Embodiment 1

[0049] Embodiment 1, get Acanthopanax, put in the continuous reflux extractor, add 75% ethanol of 7 times of amount, add continuous reflux extraction, until getting extracting liquid 1ml, add the ethanol solution of 10% α-naphthol and do not show reaction till . The extract is concentrated into 5% extract, and then dried into powder for future use. The above-mentioned powder is added to fish feed in a certain proportion, and it can be used after being made into granules.

Embodiment 2

[0050] Embodiment 2, the roots and stems of Acanthopanax senticosus were first stirred and extracted with 5-7 times the amount of 90-100° C. water for 3-5 hours, 2-3 times, and then extracted with 0.5N NaOH. Combine the two extracts, remove the residue, add ethanol to the supernatant to 80%, precipitate to obtain crude Acanthopanax extract, or further dry it into powder, which can be added to fish feed in an appropriate proportion for use . The ethanol-containing supernatant can be refluxed for reuse.

Abstract

The present invention provides a application od acanthopanar root in aquatic culture. Proper dosage of acanthopanar root extractive has the functions of strengthening the immunologic system, especially the non-specific immunity, raising the resistance to various pathogenic diseases and raising survival rate of fishes cultured in fresh water or sea water. In addition, acanthopanar root extractive has also the function of raise the irritability resistance to fishes and thus the environment stress adapatability. Acanthopanar root and its extractive is one non-toxic, harmless and pollution-less feed additive.

Description

technical field [0001] The invention relates to a fish feed additive, and more specifically relates to the application of Acanthopanax senticosus in aquaculture, which is used as a fish immune enhancer to improve the disease resistance of fish. Background technique [0002] With the development of aquaculture industry, the disease of farmed animals has become a prominent problem restricting the development of this industry. As far as infectious diseases are concerned, their types are very complex, including bacterial diseases, viral diseases, parasitic diseases and fungal diseases. At present, there are mainly the following measures for the prevention and treatment of farmed fish diseases: ecological control; drug control; vaccination. [0003] Among these measures, the role of ecological control is very limited, and it is often difficult to achieve; although drug control technology is relatively effective and is the main method currently used, its ...
