Individual Effects of Hydrostatic Pressure and Hypoxia on Lactate Dehydrogenase Activity in Tissues of Fishes with Different Parameters of Locomotor Function

RESUMO

Cytoplasmic lactate dehydrogenase (LDH) activity in the liver and muscles of Black Sea fish (Scorpaena porcus, Diplodus annularis, and Trachurus mediterraneus) was studied after short-term differential exposure to higher hydrostatic pressure (3 MPa) and autogenous hypoxia. LDH activity, specific for each tissue, proved to be very sensitive to the effect of high pressure and changed depending on the time of exposure to this factor. The degree of changes correlated with natural locomotor activity of the studied fish species. Hypoxia had no apparent effect on enzyme activity in tissues.
