Problems solved by technology

The existing grouper breeding process often requires the use of oxytocic agents in order to speed up the reproduction, which will produce some side effects. If no oxytonic agents are used, the fertilization rate and hatching rate are low, which affects the large-scale breeding of grouper fish

Abstract

The invention provides a method for rapid propagation of grouper, comprising the following steps: selecting female and male grouper as parents; selecting an indoor pond, the pond is connected to a water circulation device, and feeding nutrient material every day, and the nutrient material includes the following raw materials in parts by weight : eel, loach, snail meat, oyster, mussel meat and pellet feed; the pellet feed includes the following components: corn gluten powder, spirulina powder, selenium-enriched sweet potato powder, astaxanthin, multivitamins, antibacterial peptides , garlic powder, krill powder, soybean lecithin, motherwort powder, Eclipta extract, trilactyl glyceride; use green light, white light and yellow light to irradiate in sequence every day, first use green light, then white light, and finally Irradiate with yellow light; when the parent fishes are sexually mature, eggs will be fertilized naturally, and the fertilized eggs will be fished out and moved into the cultivation pond for hatching to obtain larvae. By adopting the grouper rapid propagation method of the present invention, the sexual maturity time of the parent fish is fast, the spawning amount of the parent fish is high, and the fertilization rate and hatching rate are relatively high.

Description

technical field [0001] The invention relates to the technical field of grouper breeding, in particular to a rapid breeding method for grouper. Background technique [0002] Grouper, as an important species of marine fish farming, has a large market demand. The existing grouper breeding process often needs to use oxytocic agents in order to speed up the reproduction, which will produce some side effects. If no oxytocic agents are used, the fertilization rate and hatching rate are low, which affects the large-scale breeding of grouper fish. Therefore be badly in need of a kind of new breeding method, solve above-mentioned technical problem. Contents of the invention [0003] In view of this, the present invention proposes a method for rapid propagation of grouper, with fast sexual maturation time of parent fish, high spawning capacity of parent fish, high fertilization rate and hatching rate. [0004] Technical scheme of the present invention is realized like this: [000...
