A multi-strain compound fish bait is characterized in that the bait is composed of a solid-state fermented basal ration and Bacillus subtilis, and the basal ration without solid-state fermentation contains 55% to 60% by weight of plant Oil meal, the vegetable oil meal is composed of soybean meal, cotton meal and rapeseed meal with a weight ratio of 1:0.5-0.7:0.5-7, the ratio of Bacillus subtilis to basal diet is 10 6 to 10 7 CFU/g, solid The preparation method of the fermented basal ration is as follows: 1) the blue pear head mold and the rhizopus are respectively cultivated and made into a bacterial suspension; 2) after the vegetable oil meal is pulverized, the two bacterial suspensions are fully mixed with the vegetable oil meal Mix and adjust the water content of the vegetable oil meal to 35%-45%, put it at 24°C-26°C for solid-state fermentation for 60h-72h, mix the remaining components of the basic diet with the solid-state fermented vegetable oil meal, and place Solid state fermentation at 20°C-22°C for 36h-48h. |
