Abstract
The utility model discloses a stepped-type fish farm, which comprises a plurality of square fishponds arranged side by side in a stepped manner from high to low. Every two adjacent fishponds share a single pond dam and the pond dam is provided with a water passage for communicating the two adjacent fishponds with each other, wherein the water passage is provided with a gate and a blocking net. When the water in a relatively higher fishpond overflows the pond dam of a relatively lower fishpond adjacent to the relatively higher fishpond, a waterfall-shaped water flow is formed. The oxygen content of the water flow is increased when the water flow is in fully contact with the air. In this way, even when the water flow is small, the oxygen content of water in all the fishponds of the entire fish farm can be ensured. According to the technical scheme of the stepped-type fish farm provided by the utility model, not only the structure of an original fish farm is simplified, but also the oxygen content of water in the fishponds is increased. Therefore, the efficient fish culture in running water can be realized by means of a small-flow water source.
