Distribution of benthos biomass in Kara Sea (g/m3) (Filatova and Zenkevitch). complete absence of fish within the area of brown muds (which might justifiably be called the Ashless sea) is explained by the general lower productive properties of this body of water and by the brown mud possessing conditions unfavourable to fish-life. The benthos biomass of the Kara Sea brown mud is twenty times lower than the average Barents Sea biomass; the productivity difference, however, is still more marked, since the processes of biological plankton production are almost suspended for 8 to 9 months and as a consequence all the links of the food chain are slackened. The lowering of productive properties of the Kara Sea.
