Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains. The terms “first,” “second,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Similarly, the terms “an” or “a” and similar terms do not indicate a limitation of quantity, but rather indicate the presence of at least one.

[0029] refer to Figure 1 and Figure 2 This embodiment provides a crayfish temporary holding system, including a water purification tank 10, a crayfish temporary holding tank 20, a wastewater treatment unit 30, and a spare crayfish temporary holding tank 40.

[0030] The water purification pond 10 provides clean water to the crayfish temporary holding pond 20. The water purification pond is an ordinary water pond. By planting water-purifying plants, such as bitter gourd, in the pond, the ordinary water is treated by the water-purifying plants to obtain clean water. The clean water is transported to the crayfish temporary holding pond 20 through a pipeline. Preferably, a water pump is installed on the pipeline.

[0031] The crayfish holding pond 20 discharges wastewater automatically through an overflow mechanism. The wastewater is connected to the wastewater treatment unit 30 via a pipe. The wastewater treatment unit 30 treats the wastewater discharged from the crayfish holding pond 20, including biological methods such as using plants to absorb and utilize the nutrients of the crayfish in the wastewater.

[0032] The spare pool 40 for crayfish temporary holding ponds is used as a spare pool when cleaning the crayfish temporary holding pond 20. It has the same structure as the crayfish temporary holding pond 20 and is located adjacent to it. It is connected to the water purification pond 10 and the wastewater treatment unit 30 through pipes.

[0033] The crayfish holding pond 20 is mainly used to clean and remove mud from the crayfish, thereby improving their quality and increasing their selling price. Specifically, the crayfish holding pond 20 includes a pond body 21, a water distribution pipe 22, an escape-prevention baffle 23, a river sand layer 24, an aeration head 25, and a drainage pipe 26.

[0034] The pool body 21 is constructed of cement, including the bottom, surrounding side walls and openings. The cement construction increases the sturdiness and durability of the pool body and makes it easy to clean.

[0035] The water distribution pipe 22 is installed around the opening at the upper end of the pool body 21. Multiple water outlets are formed around the opening of the water distribution pipe, preferably with the outlets facing the bottom of the pool body 21. The water purification tank 10 is connected to the water distribution pipe 22. Preferably, a water pump is installed between the water purification tank 10 and the water distribution pipe 22 to spray clean water from the water purification tank 10 into the pool body 21 through the outlets. The water sprayed from the outlets exerts a certain rinsing force on the crayfish in the water. Preferably, the water distribution pipe 22 comprises multiple pipes, which are laid side-by-side at the opening of the pool body 21, allowing for faster water injection and a larger and more uniform rinsing area for the crayfish in the pool.

[0036] The escape-prevention baffle 23 is installed around the opening at the upper end of the pool body 21 and below the water distribution pipe 22 to prevent crayfish from climbing out of the pool body 21. The specific structure and materials of the escape-prevention baffle 23 can refer to existing technology.

[0037] The river sand layer 24 is laid at the bottom of the pool body 21. Preferably, the thickness of the river sand layer 24 is 5cm. When the crayfish move in the river sand layer 24, the river sand layer 24 effectively removes mud and debris from the crayfish's surface by rubbing against it. The river sand layer 24 has gaps inside, which can settle the mud and debris on the crayfish's body and the excrement they excrete, so that the water in the crayfish holding pool can be kept relatively clean.

[0038] The aeration head 25 is installed above the river sand layer 24. The aeration head 25 oxygenates the water and washes the gills of the crayfish, causing the mud in the gills to fall off. Preferably, the aeration head 25 is a disc-shaped aeration head; there are multiple aeration heads 25, which are evenly distributed within the pool body 21.

[0039] One end of the drain pipe 26 is connected to the bottom of the pool body 21 for automatic overflow. Combined with the continuous water injection from the water purification pool, this ensures the water in the crayfish holding tank is flowing, maximizing the crayfish survival rate. Specifically, the other end of the drain pipe 26 is lower than the opening of the pool body 21, allowing the water level in the crayfish holding tank to automatically overflow when it reaches a certain point. Preferably, a crayfish escape prevention device and a sand-prevention device are installed at the connection point between the drain pipe 26 and the pool body 21.

[0040] The method for constructing the crayfish temporary holding pond includes:

[0041] 1. Select a suitable location to construct the water tank body 21, and reserve a drainage hole at the bottom of the cement tank body 21.

[0042] 2. Install the drain pipe and the aeration head 25 at the bottom of the water tank body 21, and lay a layer of river sand at the bottom of the cement tank body 21 to form the river sand layer 24;

[0043] 3. Install the escape prevention baffle 23 and the water distribution pipe 22 at the corresponding positions of the opening of the water tank body 21.

[0044] The method of using the crayfish holding pond includes:

[0045] 1. Close the outlet of the drain pipe 26 and connect the water distribution pipe 22 to the water purification tank 10 via a pump;

[0046] 2. Turn on the pump to fill the crayfish holding tank with water to the required level;

[0047] 3. Open the outlet of the drain pipe 26 and connect the drain pipe 26 to the wastewater treatment unit;

[0048] 4. Start the operation of the aeration head 25;

[0049] 5. Add the crayfish.

[0050] The crayfish holding ponds are used to clean and remove mud from the crayfish. After 1 to 2 days, clean crayfish can be obtained, which improves the quality of the crayfish, increases the selling price, and increases commercial revenue.

[0051] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the scope of protection of the present invention. The scope of protection of the present invention is determined by the appended claims.
