Description

Technical Field

[0001] This utility model relates to the field of fish farming technology, and in particular to a fixing device for blood collection from silver pomfret. Background Technology

[0002] Silver pomfret is one of my country's four major marine economic animals and an important economic fish in many countries, with huge market demand. However, due to overfishing, wild resources are severely threatened. In the early 21st century, Ningbo University, the East China Sea Fisheries Research Institute, and other institutions pioneered work on its nutrition, immunization, reproduction, and aquaculture techniques. In 2015-2016, the Ningbo University silver pomfret team successfully overcame the challenges of large-scale silver pomfret farming and seedling cultivation, greatly advancing the industrialization of silver pomfret. With the breakthrough in seedling cultivation, more biological questions about silver pomfret have attracted the attention of many scientists. For example, frequent diseases during the hot summer months greatly affect industrial promotion, making disease immunization crucial, and blood collection is a key step in this process.

[0003] In the artificial breeding of silver pomfret, to avoid disease infestation, it is necessary to test the farmed fish for bacteria and parasites. This is done by puncturing the caudal artery of the silver pomfret to collect blood, and then analyzing the blood to determine the health status of the silver pomfret. However, silver pomfret "die immediately after being taken out of the water," the reason being their susceptibility to stress. Preliminary experiments revealed that the conventional method requires one person to hold the fish down with one hand and collect blood with the other. This is not only inconvenient for single-handed operation, requiring a second person to assist, but also causes the silver pomfret to struggle and jump intermittently, causing the needle to become blocked or displaced, hindering the blood collection process. Furthermore, the silver pomfret dies within minutes of being taken out of the water, greatly increasing the difficulty of blood collection. Scales rubbed off the silver pomfret's body and water droplets adhering to it also easily contaminate the fixing device, making cleaning difficult. Therefore, there is an urgent need to design a fixing device suitable for blood collection from silver pomfret to achieve rapid and efficient blood collection. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a fixing device for blood collection from silver pomfret to shorten the blood collection time, extend the survival time of silver pomfret during blood collection, and significantly improve the blood collection efficiency of silver pomfret.
