Perch cannot be cultured with sea salt. The artificial breeding technology of sea bass is not yet mature, so it is not suitable for artificial breeding. Bass is a marine fish. It is ferocious in nature and feeds on fish and shrimp. The main producing areas are Qingdao, Shidao, Qinhuangdao and Zhoushan Islands in China. The fishing season is spring and autumn, with October to November being the peak fishing season.

Sea bass, also known as flower bass, seven-star bass, etc. Mainly distributed in the shallow coastal waters of China, North Korea and Japan. It is distributed along the coast of China and likes to inhabit estuaries, and can also be traced upstream to freshwater areas of rivers. China's Zhoushan Islands in the East China Sea and the Jiaodong Peninsula in the Yellow Sea produce more fish, and it is one of the economic fish. At present, artificial breeding of many marine fish cannot be fully realized. I believe that with the development of science and technology, it will be realized in the near future.
