Seasonal dynamics of their quantity is shown under conditions of the Dnieper basin water bodies. Besides Rotatoria species confined to Astacidae representatives of the Rotatoria, Cephalodella, Lecane and others who usually lead a free mode of life were found in the Astacidae gill cavity. It is stated that during ecdysis of Astacidae there are no rotifers in their cavity.
