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 rapid propagation method for groupers. The method comprises the following steps that female and male groupers are selected as parents; an indoor pond is selected and communicated with a water circulation device, and a nutrient material is fed every day, wherein the nutrient material is prepared from, by weight, eels, loach, sea whelk meat, oysters, clam meat and pellet feed, and the pellet feed is prepared from corn protein powder, spirulina powder, selenium-enriched sweet potato powder, astaxanthin, multivitamin, antibacterial peptide, garlic powder, krill powder, soybean lecithin, herba leonuri powder, a herba ecliptae extract and trilacti-glyceride; green light, white light and yellow light are sequentially adopted for irradiation every day, wherein the green light is adopted for irradiation at first, then the white light is adopted for irradiation, and finally, the yellow light is adopted for irradiation; after the parent fishes are sexually mature, naturalspawning and fertilization are conducted, and fertilized eggs are fished out and moved into a breeding pond for hatching to obtain fry. By means of the rapid propagation method for the groupers, thesexual maturity time of the parent fishes is short, the spawning yield of the parent fishes is high, and the fertilization rate and the 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...
