A BRIEF REVIEW OF MAJOR FISHING AREAS IN THE PACIFIC OCEAN
After the peak total catches of over 26 million t observed in the late 1980s, total landings in Area 61 declined from 25.7 million t in 1990 to 24.8 million t in 1993. The main fisheries in Area 61 are: salmon, flatfishes, cods, Alaska pollock, croakers, seabreams, Pacific sandlance, Atka mackerel, filefishes, Pacific saury, Japanese jack mackerel, scads, amberjacks, pomfrets, herrings, Japanese pilchard, anchovies, tuna and tuna-like species, hairtails, chub mackerel, sharks and rays, crabs, prawns, shrimps, oysters, mussels, scallops, cockles, Japanese carpet shell, clams and cephalopods. Landings of bony fishes not included above was 5,362,532 t in 1993. During that period, landings of Japanese sardine and Alaska pollock dropped by 2.24 million t and 678,000 t respectively. These declines were, to some extent, counterbalanced by increased landings of certain invertebrate species, principally Japanese flying squid, Japanese scallop, and Japanese clam. Landings of Japanese anchovy, largehead hairtail, chub mackerel, and Pacific cod also increased, though to a lesser extent.
In 1991, reported increases in marine landings (up some 150% from 1982) meant that China exceeded Japan in catch volume for the first time, and in 1992 the apparent gap continued to widen. The increases in landings for Japanese scallop, Japanese anchovy, largehead hairtail and chub mackerel for Area 61 were due to increased catch by China. The increase in total landings of Pacific cod was due to increased landings by the Russian Federation and Japan while Japan and the Republic of Korea increased landings of Japanese flying squid. The over-exploited state of the Alaskan pollack fishery, especially in the Okhotsk Sea and Nemuro Strait areas, has become more apparent, and the trend towards an increasing proportion of landings consisting of low value, undifferentiated fish has continued.
