Organic river crab bait additive and organic river crab compound feed

Abstract

The invention discloses an organic river crab bait additive. The bait additive comprises the following components in parts by weight: 70-80 parts of natural Chinese herbal medicines, 5-15 parts of yeasts, 5-15 parts of apatite,1-5 parts of vitamin C and 1-5 parts of betaine, wherein the natural Chinese herbal medicines are selected from one or more of isatis root, carpet bugle, astragalus and rheum officinale. The invention further discloses an organic river crab compound feed containing the organic river crab bait additive. When the organic river crab bait additive disclosed by the invention is used for preparing feed, chemically synthesized substances, antibiotic drugs, parasite drugs or other synthesized drugs can be avoided, and the produced feed is true organic feed. When the organic river crab compound feed disclosed by the invention is used for feeding, in an organic crab cultivation process, nutrient needs can be balanced, diseases can be prevented and treated, healthy molting can be ensured, crabs can be prevented from killing each other, and environment pollution of aquatic water can be avoided.

Description

technical field [0001] The invention relates to an organic river crab bait additive and an organic feed for aquaculture, and in particular to an organic bait additive and an organic bait formula used in the adult crab breeding stage (from harvesting crabs to grown commercial crabs). Background technique [0002] Organic food has been adopted as the highest level of pollution-free food in developed countries and is leading the consumption trend; in my country, the concept of organic food is being accepted and recognized by domestic consumers. In the production and processing of organic food, it is stipulated that the use of synthetic substances such as chemical fertilizers, pesticides, and chemical preservatives is prohibited, and the use of genetic engineering and its products is also prohibited. The farming of aquatic products in foreign countries has entered the era of organic farming, and organic farming standards are adopted in the breeding process, that is, chemical syn...

AI Technical Summary

Problems solved by technology

The currently promoted and used pollution-free breeding technology standard is to selectively use drugs for prevention and control. During the disease prevention process, the drug resistance of pathogenic bacteria will still be enhanced, resulting in a decline in the immunity of the crab body, making it difficult to effectively control the disease.

[0004] Although the compound feed sold on the market has a certain effect on the growth, precocious puberty and disease prevention of river crabs, the compound feed uses artificially synthesized chemical additives that are prohibited in the production process of organic farming. The feed cannot be called organic. It is impossible for the bait to obtain the organic certification of the Organic Food Certification Center (OFDC) of the State Environmental Protection Administration, and it is impossible to sell the crabs grown there as organic food.
