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

[0022] A method for preparing special compound microbial fish fertilizer for yellow catfish, which is characterized in that it comprises the following steps:

[0023] (1) Dry the aquatic plants to make the water content below 40%, cut them to 2-4cm, then add fish bone meal, vinegar lees powder, rice bran, brown sugar, salt according to the stated proportions, stir well, and mix well;

[0024] (2) Ferment the above mixture. The fermentation is aerobic composting. The fermentation water accounts for 20-30% of the total weight of the materials. The oxygen supply time is 50-60 hours in winter and 20-25 hours in summer. Fermentation temperature 45-60℃, fermentation time is 7-10 days;

[0025] (3) Mix the waste liquid sediment, pig manure, and pork slaughterhouse waste according to the stated proportions evenly, add yeast and streptococcus faecalis for fermentation; put the above substances into the pool to mix the rot, and cover the upper part with plastic The film is pre-fermented for 3...

Embodiment 2

[0031] The preparation method is the same as in Example 1.

[0032] In the juvenile stage of growth, they were fished out and fed into five tanks, each with 500 tanks. The microbial fish fertilizer and common fish fertilizer of Example 1 of the present invention were put into the four tanks at a rate of 200 kg per mu. (Control 1, produced from Beijing Century Arms Biotechnology Co., Ltd. ), the other pond does not put fish fertilizer (control 2), but put the same amount of ordinary fish food, the rest of the feed is the same, the culture environment is the same, after 2-4 months of cultivation, compare its output and the growth of the fish , As shown in Table 1 and Table 2:

[0033]

[0034]

[0035] Through the comparison of Table 1 and Table 2, it can be found that adding the compound microbial fertilizer of the present invention can promote the rapid growth of sea cucumbers, increase the EPA content, reduce fish diseases, and reduce sick and dead fish. At the same time, it...

Abstract

The invention relates to a method for cultivating Pseudobagrus fulvidraco in a rice field, particularly a stichopus japonicus fertilizer which comprises the following raw materials in parts by weight: 2-4 parts of Bacillus subtilis powder, 1-4 parts of ferment bacteria, 0.5-0.9 part of solid photosynthetic bacteria, 0.8-1.2 parts of bdellovibrio bacteriovorus, 0.2-0.6 part of vitamin additive, 10-16 parts of mineral additive, 0.2-0.4 part of chelator, 60-80 parts of hyacinth, 50-80 parts of edible fungus residue, 100-110 parts of vinasse, 40-60 parts of fishbone dust, 70-80 parts of rice bran, 10-16 parts of brown sugar, 45-55 parts of kongpo monkshood root, 40-50 parts of semen momordicae, 1-15 parts of Stellera chamaejasme and the like. A comparison shows that the composite microbial fertilizer can promote quick growth of stichopus japonicus, increase the EPA content, reduce the fish diseases and the amount of fish dying of illness, and increase the beneficial microbes in the water body, thereby enhancing the final quality and grade.

Description

Technical field [0001] The invention relates to a method for aquaculture, in particular to a method for breeding yellow catfish in a paddy field. Background technique [0002] Yellow catfish is a small commercial freshwater fish. Although it is small, it is favored by consumers because of its tender meat, delicious taste, rich nutrition, and few spines and scales. At present, it has become one of the famous, special and high-quality breeding species with the most development potential. The cultivation of yellow catfish in rice fields is a production method that uses ecological principles to organically combine rice planting and aquaculture to achieve rice-fish symbiosis and a double harvest of rice and fish. The existing single-type fish fertilizer and compound-type fish fertilizer also have a common shortcoming, that is, they cannot kill harmful bacteria and insects. Therefore, they lack the effect of effective prevention and control of fish diseases. The microbial compound f...
