Ecological prawn residual feed pollution control device

Abstract

The invention relates to an ecological prawn residual feed pollution control device. The ecological prawn residual feed pollution control device comprises a buoy (1), a wing (2) and a mesh cage (4), wherein the buoy (1) is arranged on the top of the device and is used for lifting and spreading the whole device by means of the buoyancy of sea water, the wing is connected between the buoy (1) and the mesh cage (4), prawn feed is thrown into water from holes of the wing, and the mesh cage (4) comprises a feed tray (3), a middle tray (5) and a bottom net tray (7). According to the ecological prawn residual feed pollution control device, pollution, caused by residual feed, to organic materials in a prawn pond is effectively relieved through reduction of the residual feed pollution area, repeated use of the residual feed and a biological stereoscopic aquaculture method.

Description

technical field [0001] The invention relates to an ecological control device for shrimp residual bait pollution. Background technique [0002] As we all know, in the current process of shrimp pond culture, extensive and excessive feeding methods are mostly used, and excessive feeding is the main reason for the deterioration of water quality and bottom environment in shrimp pond culture areas, and has a negative impact on pond bottom quality and water bodies. Continuous organic pollution is produced, and the treatment of aged shrimp pond bottom sludge greatly increases the management cost, and reduces the economic and ecological benefits of farming to a certain extent. In addition, the water exchange method of large-scale drainage and large-scale irrigation has led to secondary pollution of the water quality of surrounding sea areas and other shrimp ponds by nutrients and organic pollutants in the water, resulting in eutrophication and frequent disease occurrence in local sea...
