Abstract:

Pond culture is the main business model of aquaculture in China, which plays a significant role in the development of aquaculture in China. In the pond culture system, nitrogen and phosphorus are essential nutrients for plants in the water. Exploring their balance is an effective method to evaluate the utilization efficiency, conversion efficiency and aquaculture pollution level in the pond culture system. This paper summarized the nitrogen and phosphorus budget and the utilization rate of nitrogen and phosphorus by aquaculture organisms in the pond culture system. It analyzed the significance of the research on nitrogen and phosphorus budget in the pond culture system, and provided a reference for reducing nitrogen and phosphorus deposition in the water, improving the utilization rate of nitrogen and phosphorus by aquaculture organisms, further optimizing the aquaculture model, and reducing the pollution to the ecological environment.

Key words: pond culture, nitrogen and phosphorus budget, nitrogen and phosphorus cycling, utilization rate of nitrogen and phosphorous, optimize aquaculture mode
