Clean pond cage culture system

Abstract

A clean pond cage culture system mainly comprises a cage (1) and is characterized by further comprising a settling box (2). The settling box (2) comprises a water pusher (3), blades (7) and a blowdown box (5). When an inner bottom aerating plate of the water pusher (3) operates, waterflow formed in aerating scours dirt settling at the bottom of the settling box (2) under guidance of the inclined blades (7), and the dirt in the settling box (2) moves along the settling box (2) towards the blowdown box (5) and enters the blowdown box (5). The dirt in the blowdown box (5) can be discharged by starting a blowdown pump. The clean pond cage culture system integrates cage culture, aeration, dirt collection, dirt settling and blowdown, maintains water cleanliness for pond cage culture, and is worthy of popularization and application.

Description

technical field [0001] The invention relates to a pond culture technology, in particular to a pond net cage cleaning culture system. technical background [0002] At present, the pond fish farming method is to raise fish loosely in the whole pond, and all the excrement and residual bait of the fish settle at the bottom of the pond, forming harmful silt, reducing the effect of pond cultivation and the service life of the pond. Pond cage culture is mainly a frame structure, which is made of steel, bamboo poles, etc. to make a rectangular frame, and the upper, lower and four sides are surrounded by nets. The disadvantage of this kind of cage is that the metabolites and residual bait in the cage are directly discharged into the pond and settle in the bottom mud of the pond, which does not change the accumulation of harmful substances in the pond, but also destroys the water quality in the cage and limits the output of the cage. [0003] Compared with traditional pond culture, p...
