There has been no publication on the energy analysis of catching fish for fish paste products. This paper reports an estimation of direct and indirect energy input per kilogram of catch of these fishes, by use of the census of fisheries economics. It was found that the energy input per weight of catch in the fishing of Alaska pollack (distant trawl in North Pacific Ocean) was nearly constant at the level of about 5, 000 kcal/kg from 1967 to 1977. But it increased greatly in the year of 1978. It reached 20, 000 kcal/kg in 1980. On the other hand, the energy intensity in the fishing of croaker and others (trawl in East China Sea) has been gradually increasing year by year. It was 8, 000 kcal/kg in 1967 and 18, 000 kcal/kg in 1980. It was also found that 80-90% of the total energy was consumed as fuel oil by fishing boat in both cases.
