The actual situation of the small boat fisheries in the coastal area was studied by the principal component analysis. The data were collected for five years (1977-1981) from Iwa-wada Fisheries Cooperative whichi s located in the middle of Chiba Prefecture along the Pacific coast.
The results obtained are as follows:
The highest income was observed in the fishing boats in which main fish species caught were skipjack, tunas and squids. The boats which caught mainly yellowtails were ranked in the middle. The lowest rank was shown in the boats which caught fluonders, as well as miscellaneous species by the trammel net.
