| Research Abstract |
The energy analysis of fishing industry is considerably benind that of agricultural one. We have worked on the squid angling, which we here adopt as a good example of much energy consuming industry from the energy analysis viewpoint. Using the "reports of energy economy survey", analyzed the secular variation for the past 30 years and conduct a case study about a specified fishing boat. The results are as follows;
A fishing boat that fished offshore New Zealand and offshore Falkland Islands was subjected to analysis. A quantitative model which describes effct of OPUE(kg/h line) on fuel unit (kl-kg) is proposed. His model shows that fuel unit depends strongly on CPUE when CPUE is small. In fishing grounds of small CPUE, fuel consumption by main engine occupied a large part of fuel unit, on the other hand, in fishing grounds of large CPUE, fuel consumption by auxiliary engines for refrigerators and fishing gears except fish lamps was dominant. Ratio of fuel consumption by fish lamps ranged from 10 20. Average total fued consumption per unit catch was 5.51 x 10^<-4> kl/kg and average CPUE was 9.76 kg/h line.
