Abstract
Aim. The aim of the given building paper is to expose morphobiological peculiarities of Russian Sturgeon, and also the investigation of hydrocarbon accumulation in organs and tissues in sturgeon species.
Location. The Caspian Sea
Methods. Conventional methods of ichtyological investigations were used.
Results. Distinctly expressed trend of interyear dinamics, characterized by gradually decrease from 1999 by 2006 of the general content of hydrocarbons and aromatic fraction in organs and tissues of sturgeon has been exposed on the basis of analysis of data obtained during autumn investigations.
Main conclusions. The investigations conducted showed that in mascular tissues of sturgeons (according to average indeces for many years), the content of aromatic hydrocarbons is lower than in muscles of sturgeons. The degree of hydrocarbon accumulation at in museles doesn’t only determine the consumer value of hydrobionts, but also the depth organism affection. Their accumulation in gonads characterizes possibility of reproductive functions of sturgeon population disturbance.
