The invention provides fermented straws, which are prepared by fermenting a leavening agent for activating microorganism growth and crop straw powder, wherein the leavening agent comprises the following components in percentage by weight of the total weight of the leavening agent and the crop straw powder: 0.02-0.03% of cyromazine, 0.2-0.4% of copper sulfate, 0.6-0.8% of zinc sulfate, 0.3-0.6% of ferrous sulfate, 0.6-0.7% of cobalt chloride, 0.1-0.2% of edible salt, 0.3-0.4% of baking soda and 0.5-1.5% of glucose powder. The invention also provides an aquaculture feed composition comprising an aquaculture feed base and the fermented straw. The fermented straw contains a large amount of beneficial floras such as lactic acid bacteria and the like, and can be used as a culture water body purifying agent. The aquaculture feed composition is used as a feed, is an ecological and environment-friendly feed, and is low in manufacturing cost. |
