Description

[0001] The present invention relates to a batch pond aquaculture system and method,

The present invention relates to a sequential batch pond culture system and method.

Pond culture is not only a major form of Chinese aquaculture but also a major source of aquatic products. In 2015, the total area of freshwater ponds in the whole country is 2701,000 hectares, and its production amount reaches 21,956,900 tons. This is 32.8% of the total fishery production in the country, and it is acting as a substitute for food safety. China has a long history of pond cultivation and is the country that has developed pond culture in the earliest years in the world. Healthy aquaculture technologies such as "mulberry-based fisheries", "sugar cane-based fisheries" and "eight-way farming" in China have made a huge contribution to the world aquaculture industry. It is now faced with problems such as degradation of the aquaculture environment, degradation of facilities, serious collapsing area, serious dirt, excessive water resources waste, inefficient farming methods and eco economic benefits, which are serious obstacles to the continuous development of pond aquaculture In the past, for a long time, people did not give importance to pond cultivation because of the universality and coherence of inland pond cultivation, and as a result, It is said that 3 ~ 13.4 m ³ is needed to obtain 1 kg of fish through pond culture. Each year N, P dose of is about 1550 kg / hm ² and 580 kg / hm ^2, which TSS, COD _Mn, TN, direct discharge of TP is about ^{2280 kg / hm 2, 200 kg} / hm 2, 100 kg per year / hm ² and 5.0 kg / hm ^2. Since the mid-90s of the 20th century, pond farming has been continuing, and people have begun to study the issues of environmental restoration of the seawater pond, The ecological process technology of the aquaculture has gradually started to develop as well. Currently, domestic and overseas softwood cultivars are rapidly developing, and there are many types of closed pond culture system, multiple pond circulation system, These include pond farm ecological systems, pond ecological fairing circulation aquaculture systems, separate pond aquaculture systems, and runway pond aquaculture systems. These various forms of form have certain effects There are still a number of problems, however, when viewed as a whole.

The first is that traditional pond cultivation methods are one side of the pond, which makes it difficult to control the water environment, which causes problems such as deterioration of the aquaculture environment, soil volume, and production rate.

Second, pond mixing mode and wagon wheel - shaped farming method have the problem of high impact on emergency situation of fish in high density culture situation, though they are improving ecological efficiency, have high culture risk and low aquaculture effect.
