Fertilizer and water type bait for aquaculture and preparation method thereof

Abstract

The invention discloses a fertilizer and water type bait for aquaculture and a preparation method thereof. The fertilizer and water type bait is prepared by the following materials in parts by weight: 10 to 80 parts of special organic fertilizer, 0.8 to 20 parts of auxiliary materials, 1 part of fermenting agent, and 2-20 parts of microalgae. The fertilizer and water type bait has the advantages that the special organic fertilizer for aquaculture is prepared by the fermentation of chicken manure, duck manure, pigeon manure and other auxiliary materials through the biological fermentation technique, and aims at the problems of shortage of existing state protein feed resources, a large feeding amount of aquaculture protein feed, high cost, easy pollution to culture water by remained feed and manure of aquatic animals, and the like; the organic fertilizer can be fed to the aquatic animals or be used as the culture medium to culture diatom and spirulina in an oriented way in the aquaculture process, the harmful matters in water are converted into the harmless sub-structure, and a large amount of oxygen is released, so that the culture water is purified, a large amount of foods is provided for the cultured animals, and the feeding amount of protein feed is reduced.

Description

technical field [0001] The invention belongs to the fields of resource environment and biotechnology, and in particular relates to a kind of fertilizer and water type bait for aquaculture and a preparation method thereof. Background technique [0002] Protein resources are the foundation of the feed industry, and the shortage of protein feed has become a prominent problem in the development of the feed industry. At present, the domestic feed demand is 150 million tons per year, and about 37.5 million tons of protein raw materials are needed, 70% of which depend on imports. Not only that, with the development of the feed industry, the demand for protein raw materials also increases proportionally. [0003] Spirulina and diatoms are aquatic feed additives with high protein and amino acid content and rich nutrition. They can replace traditional protein feeds when used in large quantities. Spirulina can improve the survival rate of aquatic animals, enhance immune function, and ...

Problems solved by technology

[0005] Aiming at the current shortage of protein feed resources in my country and the problems of high cost and high cost of protein feed in aquaculture, and the fact that residual feed and aquatic animal excreta are likely to pollute the aquaculture water, the present invention provides an aquaculture fertilizer and water type bait and a preparation method thereof , fermenting chicken manure, duck manure, pigeon manure and other auxiliary materials through biological fermentation technology to prepare a kind of fertilizer and water type bait for aquaculture. Algae, which convert harmful substances in water into harmless substructures and release a large amount of oxygen, purify the aquaculture water and provide a large amount of food for aquaculture animals at the same time, reducing the input of protein feed
