In the last 30 years, the global aquaculture industry has developed rapidly, the fastest growth in animal food production, and China's contribution to the production of aquaculture products is the largest. According to the data of "Aquaculture Industry Market Outlook and Investment Strategy Planning Analysis Report" released by Prospect Industry Research Institute, in recent years, China's aquaculture production accounted for about 2/3 of the world's aquaculture production, of which, the total production of freshwater aquaculture for many years has been ranked the world's first in recent years at an annual rate of about 22%, accounting for 42% of the country's total aquaculture production; seawater aquaculture has a longer history
Marine aquaculture has a long history, marine aquatic products accounted for about 57.72% of the total aquatic production.
From the point of view of the absolute amount, in 2004, China's aquatic products production was 42.47 million tons; in 2015, the total national aquatic products production of 66.9965 million tons, an increase of 3.69% over 2014.
In high-density aquaculture operations, the incidence of fish diseases and pests tends to be higher, and the harvested fish often have a large amount of pesticides and other chemical residues left in their bodies, and the water quality will deteriorate as a result. In future aquaculture, it is inevitable that natural farming will be carried out in a low-density aquaculture environment to avoid the use of pesticides and pollution as much as possible.
Today, the gradual development of aquaculture, multi-species regional aquaculture will gradually favor a single species of specialties, a single species of aquaculture is more conducive to the formation of strong varieties, to strengthen the regional uniqueness of the aquaculture industry, widen the gap with the surrounding aquaculture industry, and in the fierce competition of the aquaculture industry to increase their own farming advantages and competitiveness.
