Abstract: 本研究主要探討印尼的棕點石斑魚(虎斑)與駝背鱸(老鼠斑),在不同養殖地點及生產規模的經濟分析。研究結果顯示在峇里島養殖的經濟效益最佳,其累積流動資金為USD 30,086.25美元,淨現值NPV為USD 17,095.68美元,益本比(B/C)大於1。大型養殖規模的5年計畫經濟效益為USD 64,340.63美元的累積流動資金;淨現值NPV為USD 36,981.98美元;益本比(B/C)為1.33;內部報酬率IRR為157%;回收週期為0.57年。本研究的經濟分析結果指出,在印尼各地區養殖的駝背鱸皆達到經濟效益。此外,各種生產規模的駝背鱸,其累積流動資金及NPV > 0,B/C > 2,IRR > 300 % 及回收週期為 < 1年。 棕點石斑魚的放養密度若增加,會降低攝食率及飼料生產力,對棕點石斑魚生物經濟亦會產生負面影響。養殖駝背鱸若放養較大尺寸的魚苗,對魚苗的生產力具有負面影響。要提昇養殖虎斑的利潤,未來在放養密度及魚苗尺寸之管理方面,還有改善的空間。
This study presents an economic analysis of tiger and humpback groupers at different locations and production scales in Indonesia. The results highlight Bali incurs cumulative cash flow USD 30,086.25, net present value USD 17,095.68, B/C > 1 and the best location with regard profitability. Large-scale farming is economically viable enterprise with a 5 year projected cumulative cash of USD 64,340.63; a NPV of USD 36,981.98; a benefit cost ratio of 1.33; an internal rate of return of 157%; and a payback period of 0.57 year. Financial analysis of humpback grouper farming reveals all locations to be economically viable. The economic analysis of humpback grouper at different production scales highlight a positive cumulative cash and NPV, a B/C > 2, an internal rate of return > 300% and a payback period < 1 year. An increase stocking density in tiger grouper farming produces negative effect on feeding and reduces feed productivity. Management of increasing stocking density has negative effect on tiger grouper bioeconomic mechanism. Stocking larger fry size in humpback grouper farming triggers negative effect on fry productivity. Finally, management of stocking density and fry size in grouper farming has more space to improve in future to increase profitability.
