A method for preventing chilling injury of an aquaculture pond is described, which includes the following steps. A heat exchanger is disposed within an aquaculture pond. The heat exchanger includes an inlet and an outlet. At least one portion of the heat exchanger is immersed in pond water within the aquaculture pond. Groundwater is pumped out of an aquifer and is introduced into the heat exchanger through the inlet. The groundwater flowing out of the heat exchanger from the outlet is pumped into the aquifer.一種防止養殖池寒害的方法,其包含下列步驟。設置一熱交換器於一養殖池內。此熱交換器包含一入口與一出口。此熱交換器之至少一部分浸在養殖池內之池水中。於一地下水層抽取地下水,並經由入口將地下水導入熱交換器中。將由出口流出熱交換器之地下水導回地下水層中。200‧‧‧養殖池202‧‧‧入口204‧‧‧出口206‧‧‧熱交換器208‧‧‧水泵210‧‧‧管路212‧‧‧地下水214‧‧‧地層216‧‧‧地下水層218‧‧‧側面220‧‧‧底面222‧‧‧水井224‧‧‧水井
