What is the development and trend of aquaculture, what problems are faced and how to solve them?
Aquaculture is an important part of China's national economy. As a pillar industry of aquaculture, mariculture has made important contributions to the construction of national economy and the improvement of people's living standards. However, with the rapid development of mariculture, problems such as seawater pollution, aging shrimp ponds, black and smelly sediment deposition, and large-scale catastrophic virus disease outbreak and epidemic have been exposed rapidly, which makes people question the traditional predatory culture mode. Bioremediation technology is the latest environmental engineering technology developed at home and abroad in recent 10 years. It has been successfully applied to soil, urban rivers and lakes, groundwater, offshore pollution control, agriculture, animal husbandry, aquaculture and other fields, and has become one of the fastest-growing high-tech fields of environmental science and technology in the 20th century. Different from the traditional predatory aquaculture model, the application of bioremediation technology to aquaculture does not increase the aquaculture yield by using a large number of high-nutrient bait and antibiotics, but mainly by bio-ecological measures to repair the damaged pond ecosystem, accelerate the material and energy cycle of the ecosystem, increase dissolved oxygen in the water, improve the water quality and self-purification ability of the pond, and improve the yield and quality of aquaculture, thus realizing the sustainable development of aquaculture.
