Leech bait

Abstract

The invention relates to the field of feeds, and in particular relates to a leech bait. Saccharides, protein, plant fibers, microelements, multivitamins and the like are fused in various growth periods of leech; research on an artificial feed has achieved initial success; the artificial feed can meet the nutrient requirements of the leech at different growth stages, and is easy to absorb; standardized breeding is achieved; the feed is fed without residues; a water source is not polluted; and the storage is facilitated.

Description

technical field [0001] The invention relates to the field of feed, in particular to a leech bait. technical background [0002] Leeches, annelids, are traditional medicinal aquatic animals in my country. Their bodies contain an anticoagulant substance [hirudin], which has special effects on the treatment of cardiovascular and cerebrovascular diseases and anti-cancer. With the increasing medicinal value of leeches In-depth development, its market demand potential is huge, but the lack of wild leeches is far from being able to meet the huge supply demand in the market, so artificial breeding is urgently needed to fill the huge supply gap in the market. [0003] To raise leeches, we must first solve the food problem of leeches. In nature, leeches mainly feed on snails. If we only feed snails in the process of artificial high-density breeding, it is very undesirable. Leeches suck the viscera of snails, while the shell and meat If some cannot be solved, it will definitely cause a...

[0002] Leeches, annelids, are traditional medicinal aquatic animals in my country. Their bodies contain an anticoagulant substance [hirudin], which has special effects on the treatment of cardiovascular and cerebrovascular diseases and anti-cancer. With the increasing medicinal value of leeches In-depth development, its market demand potential is huge, but the lack of wild leeches is far from being able to meet the huge supply demand in the market, so artificial breeding is urgently needed to fill the huge supply gap in the market

[0003] To raise leeches, we must first solve the food problem of leeches. In nature, leeches mainly feed on snails. If we only feed snails in the process of artificial high-density breeding, it is very undesirable. Leeches suck the viscera of snails, while the shell and meat If some cannot be solved, it will definitely cause a lot of waste. If it is not managed properly, it will also cause the survival rate of snails. Many reasons lead to the utilization rate of snails being less than 20%, and the leftover food that has not been eaten will definitely cause damage to the breeding water. Serious pollution, producing a large amount of ammonia nitrogen, hydrogen sulfide, nitrite and other harmful substances

Destroy the ecological balance of the water body, promote the proliferation of harmful bacteria, which is very likely to cause various infectious diseases, and bring immeasurable economic losses to farmers
