Embodiment Construction
[0019] Describe above-mentioned invention process (by 100kg feed preparation) below in conjunction with embodiment.
[0020] 1. Selection and activation of fermentation strains
[0021] According to the nutritional composition of the fermentation base material and the tropism and complementarity of different strains, the fermentation strains consist of Rhizopus, Trichoderma, Saccharomyces cerevisiae, Bacillus subtilis, and lactic acid bacteria, which were purchased from China General Microorganism Culture Collection Center (Beijing) , after amplification, the density of each strain was 1×10 9 ~2×10 11 CFU / g.
[0022] Preparation of fermented bacteria liquid: Boil 1000g of clean fresh water, cool down to 30°C, put into a clean container, add 40g of brown sugar, 10g of salt, 40g of flour, and then add Rhizopus, Trichoderma, Saccharomyces cerevisiae, Bacillus subtilis, and lactic acid bacteria. 0.1 g was mixed evenly, left to ferment for 2 hours, and the bacterial liquid f...

Abstract
A preparation method of stichopus japonicus fermented feed capable of replacing alga is prepared by taking water caltrop, hydrilla varticillata, water hyacinth, aggregation of grass, alfalfa and common seepweed herb as the alga replacing raw material and additionally adding four, sea mud, multi-vitamin, fish meal, mussel powder, bean pulp, earthworm powder and zeolite powder with the steps of: drying all materials till the water content is less than 12%, and crushing to be 60 meshes, so as to obtain a fermentation substrate; mixing water, brown sugar, table salt and flour, adding rhizopus, trichoderma, saccharomyces cerevisiae, bacillus subtilis and lactic acid bacteria, mixing uniformly, standing and fermenting for 2h, so as to obtain a feed fermenting bacteria solution; and inoculating the fermentation substrate according to the ratio of 0.4% to 0.5% at the environment temperature of 25 DEG C to 30 DEG C, carrying out solid fermentation, and then drying and crushing, thereby obtaining the stichopus japonicus fermented feed. The preparation method has the advantages that the raw material source is stable, the cost is low, the process is simple and east to operate, and a great significance is provided in reducing culture cost of stichopus japonicas, maintaining an ecological environment, reasonably using idle resource and prompting the health sustainable development of stichopus japonicu culture industry.
Description
technical field [0001] The invention belongs to the field of aquatic feed. Specifically, it relates to a method for preparing sea cucumber fermented feed which can replace seaweed by using land forage grass and freshwater plants as feed to replace limited seaweed resources such as sargassum and sargassum and treating with microorganisms. Background technique [0002] With the rapid expansion of sea cucumber farming scale, feed has become one of the bottlenecks restricting sea cucumber farming. The raw materials of conventional japonicus feed are mainly composed of fish meal, soybean meal, seaweed, sea mud and so on. Due to marine pollution, overuse and other factors, resources such as sargassum are nearly exhausted, resulting in high price of sea cucumber feed and uneven quality. At the same time, the raw materials of japonicus japonicus feed mainly come from the sea, which is in the same environment as japonicus japonicus, and sometimes it is not handled properly, whi...
