PROBLEM TO BE SOLVED: To provide a culture pond-cleaning apparatus which can clean a culture pond without using a large labor but only by an initial investment to improve the states of conventional culture bond-cleaning means which are used spread, e.g. zeolite or the like, on the bottom of a culture pond, wherein the zeolite must be replaced for each pond-drying work to give the large burdens of zeolite purchase cost and replacement labors to culture contractors, can sufficiently clean the culture ponds even by the means, and give the troubles of stenches and sludge accumulations to the culture contractors. SOLUTION: The culture pond-cleaning apparatus includes a water-activating device and a water ejector combined, and can efficiently supply oxygen to the culture pond to help the cleaning of the culture pond and the growth of cultured fish.
