A kind of grouper feed additive and using method thereof

Abstract

The invention discloses a grouper feed additive and a method for using the same. It is composed of photosynthetic bacteria liquid, Bacillus pumilus powder and Lactobacillus acidophilus liquid. First, the Bacillus pumilus powder is mixed with the Lactobacillus acidophilus liquid and then mix the obtained mixed bacteria with the photosynthetic bacteria liquid; the mass percent content ranges of the three components are: the photosynthetic bacteria liquid is 18% to 22%, the Bacillus pumilus powder is 1% to 3%, and the acidophilic The lactobacillus liquid is 75-81%; add 10g-50g of additives to 1kg of basic feed, mix well with the basic feed and wrap it with emulsified fish oil. The invention is applicable to the healthy cultivation of the grouper, can obviously improve the activity of SOD, AKP and lysozyme in the fish body, thereby effectively promoting the growth of the grouper.

Description

technical field

[0001] The invention belongs to the field of aquaculture, and in particular relates to a grouper feed additive and a method for using the grouper feed additive. Background technique

[0002] The oblique-banded grouper (Epinephelus coioides) belongs to the genus Grouper of the family Anguidae, and is a rare marine economic fish with high edible value and health value; The fish farming industry has developed rapidly, and the grouper has become one of the important cultured species.

[0003] In the process of artificial breeding of oblique grouper, it is very important to prevent and manage diseases caused by bacteria, viruses, parasites, etc., especially for cage farms in high-density or highly polluted sea areas. The increased sensitivity of pathogens makes it easier to cause the occurrence and prevalence of diseases. Fishermen often rely on antibiotics to prevent grouper diseases, but the abuse of antibiotics has led to serious food safety problems. Therefo...
