sented. The spatial distribution of the eggs and larvae of almost all encountered species confirms the presence
of drift along the coast with a gradual drift of passive migrants from the coast of eastern Sakhalin into the open
waters. The most diverse and numerous ichthyoplankton was over the shelf zone to the north of 51°00
; the least diverse, from 50°00
to 51°00 N. The minimal proportion of the normally developing eggs of the wall-eyed pollack Theragra chalcogramma and the yellow-finned sole Limanda aspera dominant in catches was recorded
over the oil–gas deposits located in the coastal zone of the northeastern shelf. The coincidence of stations (83%)
with a high proportion of the dead eggs of these fish species can indicate a similar impact on it of environmental
conditions formed in deposit areas.
