Peculiarities of Adaptation of Fish to the Oil Pollution of the Aquatic Environment

M. O. Mironiuk
Institute of Hydrobiology National Academy of Sciences of Ukraine, Kiev

ABSTRACT

The effect of the crude oil (concentration from 5 to 30 maximum permissible concentrations (MPC)) on activity of succinate dehydrogenase, transamination enzymes and glycogen content in the tissues of carp has been studied. Suppression of the succinate dehydrogenase link of the respiratory chain was noted, which plays an important role in compensatory adaptation of the fishes’ energy metabolism to this toxicant. It was stated that under considered oil concentrations glycogen content in liver increased and its content in the muscles decreased. Disturbances of the protein metabolism were revealed, exhibited as decrease of the transamination enzymes’ activity in the fish organism.
