AI Technical Summary
The existing laboratory containers cannot effectively simulate the natural shelling environment of river crabs, resulting in river crabs being unable to dehull normally in the laboratory, increasing the risk of death and possibly misleading the experimental results.
A container for raising river crabs in laboratory was designed, including an open rectangular container shell and an auxiliary shelling device. The auxiliary shelling device consists of partitions, columns and load-bearing plates to simulate the fixed environment of river crabs when they are unshelled in the wild, and protects the newly unshelled river crabs from impacts from other river crabs.
Through auxiliary shelling devices that simulate the natural environment, the unexpected death of river crabs caused by difficulty in shelling in the laboratory is reduced, the survival rate of river crabs is improved and the reliability of experimental results is enhanced.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of experimental equipment, in particular to a container for culturing river crabs in a laboratory. Background Art
[0002] In some experimental studies, river crabs are used as experimental animals. In order to ensure the activity of the experimental animals, river crabs are raised in suitable containers according to the specific needs of the experiment.
[0003] In existing experiments, the containers used to culture river crabs are mostly ordinary containers for other purposes, rather than special containers, which cannot specifically complete the task of raising river crabs in the laboratory. In particular, when facing the physiological molting development of river crabs, there is no suitable device to simulate the natural environment to assist molting, resulting in unexpected deaths in the laboratory due to the inability of river crabs to molt normally, thus misleading the experimental results. Utility Model Content
[0004] In order to solve the problem described in the above background technology that there is no suitable device to simulate the natural environment for assistance, resulting in unexpected deaths of river crabs in the laboratory due to the inability of river crabs to molt normally, the utility model provides a container for culturing river crabs in the laboratory.
[0005] The technical solution adopted by the utility model is:
[0006] A container for culturing river crabs in a laboratory comprises a container shell and an auxiliary shelling device, wherein the container shell is an open rectangular container; the auxiliary shelling device consists of a partition, a column and a load-bearing plate.
[0007] The columns are erected in the container shell, the lower edges of the columns touch the bottom surface of the container shell, the load-bearing plates are placed flat on the columns, and the partitions are placed flat on the plane of the load-bearing plates.
[0008] Preferably, the side of the load-bearing plate that is not in contact with the side wall of the container shell has a vertically upward edge.
[0009] Preferably, the top end of the column passes through the load-bearing plate and is embedded in the partition.
[0010] A set of auxiliary shelling devices is respectively arranged on both sides of the bottom of the container shell.
[0011] Preferably, a set of the auxiliary shelling device includes a partition, a load-bearing plate and six columns.
[0012] More preferably, the six columns are arranged in three rows and two columns.
[0013] The utility model provides a container for culturing river crabs in a laboratory, which has the following beneficial effects: using an auxiliary shelling device and a height-reducing partition to assist river crabs in shelling and protect the newly shelled river crabs, so as to reduce the unexpected death phenomenon caused by the shelling of river crabs in collective cultivation of a certain number of crabs.

[0020] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.
[0021] like Figure 1-5 As shown, the embodiment of the utility model relates to a container for laboratory breeding of river crabs, comprising a container shell 1 and an auxiliary shelling device. The container shell 1 is an open rectangular container with a length of 500 mm, a width of 400 mm, and a height of 200 mm.
[0022] A set of auxiliary shelling devices is provided on both sides of the bottom of the container shell 1. A set of auxiliary shelling devices consists of a partition 2, a load-bearing plate 4 and six columns 3. The six columns 3 are arranged in three rows and two columns. The columns 3 stand in the container shell 1, the lower edge of the columns 3 touches the bottom surface of the container shell 1, the load-bearing plate 4 is placed flat on the columns 3, the partition 2 is placed flat on the plane of the load-bearing plate 4, and the top of the column 3 penetrates the load-bearing plate 4 and is embedded in the partition 2. The side of the load-bearing plate 4 that does not contact the side wall of the container shell 1 has a vertical upward edge, and the width of the load-bearing plate 4 is slightly larger than the width of the partition 2, just so that the partition 2 is placed flat in the plane of the load-bearing plate 4.
[0023] The width of the partition 2 is 150mm, the length is 400mm, the thickness is 2mm, and the vertical distance from the partition 2 to the bottom of the container shell 1 is 20mm; the spacing between the six columns 3 is 50mm, the row spacing is 100mm, and the diameter of the column 3 is 2mm; the load-bearing plate 4 is 5mm thick, 400mm long, slightly wider than the width of the partition 2, and the edge height is 10mm.
[0024] The utility model provides a container for culturing river crabs in the laboratory, which is used for culturing Chinese mitten crabs. The applicable culturing range is 5g to 20g, and the maximum number of Chinese mitten crabs that can be culturated is 30. Under field conditions, Chinese mitten crabs need to fix their bodies with attachments such as water plants during the molting period before starting to molt, thereby breaking the new shell out of the old shell. Under conventional laboratory container culturing conditions, there are no attachments for the Chinese mitten crabs to fix, which will make it difficult for the Chinese mitten crabs to molt and reduce their survival. The auxiliary shelling device simulates the wild environment to provide the Chinese mitten crabs with attachments of appropriate thickness to achieve the effect of assisting the Chinese mitten crabs in molting. At the same time, it simulates the cave environment for only a single river crab to pass through, which can protect the crabs that have just completed molting from being harmed by the impact of other river crabs.
