The structure and production of macrozoobenthos biocenosis in Uzinsky gulf of Sursky water basin

Biotopic distribution of macrozoobenthos was determined and benthic communities were singled out in Uzinsky gulf of Sursky water basin on the basis of observations made in 2004 - 2005. Four biocenoses were found out in the middle gulf area; production values were commuted on different trophic levels for each of them, as well as energy balance components. Macrozoobenthos communities in the middle gulf area participate in forming actual production from 63,17 to 140,49 Kjd/m2, which is able to provide increase of potential fish-benthophags production from 1,95 to 4,32 g/m2 (19,50 - 43,20 kg/hect).
