Recently, by a variety of factors, the yield of O. mykiss decrease continuously. It cannot satisfy domestic market anymore. In order to find the future development trend of the O. mykiss industry, this study aimed at rainbow trout industry and conducted a questionnaire survey to collect the information for both biological and economic side. Using multivariate statistical analysis as the analytic method, try to find out the key factors that impact the production efficiency in the its process. For industrial development strategy, SWOT analysis is applied to clarify the advantage and disadvantage of rainbow troutfarming. Finally, provide the strategies for Rainbow trout of Taiwan farming in future by the results of the production economic and industrial development strategy analysis. This study analyzed production areas difference, run patterns difference, production areas and business interaction patterns. The results showed that O. mykiss culture is at a significant level on production areas difference, biological variables, the cost of production inputs and variable profit. Area of Hsinchu and Miaoli has best overall profit, follow by Yilan County, where Xinbei City is at last. Xinbei City needs to improve both culture environment and feeding technology to raise the survival rate. Yilan County must improve feeding technology to decrease the price of feed and increase the profit. Although area of Hsinchu and Miaoli has best score, they must be careful about the risk of the culture at local, try to minimize the cost of utilities and other stuff. Business patterns, such as compound restaurant, specialized breeding, production cost investment density, and profitability variables, have significant difference at different business mode. Compound restaurant shows better profit than others. In addition, size of the specialized breeding in Taiwan is smaller than foreign. With the raise of sightseeing, farming industry of rainbow trout should transform to compound restaurant pattern, and satisfy domestic market by importing. Finally, for the analysis of the production areas and business interaction patterns, the results show that there are significant difference at biological variables, production cost investment and its density, and no difference at both variable profit and benefit-cost ratio.Compound restaurant is a good choice for Xinbei City and the area of Hsinchu and Miaoli, where specialized breeding is better for Yilan County.At the biological side, survival rate and stocking density have effect on overall business performance. According to the analysis result of the Cobb-Douglas function, the results show that farming industry of rainbow trout has feed and staff issue. The salary of the industry decreases continuously. For the past few years, due to the effect of Global Warming, natural disaster and policy, the farming of O. mykiss culture in Taiwan is gradually decreasing. According to this information, rainbow troutfarming has its own good side and bad side on the production efficiency performance at each area and patterns. The key factors of the production economics are feed and staff so they should improve the feeding technology and staff management to increase the benefit. In future, trout farming should focus on following strategy: master farming techniques and processing advantages, to build its own brand image; develop diversified aquatic products, to create leisure fisheries for sightseeing; set up marketing group and let them operate, to prevent the imbalances on production and marketing; use of various research reports, to assess the future development of the trout industry; strengthen the integration of aquaculture production areas, to assist industrial upgrading and reduce the loss of fish farming. When the industry is more stable and the investment environment is more perfect, it will attract more businesses and resources into the industry chain, which can increase the life of the industrial.
