Description

Technical Field

[0001] The utility model belongs to the field of fine-mesh cages for three-dimensionally culturing shrimps and crabs in rice fields, and particularly relates to a fine-mesh cage for three-dimensionally culturing shrimps and crabs in rice fields. Background Art

[0002] Three-dimensional breeding of shrimps and crabs in rice fields is a breeding method that combines shrimps and crabs with rice fields. This breeding model is to release shrimps and crabs in rice fields, and use the water and straw in the rice fields to provide a living environment and food for shrimps and crabs. At the same time, shrimps and crabs in rice fields can also provide organic fertilizers for rice fields and promote the growth of rice. The main feature of three-dimensional breeding of shrimps and crabs in rice fields is that it makes full use of the space and resources of rice fields and realizes the mutual beneficial symbiosis between shrimps and crabs and rice fields. Under this breeding method, shrimps and crabs can grow freely, and by eating pests such as weeds and insects in rice fields, they play a certain role in prevention and control. At the same time, the water in the rice fields can also provide sufficient water and nutrients, providing good conditions for the growth of shrimps and crabs. The fine mesh cage for three-dimensional breeding of shrimps and crabs in rice fields is a tool used in the breeding process. It is usually a mesh structure made of plastic or metal materials with tiny holes that can prevent shrimps and crabs from escaping and allow water to pass freely. The main function of the fine mesh cage is to confine shrimps and crabs to a specific area to prevent them from wandering or escaping in the rice fields. This helps to manage and control the number of shrimps and crabs, and is convenient for observing and collecting breeding conditions. At the same time, the fine-mesh cage can also provide certain protection to prevent intrusion by external predators. The design and material selection of the fine-mesh cage need to take into account the size and characteristics of the shrimps and crabs to ensure that they can effectively restrict the activities of the shrimps and crabs and keep the water flow unobstructed. In addition, the cleaning and maintenance of the fine-mesh cage are also matters that need to be paid attention to during the breeding process to maintain the health and growth of the shrimps and crabs. In the prior art, when the device is in use, the device does not have a limiting mechanism, and the device as a whole is not convenient to be limited, which may cause the device as a whole to move, and when the shrimps and crabs in the device need to be taken out, the device does not have a pulling mechanism, and the shrimps and crabs in the device are not convenient to be taken out, resulting in the device being inconvenient to use.
