Modern aquatic product feed suitable for larva stage of giant salamander and preparation method of modern aquatic product feed

Abstract

The invention discloses a modern aquatic product feed suitable for a larav stage of a giant salamander. The feed comprises the following raw materials: 65-75wt% of components A and 25-35wt% of components B, wherein the components A comprise water earthworms, diplopods, freshwater shrimps, shrimps, silkworm chrysalis, chironomus larvas, bean worms, maggots, slugs, moina, loaches, pelteobagrus fulvidraco fries and salangid; and the components B comprise fish meal, fermented peanut meal, soyabean protein powder, snail meat, scallop meat, clam meat, cod-liver oil, vitamins, minerals, sodium alginate, endothelium corneum gigeriae galli, Chinese yam, medicated leaven, poria cocos, dried orange peel, licorice roots, Chinese angelica, honeysuckle and Chinese thorowax. The invention further discloses a preparation method of the modern aquatic product feed suitable for the larva stage of the giant salamander.

Description

technical field [0001] The invention relates to the technical field of aquatic feed, in particular to a modern aquatic feed suitable for giant salamander larvae and a preparation method thereof. Background technique [0002] Giant salamander, commonly known as giant salamander, is a national second-class protected animal. Its meat is delicious, but artificial breeding has always been difficult. Among them, the larvae of giant salamanders mainly feed on red nematodes, small fish and shrimps, water fleas and aquatic insect larvae. Feed is a feeding method, but there are many defects in the feed of this feeding method: 1. Natural food organisms are easily affected by natural resource fluctuations and seasonal climate changes, such as abundant sources in a certain period and relatively scarce in another period; 2. The immature production technology makes the production cost higher, and the output and quality are difficult to control; 3. The nutrition is single, the composition ...

Its meat is delicious, but artificial breeding has always been difficult. Among them, the larvae of giant salamanders mainly feed on red nematodes, small fish and shrimps, water fleas and aquatic insect larvae. Feed is a feeding method, but there are many defects in the feed of this feeding method: 1. Natural food organisms are easily affected by natural resource fluctuations and seasonal climate changes, such as abundant sources in a certain period and relatively scarce in another period; 2. The immature production technology makes the production cost high, and the output and quality are difficult to control; 3. The nutrition is single, the ingredient distribution is unreasonable, and the cost is too high

However, it has been found in practice that this soaking treatment method has many disadvantages: 1. The residual disinfectant is serious, which cannot meet the requirements for green cultivation of giant salamanders; Kill the pathogenic bacteria infected in the fish and shrimp; 3. Long-term use of disinfectants will cause the pathogenic bacteria to develop drug resistance. Only by continuously increasing the dosage of the drug can the bacteria be killed; Injured fish and shrimps may even be fatal, which will increase the cost of farming
