The Eastern Bering Sea Shelf The Eastern Bering Sea Shelf : oceanography and resources / edited by Donald W. Hood and John A. Calder easternberingsea00hood Year: 1981 GREENLAND TURBOT AND ARROWTOOTH FLOUNDER E3<,00m, Ea, m, Figure 60-9. Distribution of Japanese catches of Green- land turbot and arrowtooth flounder in 1977. The small flounders, mainly yellowfin sole, rock sole, flathead sole, and Alaska plaice, are mainly confined to the continental shelf. These species, except for flathead sole, perform extensive migra- tions, onshore in spring and offshore in fall. Con- centrations of these species, as catch statistics show, depend on the seasonal timing of the fishery. In 1977 the target fishery for yellowfin sole was in January-February and September-December. In these periods, the largest catches of yellowfin sole were taken east of the Pribilof Islands (Fig. 60-10). Catches of other small flounders consist mainly of rock sole and flathead sole, but include a number of other species such as Alaska plaice, starry flounder, longhead dab, and rex sole. These species are taken incidentally in the pollock and yellowfin sole fisher- ies. Concentrations of these species in Japanese catches in 1977 were widely distributed from depths of less than 100 m off Bristol Bay to near the shelf edge northwest of the Pribilof Islands (Fig. 60-11). Catches in shallower regions of the southeast Bering Sea were principally rock sole and Alaska plaice, and those in deeper waters of the southeast Bering Sea and northwest of the Pribilof Islands were princi- pally flathead sole and rock sole.
