Generalized assessments of composition, quantitative distribution and biomass of benthic macrofauna on the shelf and slope in the North-West Pacific
Quantitative information on the bottom macrofauna of the continental shelf and slope down to the depth 2025 m is generalized for the Far East of Russia and the adjacent waters of North Korea and Japan (in total 32,700 bottom trawls obtained in 224 expeditions over the area about 2 million km2 in 197...

The Okhotsk and Bering Seas have the higher biomass mainly because of their vast areas, but the density of macrofauna is ranked in other order: the Pacific waters of Kamchatka (64.5 t/km2, without jellyfishes - 18.7 t/km2) - Pacific waters of Kuril Islands (27.1 t/km2) - Bering Sea (24.5 t/km2) - Okhotsk Sea (16.5 t/km2) - Japan Sea (11.7 t/km2).

The areas with narrow shelves and sharp slopes, steep and patchy relief, are usually denser populated. However, the Japan Sea has the lowest biomass and density of benthic macrofauna, possibly because of lower productivity.
