A high-efficiency ecological breeding equipment for circulating freshwater fishery

Abstract

The invention discloses a high-efficiency ecological breeding equipment for circulating freshwater fishery, which includes a pond bank and a pond. A water changing device for draining and replenishing the pond is arranged inside the pond, and guide rails are fixedly connected between the symmetrical side walls of the two ponds. , the guide rail is slidably connected with a moving plate, and the moving plate is welded with a support plate and a hinge seat, and the hinge seat is rotatably connected with a wire wheel, and the support plate is connected with a feed feeding device for feeding the pond. The water device includes a water outlet pipe and a water inlet pipe. One end of the water outlet pipe passes through the bottom of one side of the pond and is connected to a water pump at the other end of the pool bank. The part outside the bank of the pool is connected to a water pump. The invention has the advantages of setting a water changing device to replace the water with lower oxygen content in the lower layer of the pond, improving the dissolved oxygen condition of the water near the bottom layer, increasing the stocking amount and output, and feeding the fish living in the lower layer of the water body through the feeding device.

Description

technical field [0001] The invention relates to the technical field of high-efficiency breeding of freshwater fishery, in particular to high-efficiency ecological breeding equipment of circulating freshwater fishery. Background technique [0002] The technical and management work of using ponds for fish farming and breeding is pond aquaculture. Pond aquaculture is the main aquaculture method in China. In recent years, with the increasing demand for pond aquaculture, pond facility aquaculture has become a new direction of development. At present, domestic Pond facility technology mainly focuses on water intake and drainage facilities, construction of dining tables, and optimization of slope protection. [0003] In order to make reasonable use of bait and water, bring into play the mutually beneficial effect between fish, promote double harvest of adult fish species, and improve social and economic benefits, pond fish farming is suitable for polyculture mode, that is, polycult...
