In recent years, Taiwan has been promoting the co-construction of fishery green energy industry model, expecting to activate the utilization of aquaculture space, reduce environmental pollution, ensure famer's income and construct innovative fishery management model. The 2025 renewable energy development target proposed by the government in 2015 was to set the solar photovoltaic device capacity to 20 GW. However, it requires massive land to achieve this goal. In 2017, the agriculture green energy strategy of Council of Agriculture has to include land-based aquaculture. This, combining traditional aquaculture process with green energy applications, is to create a green energy co-construction of the economic model. The model will contribute to the promotion of green energy and expect to bring a total benefit for the aquaculture industry. But the different co-construction model even in the technical feasibility of the premise, it may not be able to meet the conditions of market feasibility. Through this project, the economic benefits of green energy co-construction in Clam industry are analyzed to further discuss and evaluate the feasibility of this strategy in the economic and industrial aspects of aquaculture industry. The major production areas in Taiwan are Changhua, Yunlin, Chiayi, and Tainan. For the sustainable development of Clam culture, cultivating fine Clam seedlings and developing cultivation methods and management techniques in response to climate change will be an important topic in the future. In order to improve the possible losses and impacts of extreme climate and the financial situation of breeders, hard clam breeding is expected to be carried out in combination with green energy facilities in order to reduce deaths due to dramatic changes in temperature. Furthermore, in the economical evaluation, fishermen can not only stabilize fishing income but also increase extra income by renting space and solar photovoltaic operators to obtain rental or electricity sales returns. However, most breeders still have many doubts and worries about photoelectric facilities combined with aquaculture, such as environmental pollution, the changes of fishing laws and so on. Afterward, we should actively transform the problems into development focus and priority projects, which will become the key promoting issues for industry, academia and research, therefore, will increase the cognition and importance from relevant industry or public of this issue.
