Abstract

A water floating feed loss prevention device for an aquaculture pond comprises a pond (1), a drainage pipe (2) is additionally arranged in the pond (1), and the water floating feed loss prevention device is characterized in that a plurality of feed fences (3) are additionally arranged in the pond (1), each feed fence (3) is composed of four stand columns (4) fixed to the bottom of the pond, a feed fence (5) is arranged at the upper ends of the stand columns (4) in a surrounding mode, the upper end of each feed fence (5) is higher than the water surface, and the lower end of each feed fence (5) sinks into water. Fish enters the feed fence from the stand columns and takes feed underwater, and the feed in the feed fence cannot flow out of the feed fence to flow into the drainage pipe (2) along with water flow due to blocking of the upper end of the feed fence. The water floating feed can be prevented from being lost, feeding of fishes is not affected, and meanwhile the fishes fed with the water floating feed can be prevented from being hurt by the fishes and birds fed with the water floating feed.

Description

Technical Field

[0001] This utility model relates to an aquaculture technology, and more particularly to an aquaculture device, specifically a device for preventing the loss of floating feed in aquaculture ponds. Background Technology

[0002] Currently, floating feed is commonly used in fish farming. This feed floats on the water surface, making it easy for fish to eat. However, this feed is also easily moved by water currents or wind, especially towards drain outlets, where it enters the drainage system, causing significant waste, particularly during water changes or sewage discharge. To address this, Chinese Patent 2022228613853 discloses a feed loss prevention structure for aquaculture cages, Chinese Patent 2020222531297 discloses a feed loss prevention ring for marine aquaculture cages, and Chinese Patent 2016201483615 discloses a fish breeding cage for preventing waterfowl jumping and feed loss. These devices have solved the feed loss problem to some extent, but they cannot solve the problems existing in surface aquaculture. These issues must be addressed. Utility Model Content

[0003] The purpose of this invention is to address the problem of floating feed easily being lost through drainage outlets in existing aquaculture, resulting in feed waste. This invention designs a device to prevent the loss of floating feed in aquaculture ponds.

[0004] The technical solution of this utility model is:

[0005] A device for preventing the loss of floating feed in aquaculture ponds includes a pond 1 and a drainage pipe 2 installed in the pond 1. The device is characterized by having multiple feed enclosures 3 installed in the pond 1. Each feed enclosure 3 consists of four pillars 4 fixed to the bottom of the pond. A feed net 5 is installed at the upper end of the pillars 4. The upper end of the feed net 5 is above the water surface, and the lower end is submerged in the water. Fish enter the feed enclosure between the pillars and take feed from underwater. Due to the obstruction at the upper end of the feed net, the feed in the feed net will not flow out of the feed net and into the drainage pipe 2 with the water flow.

[0006] The upper end of the feed enclosure 5 is 5-10 cm above the water surface, and the lower end is 10-20 cm below the water surface.

[0007] The column 4 is made of wood or galvanized steel pipe.

[0008] The aperture of the feed enclosure 5 should be smaller than the particle size of the feed pellets.

[0009] The beneficial effects of this utility model are:

[0010] This invention can prevent the loss of floating feed without affecting the fish's feeding, and at the same time prevent fish-eating birds from harming the fish.

[0011] The posts of this invention not only serve as anchors for the enclosure net, but also reduce water ripples caused by wind, prevent surface disturbances, and minimize stress on the fish.

[0012] This utility model has a simple structure, is easy to manufacture and install, and is simple and easy to operate. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 As shown.

[0016] A device for preventing the loss of floating feed in aquaculture ponds includes a pond 1, with a drain pipe 2 installed in the pond 1. The height of the drain pipe 2 is adjustable, and the adjustment method is the same as in existing technologies. Multiple feed enclosures 3 are installed in the pond 1, the number of which can be designed and determined according to the stocking density and water surface area. Each feed enclosure consists of four pillars 4 fixed to the bottom of the pond (which can be made of wood or galvanized pipe, driven into the pond bottom soil, or fixed with cement blocks). A feed net 5 is installed at the upper end of the pillars 4. The aperture of the feed net 5 should be smaller than the particle size of the feed. The upper end of the feed net 5 is 5-10 cm above the water surface, and the lower end is submerged 10-20 cm in the water. Fish can enter the feed enclosure between the pillars and ingest feed underwater. Due to the feed covering, the fish generally do not surface while feeding, thus protecting them from predatory birds. The feed within the net is prevented from flowing out and into the drain pipe 2 by the water flow.

[0017] The structures, proportions, and sizes illustrated in the accompanying drawings are solely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this specification are merely for clarity and not intended to limit the scope of implementation. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention's implementation.

[0018] The above embodiments are merely preferred embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and equivalent substitutions can be made without departing from the principle of this utility model. All such technical solutions after improvements and equivalent substitutions to the claims of this utility model fall within the protection scope of this utility model.

[0019] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
