Description

Technical Field

[0001] This utility model relates to the field of crayfish breeding and farming technology, and in particular to a crayfish breeding and farming pond. Background Art

[0002] Crayfish are widely popular for their high nutritional value and delicious taste, making them an important freshwater shrimp species in my country. Crayfish are relatively small, with adults weighing around 30 to 50 grams. They live in shallow water and prefer to burrow during the breeding season. Their burrows are located about 20 centimeters above the water surface and contain a small amount of water to maintain humidity. The burrow entrance is usually sealed with a mud cap to reduce water loss. Crayfish larvae can be raised using a rice-crayfish co-culture method. After planting rice, the surrounding ditches are drained and cleared of debris, forcing the crayfish to burrow and reproduce. After the rice harvest, the pond is left to dry for 7 to 10 days before being flooded to submerge the crayfish in their burrows. However, this method has several drawbacks: the floodwaters may cause the burrows to collapse and kill the crayfish inside, or the burrow entrance may be blocked, preventing the crayfish from escaping. Furthermore, the drying process may cause the water temperature inside the burrows to rise, leading to crayfish mortality. Utility Model Content

[0026] Example 1

[0027] See attached document Figure 1-7This application provides a crayfish breeding pond, including a concrete paddy field embankment 1 with a heat insulation layer and a rice planting area 2. The heat insulation layer can prevent the concrete paddy field embankment 1 from getting too hot and affecting the growth of crayfish. A ditch 3 is provided between the concrete paddy field embankment 1 and the rice planting area 2. The ditch 3 is used for raising crayfish. The ditch 3 is provided with a water inlet 28. The water inlet 28 is equipped with a filter screen. The water inlet 28 is connected to a water pump through a water pipe 8, which can supply water to the ditch 3 and drain water. Water is supplied through the concrete paddy field ridges 1, which include horizontal ridges 4, vertical ridges 5, and a central ridge 6. The horizontal ridges 4 and vertical ridges 5 are connected end-to-end to form a U-shape surrounding the rice planting area 2. The central ridge 6 is located between two rice planting areas 2. The water pipes 8 are connected to a water tank via a water pump, which pumps water from the tank into and out of the water pipes 8. The holes 7 are arranged in rows horizontally on the horizontal ridges 4, vertical ridges 5, and central ridge 6. The bottom of each hole 7... The system has several through holes 27, and each row of holes 7 is connected to a water pipe 8 through the through holes 27. Each hole 7 is filled with soil, which is used for crayfish to burrow and reproduce. The working principle is as follows: In rice-crayfish co-culture, after rice is planted, water is pumped from the ditch 3 through the water inlet 28 to remove debris, forcing the crayfish to burrow and reproduce. Tea cake is used to clean the ditch 3. After the rice is harvested, water is passed through the water pipe 8, submerging or flushing the crayfish out of their holes into the ditch 3. This application utilizes the concrete... The earthen embankment 1 is equipped with the aforementioned caves 7, which are filled with soil to meet the needs of crayfish for burrowing and reproduction. At the same time, the caves 7 are not easy to collapse. After the crayfish larvae have hatched for a period of time, the water pipe 8 is used to flush or force the crayfish out of the caves 7. The concrete embankment 1 avoids the hidden danger of the crayfish being crushed by the collapse of the caves 7 after being flooded. Water is supplied from behind the caves 7 through the water pipe 8 to ensure that the crayfish in each cave 7 are flushed out, thereby improving the survival rate of the crayfish. The structure is simple.

[0028] Specifically, the concrete embankment 1 is equipped with a humidity detection device 9, which extends longitudinally through the cave 7. The humidity detection device 9 includes a first base 10, a first upper cover 11, and a hygrometer 12. The hygrometer 12 is connected to the first upper cover 11, and the first base 10 is connected to the concrete embankment 1. The first base 10 and the first upper cover 11 are threaded together. The first base 10 has an internal thread, and the first upper cover 11 has an external thread that mates with the internal thread. The hygrometer 12 can be installed or removed by rotating the first upper cover 11. Crayfish prefer shade, and by monitoring the humidity inside the cave 7 with the humidity detection device 9, it can be determined whether the water pipe 8 needs to supply water to the cave 7. The structure is simple and convenient to use and maintain.

[0029] Specifically, the concrete field ridge 1 is equipped with a temperature detection device 13, which extends longitudinally through the cave 7. The temperature detection device 13 includes a second base 14, a second upper cover 15, and a thermometer 16. The thermometer 16 is connected to the second upper cover 15, and the second base 14 is connected to the concrete field ridge 1. The second base 14 and the second upper cover 15 are threaded together. The second base 14 has an internal thread, and the second upper cover 15 has an external thread that mates with the internal thread. The hygrometer 12 can be installed or removed by rotating the second upper cover 15. The temperature detection device 13 monitors the internal temperature of the cave 7. If the internal temperature of the cave 7 is too high, the water in the water pipe 8 is pumped out by a water pump, and at the same time, cooler water is injected into the water pipe 8 by a water pump, thereby switching the water body to cool down the cave and maintain a suitable internal temperature. The structure is simple and convenient to use and maintain.

[0030] Specifically, a net 17 is provided around the outer perimeter of the concrete field embankment 1. The net 17 is at least 1.5 meters high and extends at least 30 centimeters into the bottom of the pond to prevent crayfish from escaping.

[0031] Example 2

[0032] See attached document Figure 1-7 The difference between this embodiment and Embodiment 1 is that the rice planting area 2 is surrounded by a perimeter stake 18 and a partition 19. The perimeter stake 18 is provided with a slot 20, and the partition 19 is inserted into the slot 20. The rice planting area 2 is isolated by the partition 19 inserted into the perimeter stake 18, which facilitates the pumping and cleaning of the ditch 3, forces crayfish to burrow and reproduce, and also ensures the stability of the water volume in the rice planting area 2 when water needs to be added to the ditch 3. The structure is simple.

[0033] Specifically, a partition 21 is provided outside the rice planting area 2, and the bottom of the partition 19 is inserted into the partition 21. The partition 21 plays a sealing and isolation role, preventing water from seeping between the rice planting area 2 and the ditch 3 from the bottom of the partition 19, and ensuring that the water level of the rice planting area 2 and the ditch 3 is at the required position. The structure is simple.

[0034] Specifically, the partition 21 is provided with a mud-proof plate 22, and the mud-proof plate 22 is provided with a cylindrical foot 24 fixedly connected to one end of a spring 23. The partition 21 is provided with a circular hole 25, and the other end of the spring 23 is fixedly connected to the bottom of the circular hole 25. The mud-proof plate 22 is installed in the partition 21. When there is no additional external force, the spring force of the spring 23 will lift the partition 21 out of the partition 21 opening. When the partition 19 is installed, the mud-proof plate 22 is compressed into the partition 21 under the weight of the partition 19. At this time, the spring 23 is pressed down, realizing the installation of the partition 19. When the partition 19 is removed, the mud-proof plate 22 rebounds and resets under the spring force of the spring 23, preventing mud and sand from entering the partition 21 and causing blockage, which would prevent the partition 19 from being inserted. The structure is simple.

[0035] Specifically, the concrete field embankment 1 is equipped with a drainage outlet 26, which is used to discharge excess water when the water level is too high, to prevent crayfish from escaping when the water level is too high, and to maintain the water level in the ditch 3. The structure is simple.

[0036] Specifically, the horizontal ridge 4, the vertical ridge 5, and the middle ridge 6 are all equipped with slopes, which facilitate crayfish climbing up to dig burrows and reproduce. The structure is simple and reasonable.

[0037] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
