Description

Fish culture device

Technical Field

The invention belongs to a pond fish culture device.

Background

The existing pond fish culture all utilizes the traditional natural water culture method, namely, the water in the pond is basically not changed from the time of putting the fry to the time of fishing, and the situation of realizing the water replacement of the pond by utilizing natural flowing water is also facilitated. In any mode, as the fish is fed at fixed points and eaten intensively, and the fish is discharged in water, a large amount of microorganisms and germs in the pond water are propagated, the water quality is deteriorated, the longer the retention time of the pond water is, the more polluted the pond water is, more and more toxic and harmful substances and fish dung are in the pond, the probability that the fish body is infected by the toxic and harmful substances in the pond is increased, and the probability that the bottom of the pond is anoxic is also increased. In severe cases, hypoxia will cause death of the fish. The fish body meat quality and taste of the traditional culture method are poor, and concentrated eating causes uneven feeding, some can not eat, and causes different fish body sizes. Therefore, the fishpond is cleaned once a year, and old water is pumped, discharged and new water is injected. When the fishpond is cleaned, old pond water is firstly pumped to be dry, toxic and harmful sludge in the pond is removed, and then new water is injected to carry out the next feeding. Time, labor and energy consumption.
