碩士 === 國立中山大學 === 海洋資源學系 === 82 === The deep-sea squid jigging fishery of Taiwan began at 1972 , and the trandational fishing grounds included the New Zealand waters , the northwest Pacific and the southwest Atlantic . The southwest Atlantic was the only squid jigging fishing ground with economic value in 1993 . This study analyzed the profitability and fuel oil average product of 700 ton-class (701-800 tonnage) and 800 ton-class ( 801-1000 tonnage) squid jigging fishery in the southwest Atlantic from 1991 to 1993 . The results were as follows : 1.profitability By means of the present value method , the profitability of 800 ton-class was better than that of 700 ton-class . The reasons were : (1) The average variable cost of the 800 ton-class was about 30-50﹪ higher than that of 700 ton-class , but the former''s fi- shing revenue was about 40-100﹪ higher than the latter''s . (2) Among the direct costs , the fishing oil was the biggest one that averaged 13.51﹪ of the 700 ton-class'' average variable cost. The cooperative license fee was the biggest one that ave- raged 15.56﹪ of the 800 ton-class'' average variable cost. As for the indirect costs , the depreciation was the bigg- est one between 700 and 800 ton-class''. (3) 800 ton-class'' average fish price was about 31.7﹪ higher than break-even price , and 700 ton-class'' had only about 3.7﹪. (4) 800 ton-class'' average fish product was about 33﹪ higher than break-even product , which was much better than 4﹪ higher of 700 ton-class''. 2.fuel oil average product Having analyzed the data , this study got the conclusion that 800 ton-class was superior in fuel oil average product to 700 ton-class due to the following reason : 800 ton-class'' average value of fuel oil product averaged 10.24﹪ , which was higher than 700 ton-class'' 8.63 .
