RESUMO

The paper deals with analysis of morpho-physiological and biochemical indices of perch, pike-perch and ruff from different habitats in winter. Relation between oxygen regime of the water body and content of lipids and glycogen in the tissues was established. On the basis of physiological and biochemical parameters it was shown that among the considered habitats the most favorable for wintering were the mouth area of the Teteriv River, Sobache Gyrlo bay and ponds of Pushcha Voditsa green zone. According to the spleen index and macroergic substances content pike perch was shown to be the most sensitive to unfavorable impact of environmental factors.
