The primary focus of energy development in various countries is to develop green energy and reduce carbon emissions. The western side of Taiwan receives intensive sunlight and has extensive aquaculture areas, making the development of fishery electricity symbiosis highly promising. However, research on the embanked solar photovoltaic systems are still not well developed. This study compares the differences in water quality between clam ponds in embanked photovoltaic systems and traditional aquaculture. The results indicate that the average temperature in integrated systems was 1.55°C lower than traditional ponds, while the average dissolved oxygen was 0.03 mg/L higher in integrated systems compared to traditional ponds. In terms of average pH levels, integrated systems showed an increase of 0.32 value compared to traditional ponds. Integrated systems exhibited a higher average salinity value, with a difference of 10.55 psu compared to traditional ponds. Finally, it was observed that the average ORP in both groups tended to stabilize, but traditional ponds showed a higher value by 12.63 mV compared to integrated systems. In summary, this type of fishery–electricity symbiosis not only improves water quality stability but also simplifies aquaculture management and equipment maintenance.
