[0040] The preparation method of above-mentioned aquaculture feed comprises the following steps:

[0041] (1) Preparation of the extract of the aerial part of Scutellaria baicalensis: extract the aerial part of Scutellaria baicalensis with an extraction solvent, concentrate, and dry to obtain the extract of the aerial part of Scutellaria baicalensis;

[0042] (2) Take the extract of the aerial part of Scutellaria baicalensis according to the parts by weight, dissolve it in water, spray it on the surface of the feed, and dry it;

[0043] (3) Spraying the fish oil on the surface of the feed obtained in step (2).

[0044] In some of these embodiments, the preparation method of the above-mentioned aquaculture feed comprises the following steps:

[0045] (1) Preparation of the extract of the aerial part of Scutellaria baicalensis: extract the aerial part of Scutellaria baicalensis with an extraction solvent, concentrate the obtained extract, adjust the pH to 2-3, separate with a m...

Embodiment 1

[0056] The preparation method of embodiment 1 aquaculture feed

[0057] Include the following steps:

[0058] (1) Preparation of the water extract of the aerial part of Scutellaria baicalensis: take the powder of the aerial part of Scutellaria baicalensis, add 15 times the volume of water, ultrasonicate at room temperature for 30 minutes, centrifuge at 4000rpm for 10 minutes, collect the supernatant, repeat the above steps once for precipitation, and combine the above steps clear liquid to obtain the extract of the aerial part of Scutellaria baicalensis.

Abstract

The invention relates to application of an extract of an overground part of radix scutellariae in aquaculture. The overground part of the radix scutellariae comprises at least one of radix scutellariae stems, radix scutellariae leaves and radix scutellariae flowers. The extract of the overground part of the radix scutellariae has a good inhibiting effect on aquatic pathogenic bacteria, is not easyto cause drug resistance, and is suitable for large-scale application in aquaculture.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to the application of an extract of the aerial part of Scutellaria baicalensis in aquaculture. Background technique [0002] In recent years, with the continuous expansion of aquaculture scale, the increase of aquaculture species and the deteriorating environment, various aquaculture diseases have occurred frequently. Among them, aquatic animal bacterial diseases caused by aquatic pathogens are still the most common and harmful. One of the biggest diseases. [0003] However, on the one hand, the current research on antibacterial drugs is mainly aimed at pathogenic bacteria that often appear in terrestrial environments, such as Staphylococcus, Streptococcus, Escherichia coli, Candida albicans, Pseudomonas aeruginosa, etc. There are very few studies. Moreover, the antibacterial methods in aquaculture today are still mainly based on imitating human and veterinary medicines, lacki...
