Problems solved by technology

Although the pellet feed solves the above problems, the large bait particles are not easy for sea cucumbers to absorb
After the pellet feed settles, sea cucumbers cannot be fed directly. After long-term soaking and decomposition, the water quality will be affected, and it is also not suitable for the growth and development of sea cucumbers.

Embodiment 1

[0021] 2000 g of kelp residue, 66 g of sargassum powder, 33 g of yeast powder, 33 g of sargassum powder, and 66 g of shell powder are used as raw materials, and 5% of microbial mixed bacterial liquid is added. The dry-wet ratio is 1:1, and the thickness of the material layer 15 cm, fermentation temperature 25°C, 4-5 days of fermentation, the fermented bait is dark brown, slightly sticky, and good in texture. After drying, it is crushed and passed through a 160-mesh sieve to obtain fermented bait. The output rate: 89.04%, protein content: 19.05%.

[0022] Cultivate 200-400 grams of juvenile ginseng and young ginseng in a 60L glass tank. The daily feeding amount is 3% of the fresh weight of sea cucumber. Feeding at night, the ratio of sea mud to bait is 3:1, and the daily water exchange amount is 3% of the cultured water body. 1 / 2, the culture temperature is 20-23 degrees, the culture time is 30 days, the growth rate of 30-day juvenile ginseng is 122%, and the growth rate of juv...

Embodiment 2

[0024] 6000 g of kelp residue, 400 g of sargassum powder, 200 g of yeast powder, 1400 g of sargassum powder, and 200 g of shell powder are used as raw materials, and 3% of microbial mixed bacterial liquid is added. The dry-wet ratio is 1:1, and the thickness of the material layer is 15 cm. , fermented at 25°C and fermented for 6 days to obtain a dark brown, slightly sticky, and good-quality fermented bait. After drying, it was crushed and passed through a 160-mesh sieve to obtain the fermented bait. The output rate: 89.04%, protein Content 19.29%.

[0025] Cultivate juvenile ginseng and 1 jin of young ginseng in a cement pond of 1 cubic meter, 670 juvenile ginseng and 65 juvenile ginseng. The daily feeding amount is 3% of the fresh weight of sea cucumber. Feed 1% in the morning, the ratio of sea mud to bait is 3:1, the daily water change is 1 / 2 of the culture water body, the culture temperature is 20-22 degrees, the culture time is 14 days, and the growth rate of juvenile gins...

Abstract

The invention relates to the biological fermentation technique, in particular to a manufacturing method of a fermented bait for a larval sea cucumber. The manufacturing method is characterized in that kelp residue, mixed microbial bacterial liquid, yeast powder, sargassum thunbergii powder, gulfweed powder and shell powder are uniformly mixed with proper water, and performed with solid fermentation at 20 to 35 DEG C for 2-6 days; and the solid fermented mixture was ground to obtain the microbial fermented bait for the larval sea cucumber. The production steps are as follows: burdening, mixing, solid fermentation and grinding. According to the invention, the microbial bacterial liquid is taken as the microbial zymocyte that generates rich nutrient substances during metabolic process, mainly including substances for promoting biological production such as biological small peptide, amino acid and polysaccharide. The bait can improve metabolic function of larval sea cucumber intestines and stomach, enhance immunity of the larval sea cucumber, reduce diseases, accelerate the growth rate of the sea cucumber and improve the breeding water quality. The method is simple in technique and easy to operate. The raw material is low in cost; and the product quality is good.

Description

technical field [0001] The invention relates to biological fermentation technology, in particular to a production method of fermented young ginseng bait. Background technique [0002] With the vigorous development of the sea cucumber artificial breeding industry, the research on the digestive physiology and nutritional requirements of sea cucumbers has also begun. The research on the digestive enzymes in sea cucumbers has prompted the development of artificial bait for sea cucumbers, which has promoted sea cucumber seedlings and aquaculture industries to some extent. development of. However, with the further development of the sea cucumber aquaculture industry, various algal resources as the main body of artificial bait are increasingly scarce, and their prices have risen sharply, resulting in a significant increase in the cost of artificial bait for sea cucumbers. [0003] Sea cucumber intestines contain many digestive enzymes and microorganisms, which are helpful for the...
