Problems solved by technology

Existing single-type fish fertilizers and compound-type fish fertilizers also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, so they lack the effect of effectively preventing and controlling fish diseases
The microbial compound fish fertilizer can increase the content of beneficial bacteria in fish ponds and effectively reduce the occurrence of fish diseases. At present, there is no report on the special use of this compound microbial fish fertilizer

preparation example Construction

[0019] One of the objectives of the present invention is achieved through the following technical solutions: a feed for nanometer slow-release yellow catfish, characterized in that the raw material includes the following ingredients in weight ratio: 0.5-0.8 part of silicate bacteria, feces- A kind of feed of nanometer slow-release yellow catfish, it is characterized in that, this raw material comprises the composition of following weight ratio: 0.5-0.8 part of silicate bacteria, 1-3 part of streptococcus faecalis, 0.6-0.8 part of Trichoderma, marsh red pseudo 2-5 parts of single cell bacteria, 0.3-0.5 parts of yeast, 50-60 parts of fish bone meal, 65-70 parts of vinegar grain powder, 50-55 parts of waste liquid sediment, 40-60 parts of rice bran, 12-14 parts of brown sugar , 10-14 parts of salt, 80-85 parts of pig manure, 45-55 parts of pork slaughterhouse waste, 60-65 parts of aquatic plants, 12-16 parts of calcium bicarbonate, 14-17 parts of urea, 1-3 parts of iron citrate v...

Embodiment 2

[0028] The preparation method is the same as in Example 1.

[0029] In the juvenile stage of growth, pull out, divide and raise in the middle of five ponds, every pond 500, in four ponds, throw in the microorganism fish fertilizer of the embodiment 1 of the present invention and common fish fertilizer respectively according to the dosage of 200kg per mu (Contrast 1, produced by Beijing Century Ames Biotechnology Co., Ltd.), the other tank did not put fish fertilizer (control 2), but put in the same amount of ordinary fish food, and the rest of the feeding amount was the same, and the cultivation environment was the same. After 2-4 months of breeding, compare the yield and the growth status of the fish, and use the porous structure of hydroxyapatite to adsorb the fertilizer components in the inner grid of the carrier to achieve the purpose of slow release. Hydroxyapatite is also biodegradable, and the resulting degradation products are various trace element ions, which can be r...

Abstract

The invention discloses a nano slow-release feed for yellow-head catfishes. The feed comprises the following raw materials in parts by weight: 2-4 parts of bacillus subtilis powder, 1-4 parts of enzyme bacteria, 0.5-0.9 part of solid photosynthetic bacteria and 0.8-1.2 parts of bdellovibrio bacteriovorus. By adding a compound microorganism fertilizer, stichopus japonicus can be promoted to grow quickly, the EPA (eicosapentaenoic acid) content can be increased, the fish diseases are reduced, the fatality rate is reduced, meanwhile beneficial microorganisms in a water body are added, and the final quality is improved.

Description

technical field [0001] The invention relates to an aquaculture method, in particular to a feed for nanometer slow-release yellow catfish. Background technique [0002] Yellow catfish is a small freshwater economic fish. Although its individual is small, it is deeply favored by consumers because of its tender meat, delicious taste, rich nutrition, few thorns and no scales. At present, it has become one of the famous, special and high-quality breeding varieties with the most development potential. Breeding yellow catfish in rice fields is a production method that uses ecological principles to organically combine rice planting and aquaculture to achieve symbiosis of rice and fish and a double harvest of rice and fish. Existing single-type fish fertilizers and compound-type fish fertilizers also have a common shortcoming, that is, they cannot kill harmful bacteria and insects, and therefore lack the effect of effectively preventing and controlling fish diseases. The microbial...
