Embodiment 1

[0009] Example 1: Feasibility of replacing live bait with artificial compound feed

[0010] The formula of artificial compound feed used in the experiment is: 20% of eggs (by dry weight), 26% of beef liver (by dry weight), 20% of fish meal, 3% of shrimp meal, 13% of soybean meal, 8% of flour, 6% of bran %, mussels (dried mussels) 3%, inorganic salts and vitamins, etc. 1%. Two kinds of swordtail fish were selected, and the water earthworm group was used as the control. From the perspective of growth rate, the feeding effect of artificial compound feed is worse than that of water earthworms, especially in the larval stage, the difference is more obvious, but the gap between the two becomes smaller in the later stage of the experiment. In the two groups of experiments, there was no significant difference in the survival rate between the experimental fish and the control fish. The development of the ovaries of the experimental fish and the control fish was dissected and compared...

Embodiment 2

[0012] Embodiment two: the improvement of the artificial compound feed of swordtail fish

[0013] 1. Improved formula of artificial compound feed:

[0014] Fish meal: 30%, flour: 12.5%, soybean meal: 20%, fresh egg: 10%

[0015] Shrimp: 10% Mussels: 5% Fresh pork liver: 10% Inorganic salt: 1%

[0016] Multivitamin: 0.5% Choline Complex: 0.5% VE: 0.25% VC: 0.25%

[0017] The improved formula contains 30% imported white fish meal, providing enough high-quality protein sources for the growth, development and reproduction of swordtail fish; adding 5% mussels (dried mussels) and 0.25% vitamin E to promote gonads Development, improve the fecundity of swordtail fish; in addition to adding 0.5% of multivitamins, 0.5% of choline complex is also added to promote fat metabolism of swordtail fish and reduce fat accumulation.

[0018] Two, the preparation of swordtail artificial compound feed has the following steps:

[0019] (1) Selection of raw materials

[0020] Fishmeal: Imported ...

Abstract

The present invention relates to a xiphophorus feed formula and process for preparing xiphophorus feed by using said formula. Said formula uses fish powder, flour, soybean flour, fresh egg, fresh shrimp, mussel and fresh pork liver as raw material, and adds a certain quantity of inorganic salt and composite vitamin. Said invention also provides the concrete steps of said process for preparing said xiphophorus feed.

Description

technical field [0001] The invention relates to a swordtail fish feed formula and its preparation, which is suitable for the fields of pure line cultivation of swordtail fish and the like. Background technique [0002] Swordtail fish is a small tropical fish. Due to its small size, short reproductive cycle, strong fecundity and easy breeding in the laboratory, it is sensitive to various pesticides, heavy metals and other poisons, and is highly sensitive to certain fish pathogens. Blindness, deformity and many other mutant traits often appear, so it is suitable as an animal model. Since 1987, the Pearl River Fisheries Research Institute of the Chinese Academy of Fishery Sciences has carried out the directional breeding of swordtail fish and related experimental animal research work, and has carried out nearly 20 years of pure-line selection research on the aquatic experimental animal swordtail fish . [0003] In the early stage of directional cultivation, swordtail fish wer...
