Embodiment

[0033] 1. At the seedling stage, 10,000 seedlings are counted: 100 grams of fermented worm-soluble pulp per meal, fed three meals, increasing the amount by 10% every day, and then fed with powder after ten days in a row; directly diluted with water, sprinkled in the whole pond .

[0034] 2. Breeding period: replace 15%-20% of feed, add appropriate amount of water to dissolve and mix with feed.

[0035] 3. Feeding table time: eat the granular material within 40-50 minutes, because 15%-20% of the present invention is soluble in water, and can be absorbed and digested by aquatic seedlings; if the weather changes, the feeding can be suspended, and the amount of sewage discharge and water exchange should be controlled within 10%-20%.

[0036] 4. In case of white stools and liver atrophy caused by digestive overload and toxins, you can sprinkle 5 grams per cubic meter of water, 3 times a day, and use it continuously for 3-5 days. Reduce the feed by half or suspend feeding, and grad...

Abstract

The invention discloses a microbial fermentation method for preparing insect soluble pulp from hermetia illucens larvae. The method comprises the following steps: beating hermetia illucens old maturelarvae into fresh insect pulp; adding 0.5% of high-activity compound bacteria into the fresh insect pulp; and carrying out fermentation and enzymolysis composite reaction at 30-35 DEG C to prepare fluid insect soluble pulp. The method has the advantages that: scientific matching is achieved, the insect soluble pulp is close to natural bait, a foundation is laid for providing a healthy body for aquatic products in the whole process, the survival rate is increased, and the bait falling coefficient is low; high-quality amino acid is rapidly supplemented and absorbed and is a substitute raw material for crude protein coating, digestive enzyme conversion is not needed, the liver load is reduced, and the liver atrophy phenomenon is eliminated; and the water quality is stabilized, the water quality is not polluted, algae pouring is not easy, the heavy water color does not need to be worried too much, and zymophyte organic acid has a certain detoxification effect on algae, nitrite, hydrogen sulfide, chloride ions and the like.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a microbial fermentation method and application of using black soldier fly larvae to prepare insect-dissolved pulp. Background technique [0002] Black soldier flies belong to Diptera, insects of the Soldier family, and have become insects distributed worldwide. Black soldier flies larvae feed on decaying organic matter and animal feces in nature, which can inhibit the production of odor, reduce the number of harmful bacteria and control The breeding of houseflies can realize the resource reuse of kitchen waste and livestock and poultry manure. Black soldier fly larvae contain a lot of protein and fat, and can be used to produce animal feed with high economic value. It is a resource insect with great application prospects. It has been reported that it can replace fish meal and soybean meal for chicken, pig and aquatic products. [0003] The fresh black soldier flies cannot ...
