Description

Technical Field

[0001] This utility model relates to the field of aquaculture equipment technology, and in particular to an aquaculture system for fish fry breeding. Background Technology

[0002] Fish fry breeding can improve the spawning rate, fertilization rate, and hatching rate, facilitating planned production. Through breeding, fry with poor body shape and weak constitution can be eliminated, and superior individuals can be selected to improve existing varieties or create new varieties.

[0003] To improve the hatching rate of fish fry, traditional aquaculture methods involve setting up nursery grids, small cells made of cement bricks, with one female and one male fish placed in each grid. After the female fish lays fertilized eggs, workers need to collect the fertilized eggs from each grid. Due to the small size and large number of grids, the collection efficiency is low, time-consuming, and labor-intensive. Furthermore, because the grids are fixed and cannot be moved, cleaning the nursery grids is inconvenient after the fish fry have hatched. Therefore, there is an urgent need to design an aquaculture system that facilitates fish fry breeding. Utility Model Content

[0004] The purpose of this invention is to provide a breeding system for fish fry propagation, which can solve the problems of inconvenient collection of fertilized eggs during the fish fry propagation process and inconvenient cleaning of the seedling trays after the fish fry propagation is completed.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A fish fry breeding system includes a pond containing multiple fry cells; a support frame is installed above the pond, and multiple lifting devices are installed on the support frame for hoisting the fry cells, each lifting device corresponding to one fry cell; the lifting devices lift the fry cells, and workers enter the pond to collect and clean the fish eggs.

[0007] Preferably, the seedling grid is composed of multiple small grids; each small grid has a through hole at the bottom of its four sides for connecting the various small grids with the water inside the pool.

[0008] Preferably, a drainage ditch is provided on one side of the pool.

[0009] Preferably, the top of the seedling tray is provided with four lugs, and each lug is connected to a chain of the same length; the bottom of the lifting device is provided with a hook for suspending the chain, and the hook is on the same vertical line as the center of gravity of the seedling tray.

[0010] Preferably, the lifting device is one of a pneumatic cylinder, a hydraulic cylinder, or an electric crane.

[0011] Preferably, the seedling tray is made of stainless steel.

[0012] Preferably, a shade net is placed on top of each seedling grid, and the area of ​​each shade net is larger than that of the seedling grid.

[0013] Preferably, the shade net is woven from iron wire or PP material.

[0014] This invention uses a lifting device to suspend the seedling trays above the water surface, allowing workers to collect all the fish eggs in the pool and clean both the pool and the seedling trays. Because the seedling trays are suspended above the water, workers are not obstructed when collecting the fish eggs, and it is also easier to clean the pool and seedling trays separately, making cleaning more convenient and reducing blind spots.

[0023] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand the advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] Example 1

[0025] This invention uses a lifting device 4 to suspend the seedling tray 3 above the water surface, allowing workers to collect all the fish eggs in the pool 1 and clean both the pool 1 and the seedling tray 3. Because the seedling tray 3 is suspended above the water surface, workers are not obstructed when collecting the fish eggs, and it also facilitates separate cleaning of the pool 1 and the seedling tray 3, making cleaning more convenient and reducing blind spots.

[0026] like Figure 1-2 As shown, a fish fry breeding system includes a pond 1 containing multiple fry cells 3; a support frame 2 is installed above the pond 1, and multiple lifting devices 4 for hoisting the fry cells 3 are installed on the support frame 2, with each lifting device 4 corresponding to one fry cell 3; the lifting devices 4 lift the fry cells 3, and workers enter the pond 1 to collect and clean the fish eggs.

[0027] Furthermore, the seedling tray 3 is composed of multiple small trays 301; such as Figure 3 As shown, each small grid 301 has a through hole 302 at its bottom, which is used to connect the small grids 301 with the water inside the pool 1.

[0028] like Figure 4 As shown, a drainage ditch 101 is further provided on one side of the pool 1. The drainage ditch 101 is used to drain the aquaculture wastewater before cleaning the pool 1 and the seedling grid 3. At the same time, fish eggs can also be screened and collected by arranging a screen at the location of the drainage ditch 101.

[0029] Furthermore, the top of the seedling grid 3 is provided with four support ears 303, and each support ear 303 is connected to a chain 304 of the same length; the bottom of the lifting device 4 is provided with a hook 401 for suspending the chain 304, and the hook 401 is on the same vertical line as the center of gravity of the seedling grid 3, so as to ensure that the seedling grid 3 is stable as a whole during the hoisting process.

[0030] Furthermore, the lifting device 4 is one of a pneumatic cylinder, a hydraulic cylinder, or an electric crane.

[0031] Furthermore, the seedling tray 3 is made of stainless steel. Stainless steel is not easily rusted, will not affect the breeding environment, and is easy to clean.

[0032] like Figure 4-5 As shown, further, a shade net 5 is placed on top of each seedling grid 3, and the area of ​​each shade net 5 is larger than that of the seedling grid 3 so that it can completely cover the seedling grid 3.

[0033] Furthermore, the shade net 5 is woven from iron wire, polyester fiber, or PP material. The function of the shade net 5 is to reduce light penetration into the seedling tray 3. The length and width dimensions of the shade net 5 can be customized according to specific needs.

[0034] Shade nets are categorized into five models based on the number of threads per 25 millimeters of warp and weft: 8-thread, 10-thread, 12-thread, 14-thread, and 16-thread. The higher the stitch count, the denser the mesh, resulting in better shading and a higher density. Common stitch counts include 2, 3, 4, 6, 8, and 12 stitches, corresponding to shading rates ranging from 40% to 95%.

[0035] Shade nets are commonly available in colors such as black, green, and silver-gray, with different colors suitable for different scenarios and needs. When choosing a shade net, you can select the appropriate material, size, stitch count, and color based on the specific usage scenario and requirements.

[0036] Working principle:

[0037] When fish eggs need to be collected, the shade net 5 is manually removed, then the chain 304 is connected to the hook 401, and the lifting device 4 is activated. The lifting device 4 smoothly raises the seedling grid 3 to a certain height, allowing the staff to fully enter the water tank 1. The staff uses a sieve to scoop and collect the fish eggs in the water tank 1. After the fish eggs have been collected, the drainage ditch 101 is opened. Before opening, a sieve is placed in the drainage ditch 101 to further collect the fish eggs. After the water in the water tank 1 is drained, the water tank 1 and the seedling grid 3 are cleaned.

[0038] The sieves used for catching fish eggs come in the following sizes: First filter sieve: 35 mesh, 35cm inner diameter, with a first limiting protrusion 1 on the outer bottom. Second filter sieve: 45 mesh, 35cm inner diameter, with a second limiting protrusion 1 on the outer bottom. Third filter sieve: 70 mesh, 35cm inner diameter, with a third limiting protrusion 1 on the outer bottom. These sieves can be used in combination to filter fish eggs according to their size.

[0039] When breeding the next batch of fish fry, the lifting device 4 is activated to lower the frying grid 3 into the water tank 1, with the water bodies interconnected through the through-holes 302. Workers place one male and one female fish in each small grid 301 for mating. A shade net 5 is placed over the frying grid 3 depending on the weather conditions.
