| Summary: | 碩士 === 國立臺灣海洋大學 === 水產養殖學系 === 92 === Aquaculture is a multiindustry. The development of aquaculture may be strongly affected by the factors including biology, environment, economics and politics. To evaluate the Rana tigrina rugulosa farming profit, the production cost and revenue were studied under varied culturing techniques.
The study indicated that seasonal production and farming location have significant effect on this business cost and revenue. Productions in seasons one and two were more profitable duo to shorter production time and lower cost. The profitability (a ratio of net profit per one-dollar cost) obtained from indoor farming system ware better than that of outdoor’s. the unit production of indoor system was also higher than that of outdoor system because of higher stoking rate but similar survival rate. However, the production cost of outdoor farming was lower than that of indoor one.
Generally speaking, the profitability of Rana tigring rugulosa farming was affected by its biological characteristics and feeding cost. The future research should focus on the study of optimal conditions such as growing conditions, stocking density and survival rate. Additionally, a study of proper diet formula will definitely have significant effect on the farming profitability.
