Description

Floating feed salvaging and sterilizing device in aquaculture pond

Technical Field

The invention relates to the technical field of aquaculture, in particular to a floating feed salvaging and sterilizing device in an aquaculture pond.

Background

Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under artificial control. Generally comprises the whole process of cultivating aquatic products from seedlings under artificial feeding management. In a broad sense, this may also include the proliferation of aquatic resources.

Aquaculture has modes of rough culture, intensive culture, high-density intensive culture and the like. The rough culture is to put seedlings in medium and small natural waters and to culture aquatic products such as fish in lakes and reservoirs, shellfish in shallow seas and the like by completely relying on natural baits. Intensive culture is to culture aquatic products such as pond fish culture, net cage fish culture, fence culture and the like in a small water body by using bait casting and fertilizing methods. The high-density intensive culture adopts methods of flowing water, controlling temperature, increasing oxygen, feeding high-quality baits and the like to carry out high-density culture in a small water body so as to obtain high yield, such as flowing water high-density fish culture, shrimp culture and the like.

Aquaculture is higher relatively to the requirement of quality of water, need regularly carry out disinfection treatment to the water source in the aquaculture pond, what adopt among the prior art is that the manual work is disinfected to the water surface of aquaculture pond mode of spraying the antiseptic solution to the quality of water in the aquaculture pond, such mode is consuming time power not only, it spouts the mixture and sprays inhomogeneously still to appear the antiseptic solution easily, cause the poor problem of disinfection effect, and cause the pollution sources of pollution numerous to quality of water in the aquaculture pond, wherein float nature fodder that fish did not eat up when involving aquaculture floats on the water surface, will cause the pollution to aquaculture's quality of water in the past for a long time, so design one kind and carry out the device of salvaging and the device of disinfecting to the water source in the aquaculture pond to the float nature fodder on the water surface of aquaculture pond and be indispensable.

Disclosure of Invention

Aiming at the technical defects in the prior art, the invention aims to provide a device for salvaging and disinfecting floating feed in an aquaculture pond, which is used for solving the problems that the floating feed which is not eaten by fishes in the aquaculture pond pollutes the water quality of the aquaculture pond for a long time and the water source in the aquaculture pond is disinfected by manually spraying disinfectant, so that the disinfectant is easily mixed and unevenly sprayed, and the disinfection effect is poor.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
