Problems solved by technology
During the experiment, it may be necessary to periodically take blood, inject drugs, and gavage the live fish. Because the live fish is easy to jump and smooth, it is difficult to fix, which brings troubles to the fish experiment.
At present, the most common way to solve this problem is to anesthetize the fish before the experiment, but this method has the following disadvantages: (1) It is difficult to define the type, dosage, and action time of the anesthetic, and if it is used improperly, it is easy to cause the fish to die ; (2) Since the anesthetic will affect the fish body, the accuracy of the experimental results will be reduced; (3) The operation is complicated, pollutes the environment, and the cost is high

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can understand the present invention.
[0018] An experimental fish fixing device. The fixing device includes a rectangular fixing plate 5. On the fixing plate 5, there are two inner and outer layers of protrusions forming a closed loop. The two layers of protrusions are both cylindrical. The fixing device also includes a fixing The fixed net passes through the two layers of protrusions on the fixed plate and is movably connected to the fixed plate 5. The area of the fixed plate 5 is larger than that of the fixed net. There are a pair of holes 6 at both ends of the fixed plate 5, and hooks are arranged on the four corners of the fixed net. 7. The hook 7 is movably connected to the hole 6, and the fixed net can firmly fix the entire fish body without causing injury or death.

The invention relates to a fish fixing device, in particular to the fish fixing device for an experiment. The fish fixing device for the experiment is characterized by comprising a fixing plate, wherein an inner layer of protrusions and an outer layer of protrusions which form a closed loop are arranged on the fixing plate, the fixing device further comprises a fixing net, and the fixing net penetrates through the protrusions on the fixing plate and is movably connected with the fixing plate. The fish fixing device has the advantages that the damage to a fish body caused by anesthetic is avoided, accuracy of the experimental result is improved, and the device is low in cost, simple in structure and high in practicability.
Description
Technical field [0001] The invention relates to a fish fixing device, in particular to an experimental fish fixing device. Background technique [0002] Fish is one of the main groups of aquatic organisms, and it has always been an important species related to the development of fisheries. In order to understand fish more clearly and more deeply, and to explore the relationship between itself and nature, researchers have done a lot of experiments on various fishes. During the experiment, it may be necessary to periodically take blood, inject drugs, and gavage the live fish. Because the live fish is easy to beat and smooth, it is difficult to fix, which brings trouble to the fish experiment. At present, the most commonly used method to solve this problem is to anesthetize the fish before the experiment, but this method has the following shortcomings: (1) The type, dosage, and action time of the anesthetic are difficult to define. If used improperly, it is easy to cause the fish t...
