Cultivating fisheries talent in the smart fisheries era: the case of fisheries vocational high schools in Taiwan

As one of the fastest-growing sectors in global food production, aquaculture has raised increasing concerns about its environmental impacts. This study is the first to conduct a life cycle assessment (LCA) of the China’s Manila clam (Ruditapes philippinarum) supply chain, focusing on the stages of seed rearing, farming, and processing, and comparing the environmental impacts of south-north relay aquaculture and northern seed rearing-farming supply chains. The LCA results indicate that Marine Aquatic Ecotoxicity Potential (MAETP) accounts for the highest environmental burden among all impact categories. In order to the high electricity consumption, seed rearing stage has the highest environmental impacts. Moreover, the south-north relay aquaculture supply chain has an environmental burden due to long-distance transportation; therefore, the northern seed rearing-farming supply chain is a more sustainable strategy and local seed rearing in northern regions was recommended. Further analysis reveals that energy consumption is the main sources of environmental impact in the whole supply chain; two energy improvement scenarios are proposed: scenario 1 (photovoltaic power generation and diesel-powered transport vessels) and scenario 2 (wind power generation and diesel-powered transport vessels). The simulation results demonstrate that these scenarios could reduce the environmental impact potential of the supply chain by 80.51% and 82.32%, respectively. The application of renewable energy will significantly decrease the environmental burdens and provide useful measures to the sustainable development of the Manila clam supply chain in China.
