Abstract: This study analyzes the current development status and existing problems of the fishery-photovoltaic complementary industry in Tianjin city. Based on survey data from 38 completed and 33 under-construction projects across 7 districts, the results show that the total area of completed projects in the city reaches 2 889.53 hm2, with the photovoltaic component accounting for 86.98%. The total installed capacity is 3 025 MW, which is estimated to reduce carbon dioxide emissions by 1 010.63 million tons over a 25-year operational period. Fishery-photovoltaic complementary projects significantly enhance land output efficiency through “Fishery-Power Sharing”, improve the income structure of fishermen, and promote the utilization of clean energy. However, issues such as the impact of shading from photovoltaic panels on the aquatic ecology and inconveniences for aquaculture operations still need to be addressed. It is recommended to strengthen theoretical and technological research, optimize photovoltaic layouts, improve environmental monitoring, refine installation methods, breed shade-tolerant species, enhance supporting policies, increase financial and land support, and promote the sustainable development of the industry.
