With the transformation of China's economic development, the adjustment of agricultural structure has also entered a critical period, and the structural reform of the supply side of aquaculture is also deepening. "Qualification and reduction" has become the main topic of transition agriculture. The impact of structural reform on the supply side on aquaculture, the development trend of aquaculture in China and the trend of industry change are obvious, mainly reflected in the following two aspects:

(1) Ecological farming

Today, when the country strongly advocates "ecological environmental protection", how to solve environmental problems has become a hot issue in the society. Actively promoting water-based culture in the development of aquaculture is one of the important measures to protect the ecological environment and promote the good development of the aquaculture industry.

Aquaculture is the use of simulated ecosystems and natural ecosystems to develop aquatic products in a healthy and ecological way (such as clear water for fish farming, food for fish farming, and grass farming for fish) to satisfy people's pursuit of green food. The psychological needs of "earth" goods, so as to achieve a true unity of economic, social and ecological benefits. With the government's vigorous promotion of energy conservation and environmental protection, through the construction of a healthy aquaculture management system for aquatic products, the active construction of a sustainable breeding mechanism, and the active research on water-producing aquaculture technology, etc., we will further promote the development of water-based aquaculture and provide health for consumers. High quality aquatic products may become one of the trends in aquaculture.

(2) "Internet + Aquaculture"

In recent years, the development of "Internet +" technology has penetrated into all aspects of aquaculture, from breeding, production, process management and services to final product sales. The integration of “Internet +” with aquaculture has greatly improved the efficiency and level of aquaculture. With the application and promotion of more and more "Internet +" technology in the aquaculture industry, the intelligent breeding system based on Internet of Things, automation control and artificial intelligence technology realizes real-time online monitoring and precise regulation of the breeding process, using "Internet + "Combined with market sales (selling online fish), it has greatly improved the informationization, automation and intelligence level of the farm, reduced production costs for factory and large-scale farming, and improved labor productivity, market sales rate and resource utilization. Rate and management efficiency, but also won the advantage of the quality and safety of aquatic products and market competitiveness.

Then the question is coming. What kind of fish does the "newcomer" raise? What is the difficulty of breeding special fish?

In recent years, many newcomers have been involved in the aquaculture industry, but they are still in a certain "unfamiliar" state of farming technology. In addition, the development of the famous special aquatic products culture is also relatively rapid, with a wide variety and innovation. Some people rely on people's eagerness to seek for a rich heart, whether to change the face of the same variety to take the name, or to use the varieties that are not suitable for certain conditions to use the people to seek "new, strange, special" mentality to promote sales. Some farmers have embarked on the road to get rich, but there are also many farmers who have failed in farming due to farming techniques and misunderstanding of the market or variety, which is embarrassing!

For novice fish farming, what kind of fish is good? What is the difficulty of breeding special fish? It can be decided by combining the following points with the actual situation of the company.

(1) Consider the feasibility of feeding technology.

The biological characteristics of the famous special aquatic products are often quite different from those of the general cultured fish. In particular, some species have strict requirements on the breeding conditions, such as: meaty bait and self-inflicted meat of carnivorous fish. Problems, the wintering problem of tropical fish, etc., when considering raising it, it is necessary to fully prepare and accurately judge the feeding technology, feeding (bait) materials, funds, technology, conditions, etc., and make a detailed plan. .

(2) Consider the possibility of feed supply.

Many special aquatic products require animal feed or high-protein bait, such as California salmon, black mullet, etc.; some even need fresh active animal (meat live bait) feed, such as squid, bullfrog. The breeding of these varieties must take into account the source and supply of animal feed. Of course, the cost of the feed must also be considered, and the bait channel should be widely opened. Such as fishing snails, scorpions, sputum; use of livestock and poultry waste; can also use polyculture to reduce the use of feed, such as the use of fish and shrimp polyculture, fish and crab polyculture and other modes. In short, it is necessary to adjust the production according to local conditions and when the feed source is insufficient.

(3) Consider the stability of the seedling source.

The cultivation of special aquatic products generally has higher seed costs. Therefore, it is necessary to select breeding species that can be self-bred and self-bred, or varieties that can stably obtain seedlings in nearby seedling fields and natural waters.

(4) Make full use of local regionality.

For special aquaculture, it is necessary to pay attention to the use of local farming conditions and regional advantages, to foster strengths and avoid weaknesses, and not to chase the well-bred breeds with good market conditions. Focus on brand advantages, we must carefully analyze the market needs and capacity, predict development trends and feasibility.

(5) To avoid the singularity of the breed.

At present, many special aquatic products are cultured, and the technology has not yet completely passed through, and some are in the experimental stage. Therefore, if a single species is completely raised, once the breeding fails or the product is not sold, the economic loss will not be remedied. To this end, it is best for farmers to implement integrated operations, three-dimensional farming, and polyculture of fish to minimize risk losses.

(6) Consider the extensiveness of sales channels.

Special aquatic products have high cost of cultivation and low volume, so the price is also high, but it also limits many consumers. If mass production is to be carried out, sales channels should be widely opened. Some varieties can be combined with local sales and foreign sales, and combined with mainland sales and export sales, such as river crabs and green shrimps.
