Paralichthys olivaceus Chinese herbal medicine attractant and preparation method

Abstract

The invention discloses a paralichthys olivaceus Chinese herbal medicine attractant and a preparation method. The paralichthys olivaceus Chinese herbal medicine attractant is prepared from the following raw materials in parts by weight: 8-18 parts of medicated leaven, 7-15 parts of pericarpium citri reticulatae, 3-10 parts of fructus aurantii, 1-5 parts of anise, 1-5 parts of foeniculum vulgare, 5-10 parts of portulaca oleracea, 8-15 parts of cordate houttuynia and 3-11 parts of eclipta prostrata. The preparation method comprises the following steps: mixing the raw materials, decocting, filtering, concentrating and then obtaining the attractant through the spray drying technology. The medicated leaven, the pericarpium citri reticulatae, the fructus aurantii, the anise and the foeniculum vulgare in the attractant have traditional Chinese medicine fragrance, the palatability of the feed can be improved, and the gastric juice secretion, intestinal juice secretion and salivary secretion are promoted, and the absorption of the organism to the bait is strengthened; the portulaca oleracea contains niacin saponin, oxalic acid, vitamin A, vitamin B, vitamin C and tannic acid, has good attraction effect to the paralichthys olivaceus and has the effect of treating dysentery; the cordate houttuynia and the eclipta prostrate have strong fishlike smell to stimulate the taste bud of the paralichthys olivaceus so as to promote the feeding; furthermore, the cordate houttuynia has inhibiting effect on the microorganisms such as saccharomycetes and the like.

Description

technical field [0001] The invention relates to a food attractant for fish breeding, in particular to a flounder food attractant and a preparation method thereof, and belongs to the technical field of feed processing. Background technique [0002] Flounder (Paralichthys olivaceus ) is a cold-temperate benthic carnivorous economic fish. It has delicious taste, tender meat and high economic value. It is the main species of industrial farming in the north. In recent years, it has gradually developed in some areas in the south. , and gradually expanded in size. Flounder is a ferocious carnivorous fish. The natural larvae use invertebrate eggs and nauplii as bait. When they metamorphose, they start to eat cercarids. Later juveniles will only eat mysis, while juveniles and adults will mostly eat small fish, shrimps and shellfish. At present, there have been some studies on the requirements of flounder for protein, fat (including essential fatty acids), vitamins, and trace elemen...
