Biochemical investigations of some Barents Sea commercial fish species in the conditions of man-made pollution

The data of biochemical investigations (period 1998-2003) of some Barents Sea commercial fish species for estimating the status indicator of hydrobionts as components of water ecosystems of the Kola North in the conditions of man-made pollution have been considered in this paper. The analysis of the data has shown seasonal nature of the dynamics of the basic chemical characteristics' contents (water, total protein and amine nitrogen, water-soluble protein, lipids, mineral) and biochemical properties (the activity of proteases) of fishes. The native data have been compared with the previous data of the laboratory of hydrobionts biochemistry of the Polar Research Institute of Marine Fishery and Oceanography by N.M. Knipovich.

Basic tendencies of changing hydrochemical parameters of the Kola Bay aquatic ecosystem in 2000-2011

The results of hydrochemical monitoring of the aquatic ecosystem of the Kola Bay have been presented in the paper. The data of changing content of nitrite, nitrate, ammonium nitrogen, phosphates, ions of iron, silicon have been discussed. Contemporary methods of analysis have been used. The main tendencies of changing these hydrochemical parameters depending on different factors have been analysed.
