Description

Technical Field

[0001] This utility model relates to the technical field of aquaculture feeding devices, and in particular to a floating platform for feeding fish fry in net cages. Background Technology

[0002] Cage aquaculture has been rapidly promoted in some parts of my country due to its simple structure, low investment, and convenient management. It is a new aquaculture method for the development of intensive production in the aquaculture industry. Depending on the species stocked, it is divided into feeding cages and non-feeding cages. Moreover, as the aquaculture industry develops towards large-scale, intensive, and professional development, the requirements for aquatic feed are also increasing. Extruded feed is widely accepted and increasingly valued in aquaculture because of its good stability in water, which can reduce the dissolution and loss of nutrients in the feed and reduce the pollution of water bodies. The usage of extruded feed is constantly increasing.

[0003] However, extruded feed, due to its buoyancy, easily floats out of the feeding box during feeding competition among fish, resulting in feed waste. In aquaculture, extruded feed is often fed by placing bottomless feeding nets made of polyethylene mesh, triangular or quadrilateral enclosures made of bamboo, or quadrilateral or circular enclosures made of foam strips in the pond to intercept the feed. However, these three types of feeding platforms are not effective in intercepting feed during feeding competition among larger fish, especially in windy conditions. Furthermore, if the floating extruded feed is not consumed by the fish in time, it will stick to the walls of the feeding platform as the fish compete for it, resulting in waste. If uneaten feed accumulates over time, it is prone to mold and odor, affecting the aquaculture environment and hindering the healthy growth of the fish, thus reducing aquaculture efficiency. Utility Model Content

[0004] In view of the above-mentioned technical problems, this utility model provides a floating platform for feeding fish fry in net cages, which reduces the problems of feed waste and decreased breeding efficiency in net cage aquaculture.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A floating platform for feeding fish fry in a net cage is characterized by comprising a feeding platform, a gravity block, a fixing structure, and reinforcing ropes. The feeding platform is fixed with reinforcing ropes on its upper and lower sides, the feeding platform is fixed with a gravity block on its lower side, and the feeding platform is surrounded by a fixing structure.

[0007] The feeding platform is composed of multiple mesh panels sewn together.

[0008] The mesh is a polyethylene mesh.

[0009] The fixing structure includes a connecting buckle, an upper suspension rope, a lower suspension rope, and an upper suspension hook. Each corner of the top of the feed platform is connected to one end of the upper suspension rope through a connecting buckle, and each corner of the bottom of the feed platform is connected to one end of the lower suspension rope through a connecting buckle. An upper suspension hook is provided on the lower suspension rope.

[0010] Each corner of the feed platform is equipped with a support rod, and the upper and lower ends of the support rod are provided with fixing holes. Connecting buckles are fixed at the fixing holes, and the connecting buckles fix the support column and the feed platform together.

[0011] The gravity block has a threaded hole on its upper side, and the support rod has a threaded structure on its lower side. The support rod is fixed to the gravity block through the threaded structure.

[0012] The feeding platform is installed inside the fixed aquaculture cage.

[0013] The other end of the suspension rope is connected to the frame that secures the aquaculture cage.

[0014] The other end of the suspension rope is connected to the frame of the fixed aquaculture cage.

[0015] The cages are for aquaculture.

[0016] The fixing rope is made by folding the top and bottom edges of the feed platform's mesh to a width of about 1 cm and then sewing the fixing rope inside, making the feed platform, which is made of sewn mesh, sturdy and durable.

[0017] The polyethylene mesh is the main body of the feeding platform, and it is rectangular in shape. Its length and width are randomly determined according to the specifications of the aquaculture cage, and its height is determined according to the number and size of the fish being raised.

[0018] The top of the feed platform is the feeding port.

[0019] The beneficial effects of this utility model are:

[0020] In this invention, a feeding platform made of multiple polyethylene mesh panels is installed inside the aquaculture cage. This feeding platform is stably positioned in the center of the cage, serving as the key location for feeding. At the time of feeding, the feed falls onto the central area above the feeding platform. The length, width, height, and mesh size of the polyethylene mesh panels can be flexibly adjusted according to the specific dimensions of the aquaculture cage, the size of the fish fry, and the size of the feed particles, ensuring that feed does not leak out and minimizing waste.

[0021] To prevent the extruded feed on the feeding platform from floating off the platform or even escaping from the aquaculture cages due to wind or competition for food by fish, this invention cleverly installs gravity blocks at the four corners of the bottom edge of the feeding platform. These gravity blocks firmly anchor the feeding platform, ensuring its stability and reliability.

[0022] In addition, the utility model discloses especially installed the upper suspension hook in the middle section position of the lower suspension rope. When not needing to feed, the lower suspension rope can pull up the feed table from the water surface, and the hook stably fixes the feed table in the air. This design not only facilitates the cleaning and disinfection of the feed table, but also can keep the freshness of the feed during the airing process. The specific position of the hook is determined according to the fixed frame height of the breeding net cage and the feed table water depth.

[0023] In order to enhance the pulling force of the feed table and prolong its service life, the top edge and the bottom edge of the polyethylene mesh are folded about 1cm wide, and the fixing rope is skillfully wrapped therein. Such design not only improves the durability of the feed table, but also provides solid support for it.

[0024] The utility model not only improves the breeding efficiency, but also greatly optimizes the use efficiency of the feed, and brings significant convenience and benefit for the aquaculture industry. BRIEF DESCRIPTION OF DRAWINGS
