Tidal change based automatic fish feeding net cage device and using method thereof

Abstract

The invention belongs to the technical field of marine fishery, and particularly relates to a tidal change based automatic fish feeding net cage device. The tidal change based automatic fish feeding net cage device comprises two supports, wherein a net cage, a discharging box and a feeding box are fixedly connected between the two supports; the discharging box communicates with the net cage through a discharging pipe; the discharging box communicates with the feeding box through a first pipeline, wherein one support is fixedly connected with a material storage box; the material storage box communicates with the feeding box through a second pipeline; a floating plate is connected between the two supports in a sliding mode; the discharging pipe penetrates through the floating plate; and a push plate is connected into the feeding box in a sliding mode. The floating plate can be driven to float upwards through rising of seawater during tide rising, a closing mechanism is automatically opened in cooperation with the pushing force of the pushing plate, automatic feeding of fish schools is achieved, tedious manual tide change monitoring is avoided, and meanwhile the labor loss of manual feeding is reduced.

Description

technical field [0001] The invention belongs to the technical field of marine fishery, and in particular relates to a net cage device for automatically feeding fish based on tidal changes and an application method thereof. Background technique [0002] Since the reform and opening up, my country's aquaculture industry has developed rapidly, the scale of aquaculture has continued to expand, the number of breeds has increased, and the output has increased rapidly. In order to expand the scale of aquaculture and reduce the area used on land, sea cage culture is becoming more and more common. Sea cage culture It has the advantages of superior water quality, good quality fish products, vast sea area, resource saving, flexible maneuvering, convenient management, less investment and high efficiency. [0003] When raising sea cages, in order to make the fish eat better, they often choose to put bait on the fish when the tide is high, because when the tide is high, due to the influx o...

Problems solved by technology

[0003] When raising sea cages, in order to make the fish eat better, they often choose to put bait on the fish when the tide is high, because when the tide is high, due to the influx of external sea water, the water level of the breeding point rises to realize the exchange of water flow. Make the water body very clear and the water quality is good, which will directly cause the fish school to have a big appetite and be able to eat, and the visibility in the water is high, so the fish school can clearly see the bait they are feeding in the water, so they become extremely active , the enthusiasm for grabbing food has also increased. After strenuous exercise, the feed they eat is naturally easily digested and absorbed, which is conducive to the growth of fish schools and greatly improves the economic benefits of fish farming. Bring the sand, pollutants, and silt from the shore into the sea together. At this time, the seawater is much turbid than at high tide, which is not conducive to fish eating. In order to ensure the timing of feeding fish, it is often necessary to manually observe tide changes, and then Adding bait to the cages one by one is cumbersome and wastes manpower
