APPENDIX IV APPENDIX IV 
As shown above, although cod, pollock and mackerel made 
up about 40 percent of Japan's total 1974 catch, they repre- 
sented only 10 percent of its value. On the other hand, 
mollusks and tunas, making up only 11 percent of the catch, 
accounted for 25 percent of its value. 
Trends in catch quantity from 1970 to 1974 showed sub- 
stantial increases in the harvest of Alaskan pollock (1122.1 
million pounds), sardines and herring (740.7 million pounds), 
skipjack and frigate mackerel (313.1 million pounds), flounder 
andshalabue, (Gis45 5 mil ivonspounds)), cunas (27.9) mslaen 
pounds), and marine cultures including yellowtail, oyster and 
seaweed (729.7 million pounds). Significant decreases were 
shown in the harvests of anchovy (171.9 million pounds) and 
mollusks (176.4 million pounds), primarily common squid and 
octopus. 
According to Japan Fisheries Agency officials, prelimi- 
nary statistics indicate that Japan's total 1975 catch de- 
creased about 7 percent from the 1974 level, due mainly to 
declines in cultures and distant water fishing. 
PROCESSING FACILITIES 
Japan operated 14,400 fish processing plants in 1971, a 
reduction of 18 percent since 1961.1 Older plants were 
closed because they did not meet pollution control require- 
ments and the remaining plants were enlarged and improved. 
The most notable processing improvement in recent years has 
been a greatly expanded capacity for storing fish, both on 
land and at sea. 
Fish processing plant workers are unionized. The 
workers' salaries are based on the negotiations between their 
unions and the processing plants. 
DOMESTIC USE OF FISH PRODUCTS 
In 1974 Japan processed 14,812.7 million pounds of fish 
Or 62 percent of the total catch. Eighty-three percent of 
the processed fish was used for food, 12,279.6 million pounds, 
and the remaining 17 percent was used for nonfood products,

The principal fishfood consisted of frozen, 53 percent, 
fish sausage and cake, 21 percent, and canned, 7 percent. The 
nonfood fish products were processed into fertilizer, 84 per- 
cent, and fish oils and fats, 16 percent.

— These were plants located on land. The fishing fleet also 
processes fish at sea.
