description The invention provides a method for improving the transparency of a eutrophic water body by utilizing weever, daphnia pulex and freshwater mussel, belonging to the field of ecological restoration of awater body. The method comprises the following steps: putting weever and freshwater mussel into the eutrophic water body, and after a week, putting daphnia pulex into the eutrophic water body, wherein the daphnia pulex is fed on particles including algae and organic detritus in the water body; the weever catches and is fed on wild trash fishes to reduce feeding of the wild trash fishes to the daphnia pulex; the freshwater mussel is fed on particles like algae and manure of the daphnia pulex and the weever in the water body by filtering; thus, the transparency of the water body is improved. The method provided by the invention has the advantages of fast action, safety, durability, etc., and has important practical significance on improvement of the transparency of the eutrophic water body. 本发明提供了种利用鲈鱼、蚤状溞和河蚌提高富营养水
