Description

Technical Field

[0001] The utility model belongs to the technical field of California sea bass seedling marking, and specifically relates to a net cage for indoor California sea bass seedling marking. Background Art

[0002] The largemouth black bass belongs to the order Perciformes, the suborder Perciformes, the family Acanthidae, the genus Melanogaster, and is also known as the California bass. The largemouth black bass has delicious taste, tender meat, high protein content, and rich nutrition. It is deeply loved by consumers and has huge market potential. It has become an important farmed fish in my country with huge economic value. In the breeding process of largemouth black bass, the cultivation of fry is a vital link. Poor cultivation of fry often leads to a lack of fish in the entire breeding market. The cultivation of largemouth black bass fry includes three processes: the cultivation of water splash fry, the opening of water splash fry, and the marking of fry. Among them, the marking stage is very critical. If the marking is not done well, the fry will not quickly switch from eating Artemia to eating artificial compound feed, which will directly lead to the inability to carry out subsequent fry cultivation.

[0003] At present, the cultivation of largemouth black bass fry is mainly completed by placing the fry in indoor cement pools. During the largemouth black bass training process, the fry need to be concentrated and domesticated as much as possible, so that they can switch from eating Artemia to eating artificial compound feed, and the fry need to be screened by size during the training process. Therefore, it is hoped that the fry can be concentrated for easy operation. If the fry are too scattered and cannot be converted to food in a short period of time, it will often lead to the death of a large number of fry, which directly leads to the failure of fry cultivation or a small number of fry cultivated.

[0004] In summary, the utility model provides a net cage for indoor standard seedlings of California bass to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model aims to provide a net cage for indoor standard fry of California bass, which has the advantages that the fry can be lured to a designated area by an attracting lamp arranged in the middle of one side of the upper net basket, and the fry can be concentrated in the net basket through the net basket composed of two rectangular frames, four columns and a mesh surface, so that it is convenient for staff to concentrate on domesticating the fry from eating Artemia to eating artificial compound feed, effectively preventing the large-scale death of the fry due to the dispersion of the fry and the inability to convert the fry into food in a short time, and effectively improving the survival rate of the fry. At the same time, the rectangular frame and the column wall made of PVC pipe are relatively thin, which makes it convenient for the net basket to float on the pool and prevent the fry from escaping from the top of the net basket.
