Description

Technical Field

[0001] The utility model relates to the technical field of rice crab breeding, in particular to a wintering storage pond for Chinese mitten crabs. Background Art

[0002] Rice-crab farming is based on the theory of rice-crab farming, crab-rice farming, and rice-crab symbiosis. In the rice-crab farming environment, crabs can clear weeds in the fields, eat pests, and their excrement can fertilize the fields and promote rice growth. Rice in turn provides rich natural bait and good habitats for the growth of river crabs, which is mutually beneficial and forms a virtuous ecological cycle. One of the main species in rice-crab farming is the Chinese mitten crab (river crab), which has a life cycle of 1 to 3 years. In winter, river crabs need to enter the bottom of the pond or hide in caves to overwinter. Affected by low temperatures, their foraging and activity will be greatly reduced. Therefore, in order to ensure the safe overwintering of river crabs, it is necessary to use overwintering storage ponds to increase the survival rate of river crabs overwintering.

[0003] After searching, it is found that a blue crab wintering pond is disclosed in a utility model patent with Chinese patent publication number CN214801725U. The blue crab wintering pond in the utility model patent is provided with an air filling pipe and a heating rod in the pond, and the temperature can be adjusted according to actual conditions to ensure sufficient dissolved oxygen in the water body. However, on the one hand, the wintering pond is only a high-density gathering place for crabs to temporarily inhabit in winter. The blue crab wintering pond is provided with a heating rod to maintain a relatively high water temperature, which will lead to an increase in the activity of the crabs, which not only requires supplementary food consumption, but also increases the casualties caused by a large number of crabs fighting in the wintering pond with high density crab storage. On the other hand, the blue crab wintering pond adopts a conventional water injection method to maintain the required dissolved oxygen concentration, which is easy to cause the pond water to surge, and the crab activity stirs the pond bottom, causing harmful substances on the pond bottom to float up and cause harm to the crabs. Therefore, the blue crab wintering pond needs to be further improved in terms of storage structure, so a Chinese mitten crab wintering storage pond is proposed. Utility Model Content
