Problems solved by technology

Therefore, theoretically, seaweed residues have also been used as feed additives, but because the crude fiber content is as high as 28.80%-35.76%, direct feeding is difficult to digest and absorb, so it is not suitable for direct use in aquaculture bait, and must try to reduce the crude fiber in seaweed residues content

Abstract

The invention discloses a method used for reducing alga residue coarse cellulose content. The method comprises following steps: alga residue is fully mixed with a hydrochloric acid solution, reaction is carried out for 30min, and pH value is controlled to be 6 to 7 so as to obtain an alga residue pretreatment product; the alga residue pretreatment product is inoculated with a composite microbial preparation for solid-state anaerobic fermentation. According to the method, alga residue is subjected to microecological degradation, alga residue coarse fiber is reduced via synergistic metabolism effect of microorganisms, degradation of proteins which are difficult to be digested is realized, polysaccharides are converted into monosaccharides and oligosaccharides, plant proteins are converted into bacterial proteins, integral improvement is realized, and it is more beneficial for absorption and utilization by fish and shrimp.

Description

technical field [0001] The invention belongs to the technical field of seawater culture bait production, and relates to a method for reducing the crude cellulose content of seaweed residue. Background technique [0002] According to statistics, my country's annual output of aquatic products in 2014 was 64.6152 million tons, of which the output of aquaculture aquatic products was 47.4841 million tons, accounting for 73.49% of the total aquatic products in the country and more than 60% of the total amount of aquaculture aquatic products in the world. Large aquaculture countries where farmed production exceeds capture production. As the material basis for the development of the aquaculture industry, the aquatic compound feed industry has entered a period of rapid development with the rapid development of the aquaculture industry, and has become a sunshine industry with the fastest growth, the best benefits, and the greatest potential in the feed industry.
