The two partition plates are fixed between the filter plate and the bottom wall of the shell. When the fish tank is used, excrement of small fishes is accumulated on the upper portion of the filter plate, at the moment, a one-way absorption mechanism works and drives an absorption head to absorb the excrement of the small fishes, meanwhile, a two-way rotating mechanism drives the absorption head to do reciprocating circular motion on the upper portion of the filter plate, and a linear driving mechanism drives the absorption head to do linear motion; the diameter of the circular motion of the absorption head is changed continuously, so that the universality of the absorption range of excrement of small fishes is guaranteed, then the excrement of small fishes is conveyed to the plant root system part in a planting cavity, and decomposition and absorption of the excrement of small fishes by plants are accelerated.

The invention discloses a fishing device, which comprises a resistance measuring device and an expanding device. The resistance measuring device is provided with two fixed electrodes, and the optimalsetting of the standard value should be greater than the resistance value of the water but less than the resistance value of the freshwater fish body. The expanding device expands when the resistancebetween the two electrodes is measured at a standard value. The fishing device is covered with bait, and the device can single out the bigger fish depending on the size-setting of the device in principle. The smaller fish cannot swallow the device; whereas the bigger ones can swallow the device and make the balloon expand in the body due to fact that the resistance value of fish body is far less than that in water. As the balloon expands in the fish body, the size of fish is increased, and the fish belly is upwards and floats out of the water surface. The device uses a single chip control. Theenvironment-friendly sustainable fish farm adopts the said fishing device to achieve sustainable fishing. The fishing device has the advantages of easy operation and less manpower input without accidentally injuring fry. The fishing device also innovates a new idea of fishing that is feasible for sustainable batch fishing.
