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, soak them in a liquid containing furazolidone, etc., and slowly move them into intensive cultivation pools or cages. 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.

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

The invention discloses a slow-release oxytocic agent for artificially inducing grouper gonad development and maturation, ovulation and ejaculation. 10%, 75-95% cholesterol, 1-19% cellulose; 1-3% vegetable oil is added to the formula components, mixed evenly, and cylindrical pills are made with a special mold. The invention is used to bury the grouper in the body to induce the maturation of the gonads to achieve ovulation and sperm discharge, so as to meet the needs of the grouper artificial seedling industrialization and large-scale breeding for seedlings.

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 (Perciformcs), Family (Serranidae), grouper (Epinephelus), more than 400 species in the world, 45 species have been recorded in the coastal areas of my country's mainland (Zhu Qian, 1998), the phenomenon of female first and then male is common in its individual development, and the female gonads are divided into batches. Mature spawns many times, the amount of eggs laid is small, the amount of semen released by the transsexual male fish is small, and the continuous ejaculation time is short. [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 ...
