Description

Technical Field

[0001] The invention belongs to the technical field of fishery breeding equipment, and in particular relates to a breeding device and method for feeding floating feed at fixed points. Background Art

[0002] In aquaculture, traditional feeding methods often have problems such as uneven feed distribution and difficulty in accurately controlling the feeding position, which lead to adverse consequences such as feed waste, water pollution, and uneven fish growth. Fixed-point feeding can overcome the above-mentioned defects. First of all, fixed-point feeding is to accurately place feed in areas where aquatic animals gather and are convenient for feeding, so as to avoid waste caused by feed being dispersed in the water body, ensure that the feed can be effectively utilized, and meet the nutritional needs of aquatic animals at specific growth stages. Secondly, fixed-point feeding can effectively reduce feed loss, and the complex water environment. Factors such as water flow, water temperature, and water quality will affect the distribution and state of feed. In addition, by concentrating the feed in a specific location, the scouring and diffusion effects of factors such as water flow on the feed can be reduced, and the suspension and loss of feed in the water can be reduced, thereby improving feed utilization and reducing breeding costs.

[0003] In the prior art, when too much feed is put in or the distribution is unreasonable, the uneaten feed will rot and decompose in the water, releasing a large amount of organic matter and nutrients, such as nitrogen and phosphorus. These substances will promote the excessive reproduction of algae and bacteria in the water, consume the dissolved oxygen in the water, and cause the water quality to deteriorate. Fixed-point feeding can accurately control the amount and range of feed put in, reduce the amount of uneaten feed from the source, and reduce the degree of water pollution. In the area of ​​fixed-point feeding, the remaining feed is relatively concentrated, which is convenient for the breeders to find and clean it in time. At the same time, by setting up water quality monitoring equipment at the feeding point, the water quality changes in the area can be more accurately understood, and corresponding water quality adjustment measures such as water change, oxygenation, and adding water quality improvers can be taken in time to maintain a good water quality environment and provide suitable living conditions for aquatic animals. Therefore, there is an urgent need to develop a breeding device that can feed fish feed at a fixed point. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the main purpose of the present invention is to provide a breeding device for feeding floating feed at a fixed point, which can accurately control the feeding position, realize fixed-point feeding of floating feed, improve feed utilization, reduce water pollution, and promote the healthy growth of fish.

[0005] Another object of the present invention is to provide a method for feeding floating feed at a fixed point, which is achieved by the above-mentioned breeding device for feeding floating feed at a fixed point.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] A first aspect of the present invention provides a fixed-point feeding aquaculture device for feeding floating feed, comprising a fixed-point feeding device assembled by a floating ring, a seine, and a plurality of rolling belts; wherein:

[0008] The floating ring is evenly distributed and fixed to the outside of the enclosure through a plurality of tie bands, and is used for fixed-point feeding of floating feed;

[0009] The length of the floating ring, the length of the enclosure and the number of the tie ties are calculated based on the area of ​​the breeding pond and then fixedly assembled.

[0010] Preferably, the height of the fence is 40 cm and the aperture is 1 mm.

[0011] Preferably, the floating ring, the seine and the rolling belt are all made of polyethylene.

[0012] Preferably, the size of the floating ring is determined according to the feeding area of ​​the automatic feeding machine, or occupies 5%-10% of the area of ​​the breeding pond.

[0013] Preferably, the floating ring is circular in shape to achieve fixed-point feeding at different positions.

[0014] The second aspect of the present invention provides a method for feeding floating feed at a fixed point, comprising: determining a fixed-point feeding position in an aquaculture pond, distributing the fixed-point feeding device therein, and feeding the floating feed into the floating circle of the fixed-point feeding device at a regular time and in a fixed quantity, thereby completing the fixed-point feeding.

[0015] Preferably, the fixed-point feeding position is located in a breeding pond with a moderate water depth, near the water inlet, in a sheltered place and close to the oxygenation equipment.

[0016] Preferably, the timed and quantitative feeding is feeding the fish at a fixed time every day according to a daily feeding amount of 5% of the fish body weight.

[0017] It's important to note that the fixed-point feeding floating feed aquaculture device must be securely installed to prevent it from drifting in the wind. The floating feed is then regularly and quantitatively placed into the floating ring of the fixed-point feeding device. During use, the mesh may become fragile due to long-term weathering; therefore, it should be promptly inspected and replaced. The floating ring may sink due to water ingress due to inadequate connection; therefore, it should be connected to ensure its stability. Cable ties may break due to long-term weathering; therefore, they should be promptly inspected and replaced.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] ① The floating feed feeding device of the present invention allows for fixed-point feeding, allowing users to clearly monitor how much food the fish have consumed, thus avoiding feed waste due to overfeeding. It also prevents excess feed from decomposing in the water and affecting water quality. For example, goldfish have no sense of fullness and are prone to overeating. Fixed-point, fixed-quantity feeding can effectively prevent this problem.

[0020] ② The fixed-point floating feed feeding device of the present invention facilitates observation of the fish's condition. Feeding at a fixed location allows for clearer observation of each fish's feeding behavior, appetite, swimming posture, etc. If a fish exhibits a loss of appetite, sluggish movements, or is driven away by other fish and unable to eat normally, these conditions can be detected in a timely manner. These may be signs of illness or attack by other fish, allowing for early action.

[0021] ③ The present invention's fixed-point floating feed feeding system maintains clean water quality. This system concentrates feed in a single area, reducing the chance of feed being dispersed and deposited in corners of the fish tank. Uneaten feed can be easily removed from the designated location, reducing the organic matter content in the water and the risk of water quality deterioration, creating a favorable living environment for the fish.

[0022] ④ The aquaculture device for feeding floating feed at fixed points in the present invention can cultivate the conditioned reflex of fish. With long-term fixed-point feeding, the fish will get used to waiting for food at a specific location. When they see someone approaching the feeding point or a feeding signal appears, they will actively gather around, increasing the interactivity and fun of fish farming.

[0027] In order to more fully understand and demonstrate the technical solutions, objectives, and advantages of the present invention, the following is a further detailed and complete description of the technical effects produced by the present invention in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. It should be pointed out that for those skilled in the art, other embodiments obtained without departing from the concept of the present invention are all within the scope of protection of the present invention.

[0028] like Figure 1 As shown, the following embodiment exemplarily describes a fixed-point feeding aquaculture device for feeding floating feed, including a floating ring, a fence, and a plurality of rolled straps fixedly assembled to form a fixed-point feeding device. The floating ring 2 is evenly distributed and fixed to the outside of the fence 1 by a plurality of tie straps 3 for fixed-point feeding of floating feed. The length of the floating ring 2, the length of the fence 1, and the number of tie straps 3 are calculated based on the area of ​​the aquaculture pond and then fixedly assembled.

[0029] In some embodiments, the height of the fence 1 is 40 cm and the aperture is 1 mm.

[0030] In some embodiments, the materials of the floating ring 2, the seine 1 and the rolling belt 3 are all polyethylene.

[0031] In some embodiments, the size of the floating ring 2 is determined according to the feeding area of ​​the automatic feeding machine, or occupies 5%-10% of the area of ​​the breeding pond.

[0032] In some embodiments, the shape of the float ring 2 is circular, so as to achieve fixed-point feeding at different positions.

[0033] A method for fixed-point feeding of floating feed comprises: determining a fixed-point feeding position of an aquaculture pond, distributing fixed-point feeding devices therein, and feeding floating feed into a floating circle of the fixed-point feeding device at a fixed time and in a fixed quantity to complete the fixed-point feeding.

[0034] In some embodiments, the fixed feeding location is located in a breeding pond at a moderate water depth, near the water inlet, in a sheltered place, and close to an aeration device.

[0035] Example 1

[0036] 1. Test site

[0037] This experiment was conducted in the breeding grounds of Shenhang Ecological Technology Development Co., Ltd. in Suzhou, Jiangsu Province. Two ponds with the same breeding area and breeding weight of 500kg grass carp were installed. Figure 1Observations show that in ponds with and without fixed-point feeding devices, fish can be clearly observed gathering within the device's perimeter to feed. In ponds without fixed-point feeding devices, however, the fish's feeding location shifts with the direction of the feed's float. Small amounts of feed drift downwind, impacting shore and preventing the fish from feeding, causing water pollution.

[0038] 2. Collection of leftover bait

[0039] Two experimental ponds were fed the same weight of floating grass carp feed daily, with the daily feed amount being 5% of the fish's body weight. The remaining feed was collected daily after the fish stopped feeding. After 30 days of the experiment, the total amount of remaining feed in the ponds was weighed. The results showed that the ponds equipped with fixed-point feeding stations had approximately 14 kg of remaining feed, while the ponds without fixed-point feeding stations had approximately 27 kg of remaining feed, roughly double the amount in the ponds equipped with fixed-point feeding stations. This demonstrates that the present invention's floating feed farming device can significantly reduce the amount of floating feed fed, thereby lowering farming costs.

[0040] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
