Description

Soil pick-up device of pond is bred to big loach land-based cask Technical Field The utility model relates to the technical field of fishery cultivation, in particular to a sewage suction device of a land-based drum cultivation pond for large thorn loaches. Background With the maturation of artificial cultivation technology of the large-thorn loaches, people start to try to cultivate the large-thorn loaches in the land-based cultivation pond, compared with the traditional fishpond, the land-based cultivation pond can realize an intensive cultivation mode, land, water source and cost are saved, meanwhile, water quality can be better controlled, disease control is enhanced, and the like. In the breeding process of the large-thorn loaches, the bottom of the pond is easy to have sundries such as residual fish food and feces, the large-thorn loaches are fish which like at the bottom, the large-thorn loaches are fish without swim bladder, diseased fish and just dead fish can not float on the water surface, and are not easy to perceive when diseases occur, so that people design a device capable of sucking up dead fish, for example, an energy-saving fish pond capable of automatically and rapidly discharging sewage and cleaning dead fish, disclosed in China patent with the application number 202022035621.7, comprises a fish pond bottom surface, fish pond side walls, a dead fish cleaning device and a quick-discharge anti-overflow mechanism, and the dead fish cleaning device is provided with an anti-blocking assembly.
