic fish. It is an important seawater economic fish i...
