The "Fishery Technology Talent" is the key motivation of Taiwan's fishery development. During the early post-war era, Taiwan was in the stage of regime change and the repatriation of the Japanese fishery talents has resulted in a stagnant period of fishery development. At this time, the local Taiwanese fishery talents cultivated by Japanese have become the main force for guiding the restructuring development of the fishery throughout the island. Nevertheless, the former "Taiwan Fishery History" theory structure predominated by government either tended to exaggerate KMT government's strong leadership or intentionally ignored the fishery infrastructure under Japanese rule, talent cultivation and the construction of system management. Based on the viewpoints of education, industry takeover and technological talents, this study attempted to discuss how prewar China and Taiwan under Japanese rule cultivated fishery talents through fisheries education and further influenced the overall development of Taiwan's fishery industry according to the overview of the fisheries education in prewar Taiwan and China, fishery industry takeover during the early post-war period, employment and designation of the local fishery technology talents, and the analysis on the number of fishing crafts during the early postwar period. However, how Taiwanese and Japanese skill, research and management talents and fishing crafts cooperated with China takeover and technology teams to form a tricky interaction and cooperative process among Taiwan, Japan and China in Taiwan? How these three powers actually extensively affect the fishery development throughout the island during the early post-war period? Moreover, what are the impacts on Taiwan's fishery development in the early post-war era? In the meantime, this study also reviewed the "Taiwan Fishery History", which has been predominated by government for a long time, and re-defined the role of local Taiwanese fishery technology talents through the restructuring process of Taiwan's fishery development in the early post-war era.
