Chinese herbal medicine feed attractant for freshwater fishes and preparation method of feed attractant

Abstract

The invention discloses a Chinese herbal medicine feed attractant for freshwater fishes and a preparation method of the feed attractant. Tangerine peel, common aucklandia roots, cloves, common onion bulbs and wild mint herbs are effectively matched, the prepared Chinese herbal medicine feed attractant is processed into particles, feeding attraction is performed by the aid of a labyrinth, the Chinese herbal medicine feed attractant particles are bitten and pecked for 4.88-5.52 times every minute within 90 minutes, the particles are fed for 3 times every day, and the weight gain rate of the freshwater fishes after 40 days is 49.22-51.39%. A spring rod and a limit pad drive a sieve plate to vibrate, screening of crushed raw materials by a screen mesh is effectively promoted, water added intoa tank can be screened by the aid of a water pipe and a diversion plate, so that the crushed raw materials can collect powder, and the Chinese herbal medicine feed attractant solves the technical problems that powder of crushed Chinese herbal medicines is not easily collected, and screening effects are poor in the screening process in the prior art.

Description

technical field [0001] The invention relates to the technical field of preparation of a Chinese herbal food attractant, in particular to a Chinese herbal food attractant for freshwater fish and a preparation method thereof. Background technique [0002] With the development of fish farming and feed industry, it is very necessary to add food attractant to the bait. Adding bait attractants to feed farmed fish can effectively promote the fish's food intake and increase food intake, thereby improving the utilization efficiency of the feed; promoting the fish's preference for the bait, reducing the bait coefficient, reducing water pollution, shortening the The production cycle can improve the efficiency of fish farming; the use of food attractants can make fish better use raw materials such as plant proteins that they don't like to eat, which is conducive to the development of new feed resources and reduces feed costs. Chinese herbal medicine is natural, has no toxic side effect...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of Chinese herbal medicine food attractant and preparation method thereof for freshwater fish, solve the following technical problems: (1) Chinese herbal medicine food attractant prepared by carrying out effective proportioning of tangerine peel, woody fragrance, clove, onion, mint The food-inducing agent is processed into granules, and a maze is used to attract food. The number of bites and pecks per minute of the Chinese herbal food-attractant granules is 4.88-5.52 times per minute, and the bait is fed 3 times a day. The weight gain rate of freshwater fish after 40 days is 49.22-51.39 %, solve the technical problem that the effect of Chinese herbal medicine attractant is not good, and the weight gain effect of freshwater fish is not obvious; (2) drive the second pulley to rotate through the output shaft of the drive motor, and the second pulley drives the first One pulley rotates, the first pulley drives the second bearing rod to rotate, the second bearing rod drives the first bearing rod to rotate through two meshing gears, the first bearing rod and the second bearing rod drive the crushing roller on the surface to crush the raw materials , to solve the technical problem that the crushing efficiency of the raw material crushing device of Chinese herbal medicine is not high, and the device structure is complex and the economy is not high; For the screening of raw materials, through the setting of water pipes and drainage plates, water can be added to the screening tank, so that the pulverized raw materials can be collected as powder, which solves the problem that the pulverized powder of Chinese herbal medicine is not easy to collect in the prior art.
