Abstract

The invention provides a high-yield breeding method for groupers. The method comprises the following steps that before fry putting, grouper fry of the length of 3-5 cm are selected and placed in a composite solution of povidone iodine and pennisetum hydridum medicine liquid for a medicinal bath; an indoor pond is selected, and after the water quality of the pond is stable, the grouper fry after the medicated bath are put into the pond; in the breeding stage, before the average weight of the fishes is less than 0.5 kg, granular feed is put, wherein the granular feed is prepared from, by weight,30-40 parts of corn flour, 15-18 parts of seaweed powder, 3-5 parts of silkworm chrysalis powder, 23-28 parts of jackfruit powder, 1-2 parts of coconut oil, 5-7 parts of astaxanthin, 1-2 parts of antibacterial peptide and 0.1-0.3 part of vitamin C; when the average weight of the fishes is 0.5 kg or above, fermented feed is put, wherein the fermented feed is prepared from, by weight, 10-30 parts of sweet potatoes, 20-30 parts of soybean meal, 11-14 parts of peanut meal, 5-8 parts of nepenthes mirabilis, 10-15 parts of fructus arctii and 25-35 parts of distillers'grains for rice wine, and rhizobia and actobacillus plantum are added to all the raw materials for fermentation; adult fishes are harvested. By means of the method, the obtained groupers have high disease resistance and survival rate, a large specification, a low coefficient of variation and a large yield.

Description

technical field [0001] The invention relates to the technical field of grouper, in particular to a high-yield breeding method for grouper. Background technique [0002] With the division of prohibited and restricted areas, the area of ​​grouper aquaculture has been further reduced, and the scale of industrial indoor aquaculture has continued to expand. However, the weather is changeable, such as continuous high temperature weather, which leads to the decline of indoor environmental quality, affects the growth of grouper, increases its mortality, induces mutation, etc., reduces the output of grouper and reduces the income of farmers. Therefore be badly in need of a kind of new grouper high-yield breeding method, solve the above problems. Contents of the invention [0003] In view of this, the present invention proposes a high-yield culture method for grouper, which can obtain grouper with strong disease resistance, high survival rate, large size and low coefficient of vari...
