Physiological Adaptations in Juvenile Dolly Varden Salvelinus malma (Salmonidae) Dwelling in Polluted Rivers of Kamchatkan Volcanic Territories

Аннотация

Biochemical status of riverine juvenile Dolly Varden was defined under the dissolved toxicants and mineral suspension excess concentration impact. The processes of toxicants bioaccumulation, metabolism activation, dynamics of oxidative stress and detoxification were examined in a wide range of natural chronic pollution intensity. Background conditions variability and critical toxicants levels in the polluted habitats were determined. Physiological response specificity was found for juveniles of anadromous and landlocked Dolly Varden.
