Annotation:
The authors of the article present the description of the ichthyo-fauna indicating fisheries zone category and food potential in the Okhotsk Sea, Kara Seas, and the Gulf of Ob within the boundaries of the planned wells construction. The consequences of direct and indirect negative impacts on aquatic biological resources and their habitat during excavation work in the water area, installation of building structures and water intake are described as well. Based on previously completed impact assessments on aquatic bioresources and their habitats during the design of offshore well-drilling, The impact on the state of planktonic and benthic communities and juvenile fishes was analyzed when positioning SSFDR "Severnoe siyanie/Polyarnaya zvezda", JUDR "Arkticheskaya", IRFP "A" at the work site and drilling wells from the point of view of the earlier performed estimations of the impact on water bio-resources and their habitat, when designing wells construction on the shelf. The species of fish recommended by the Federal Agency for Fisheries for carrying out compensatory measures in the Ob-Irtysh and Far Eastern fishery basins are indicated.
