Present situation and development prospect of aquaculture

The development prospect and present situation of aquaculture are as follows:

1, analysis of aquaculture status

Aquaculture plays an important role in the fishery industry structure of China and plays an important role in promoting the development of chinese fisheries economics. In order to accelerate the development of aquaculture, the state and relevant departments have successively issued relevant policies to provide a good development environment for aquaculture.

According to the report "World Fisheries and Aquaculture in 2022", the total output of fisheries and aquaculture will rise to the highest level in history in 2020, reaching 2140,000 tons, including 6,543.8 million tons of aquatic animals and 36 million tons of algae.

China's fishery is developing well, the output of aquatic products is increasing steadily, the supply and demand of aquatic products are booming, the prices are rising and falling, the import and export trade volume of aquatic products is increasing, and the income of fishermen is increasing rapidly.

In terms of aquaculture area, in 202 1 year, the national aquaculture area was 7009.38 thousand hectares, down by 0.38% year-on-year. Among them, the mariculture area was 2025.55438+0 thousand hectares, up by1.50% year-on-year; The freshwater aquaculture area was 4,983.87 thousand hectares, a year-on-year decrease of1.12%; The area ratio of mariculture to freshwater culture is 28.9: 7 1. 1.

With the continuous improvement of China's environmental awareness in recent years, many parts of the country have carried out actions to protect the ecological environment and rectify aquaculture pollution. A large number of aquaculture cages in inland areas have been dismantled, shrimp ponds and fish ponds have been backfilled and closed, many beaches in coastal areas have also been designated as no-breeding areas, and many oyster rows and piles have also been dismantled, resulting in a continuous decline in China's aquaculture area.

2. Analysis on the development prospect of aquaculture.

At present, the consumption of aquatic products in the domestic market is mainly fresh aquatic products. However, with the acceleration of social life, the repeated impact of COVID-19 epidemic, the change of residents' consumption habits, and the demand for time-saving, healthy and cost-effective diet.

Chain catering enterprises have a high demand for standardized production, cost reduction and efficiency improvement, which makes convenient and fast prefabricated foods, including frozen and refrigerated prefabricated aquatic products, sought after by catering enterprises and individuals, and the demand is increasing.

With the development of science and technology, intelligent aquaculture provides a development direction for aquaculture. In the future development, remote sensing images, artificial intelligence technology, geographic information system and other technologies will be used to further determine the details of biological growth in aquaculture, so as to make regulatory decisions according to actual production and gradually solve objective problems caused by different aquaculture environments.

In 20021year, the Ministry of Agriculture and Rural Affairs formulated and issued the "Fourteenth Five-Year Plan for National Fisheries Development", which put forward specific requirements and plans for aquaculture in the future. By 2025, the quality, efficiency and competitiveness of fisheries will be significantly enhanced, the supply capacity of aquatic products will be steadily improved, the industrial structure will be more reasonable, and the green development of aquaculture will achieve positive results.

Significance of developing aquaculture

1, which can provide high-quality animal protein food for human beings economically. In animal breeding, fish is a kind of aquatic animal with variable temperature, which consumes less energy than domestic animals and poultry with constant temperature on land, has high feed conversion efficiency and high animal protein content in products.

2. It can provide raw materials for industry and is an important source of raw materials for pharmaceutical industry, chemical industry and feed industry.

3. It plays an important role in making up for the shortage of marine fishing. With the rapid growth of world population and economic development, the demand for animal protein is increasing, but the catch is limited by the renewal of natural fishery resources. Fishery forecast points out that the trend of increasing annual catch has reached its peak, and it will not be able to meet the demand only by fishing natural fishery resources in the future.

4. Conducive to maintaining ecological balance. In offshore areas, due to the increase of aquaculture output, the fishing intensity can be reduced and the ecological imbalance caused by overfishing can be prevented; In inland waters, the combination of aquaculture and other agricultural production is conducive to the formation of a benign ecological cycle.
