Description

Mariculture pond

Technical Field

Background

Pond culture plays a significant role in the aquaculture industry in China as an important mode of land-based culture. The stable water quality environment and the healthy substrate environment are the key factors for determining the success or failure of the pond culture production. For mariculture ponds, the input of a large amount of fresh water caused by rainfall has a particularly significant effect on the water quality of the mariculture pond. Continuous rainfall can lead to the reduction of pond water temperature, and the speed of material circulation and energy circulation is slowed down to lead to the reduction of dissolved oxygen at the bottom of the mariculture pond, make the disease resistance of aquaculture animals in the mariculture pond decline, still can appear plankton density and quality reduction and harmful algae breed and lead to a series of negative problems such as the ageing of mariculture pond water. If heavy rainstorm occurs, a large amount of fresh water is input into the mariculture pond in a short time, and if the large amount of fresh water input into the mariculture pond is discharged in time, the salinity and osmotic pressure of the pond water can be changed violently, and huge survival threat is directly caused to cultured organisms.

Moreover, in continuous rainy or heavy raining days, the salinity of natural seawater is low and is not enough to replenish the salinity of the aquaculture water in the pond. In addition, some mariculture ponds discharge surface layer fresh water in a mode of laying pipelines at the bottom and the surface layer of the mariculture pond, the mariculture pond has the problems of complex internal pipeline laying work and high subsequent maintenance cost, and meanwhile, the pipeline radiation action area of the mariculture pond is small, so that the desalination efficiency is low.
