[0002] The large yellow croaker belongs to Perciformes, Sciaenidae and Pseudosciaena, and is a special local marine fish in China. The large yellow croaker is the fish with the highest single yield and the largest culture scale in marine net cage culture in China, and is one of the eight most advantageous export aquatic products in China with an annual output value of more than 10 billion yuan. Due to overfishing, the wild large yellow croaker population cannot form a fishing season, the number decreases sharply, and the germplasm resource declines. Collecting and keeping alive the wild large yellow croaker is an important preliminary work for large yellow croaker original strain selection. Ensuring the keep-alive rate of the large yellow croaker can effectively carry out the work of large yellow croaker original strain selection. Since the wild large yellow croaker mainly lives in the water layer with a depth of 10 meters, sudden capture to the water surface will cause the swim bladder to expand and die due to pressure change. At the same time, the scales of the large yellow croaker are easy to fall off, which can be easily lost during the keep-alive process. The wild large yellow croaker is a broad-spectrum carnivorous fish and is afraid of strong light, which is not easy to domesticate and feed in a cement pool. Therefore, a transportation device is needed for transporting and transferring the large yellow croaker after being captured.
