Microbial fermentation feed for procambarus clarkia and preparation method of feed

The invention provides microbial fermentation feed for procambarus clarkia. The feed comprises the following components: soybean meal, bean dregs, vegetable cake, corn meal, fish meal, kelp meal, an attractant, a microbial strain and microelements, wherein the attractant contains betaine and squid visceral powder, the microbial strain includes at least one of bacillus subtilis and bacillus amyloliquefaciens and aspergillus niger, and the microelements include iron, manganese, zinc, silicon, cobalt and boron. The feed has a reasonable formula, is rich in various nutrient ingredients such as protein, amino acids, vitamins, minerals and unsaturated fatty acids, and can effectively meet the growth needs of the procambarus clarkia, and microorganisms in the feed can hydrolyze organic matter ina water body through the own metabolic activities, thereby achieving the purpose of purifying water. 本发明提出了一种小龙虾微生物发酵饲料，包含以下组分：豆粕、豆渣、菜饼、玉米粉、鱼粉、海带粉、诱食剂、微生物菌种以及微量元素，其中，诱食剂包含甜菜碱和鱿鱼内脏粉，微生物菌种包括枯草芽孢杆菌和解淀粉芽孢杆菌中的至少一种以及黑曲霉，微量元素包括铁、锰、锌
