During the expedition, ichthyological materials haev been collected from 45 stations consisting of 9 sections. It has been determined that due to the changed environmental conditions in the Caspian Sea in recent years (declining sea level, exposure to heavy pollution, etc.), the condition of marine fish Clupea, Planiliza and Clupeonella) living in the Caspian Sea is satisfactory, on the contrary, transient and semi-transient fish (Normal Carp, The Caspian roach, Common Bream and Shamai) condition is not satisfactory.
