抄録: This paper describes the history of the trawl fisheries which had operated in the East China Sea and the Yellow Sea from the Second World War until the 1960's. A socio-economic view point in terms of the number of boats, capability of the boats, fish production and productivities, fishery management, regulation and policy of the fishery business, relationships with neighboring countries, and the trend in fish resources was employed. Historical developments were divided into three stages during the period according to the level of fish production. The first stage ranges up to five years after the war. The trawl fisheries of both types of otter and two boats rapidly recovered up to 200 thousand tons beyond the prewar total through political support in spite of a lack of fishing materials under the controlled economy and restrictions of the fishing grounds by the Allied Forces. The rapid development caused irregular fishing following a reduction of boats. In the second stage of the 1950's, the trawl fisheries had further developed and reached to a peak of 350 thousand tons. It was achieved by technical advancement, the abolition of the Allied Forces-restrictions, conclusion of the fisheries agreement with China from which Japan was granted secure fishing, and Korea settling the dominion zone to exclude Japanese boats. Big fisheries companies had collected the boats. During the 1960's in the third stage, the trawl fisheries hadn't developed anymore due to limitations of the fish resources. The amount of fish production became stagnant at around 300 thousand tons under the circumstances with a decreasing number of boats instead of their enlargement and change from broadside type to stern type in drawing up the net, conclusion of the agreement with Korea which brought secure fishing and an expansion of the fishing grounds. On the other hand, the otter trawl had turned from these seas to other distant waters with more profitability. As a result of resources limitations, target species changed from a material for fish paste to fresh fish. Fishery management grew worse due to the high rise of the operating costs against the gradual rising income and lack of labors.
