|Abstract: ||本研究旨在了解不同石斑魚生產之經濟效益與市場行情，因此將取自台灣之「青斑」、「龍膽石斑」養殖戶與取自印尼之「老虎斑」、「老鼠斑」養殖戶之生產成本與獲利資料進行統計分析，並調查石斑魚主要消費市場—中國之市場售價，以了解品種別石斑魚行情。 多變量變方分析結果顯示，四種石斑魚品種之「單位生產成本密度變數」、「每年單位生產成本密度變數」與「益本比變數」皆有顯著的差別。馬式距離結果顯示，在單位生產成本密度變數與每年單位生產成本密度變數上，各品種間皆具有顯著的差異，以青斑、老鼠斑間之差異最大，益本比變數中，龍膽石斑與老虎斑間之益本比則無顯著差異。區隔函數結果顯示，青斑的管銷成本高於其他三種石斑魚，而老虎斑則是以人事成本較高，老鼠斑的種苗益本比及餌料益本比高於其他三種石斑魚。石斑魚品種別中國市場售價由高至低依序為老鼠斑、東星斑、藍瓜石斑、油斑、老虎斑、金錢斑、龍膽石斑、青斑。中國青斑售價與台灣之價差高達700元/公斤。 據此，欲提高台灣石斑魚養殖產業之經濟效益，青斑可從降低管銷成本上著手。台灣生產之青斑、龍膽石斑售價較低，未來可朝向養殖更高價之石斑魚品種。中國市場售價高昂，若能在中國設立銷售據點，將可提高生產者之收益。|
The objective of this study is to evaluate the profitability of varied grouper farmings. The structure of cost and return in producing Epinephelus malabaricus、E. lanceolatus、E. fuscoguttatus and Cromileptes altivelis, were investigated and analyzed. The result of MANOVA (Multivariate Analysis of Variance) indicated that varied species had significant effect on not only cost but also BCR(benefit-cost ratio) of production. The result of Mahalanobis Distance analysis indicated that BCR between E.lanceolatus and E.fuscoguttatus was not significant different. The result of discriminant function analysis showed that miscellaneous cost of E. malabarricus was higher than that of the others. The most expensive grouper was C. altivelis, and the cheapest one was E. malabarricus. The price of E. malabarricus in China was 700NT/kg higher than that in Taiwan. As the result, the E. malabarricus farming should reduce the miscellaneous cost. Since the difference of BCR between E.lanceolatus and E.fuscoguttatus was not so different, the farmers of E.lanceolatus may switch to produce E.fuscoguttatus which had a shorter production cyale. The market prices of groupers in China were usually higher than that in Taiwan. As the result, Taiwan farmers may take a share of China market to improving their profitability.
