Assessment of water bodies located near the cities is one of the important tasks of monitoring. This
is connected with great interest to the study of populations of silver crucian in Lake Kenon. Fish may
quickly respond to anthropogenic pollution of the environment. Silver carp as one of the many species
living in Lake Kenon can serve as a test-object for assessment of the lake ecosystem. A long-term study
of the fish fauna allowed us to reveal various changes of morphological indicators, which are likely
caused by the change of environmental conditions formed under the influence of anthropogenic factors,
additional heat relief, changes in the hydrological and hydrochemical regime. We investigated
abnormalities in the structure of the external and internal organs of crucian carp in some water bodies
in the basin of Lake Kenon. The paper provides a list of registered anomalies. Abnormalities of the fins,
caudal peduncle, gonads, scales were common. Changes in the environmental situation have effect on
the population of silver crucian carp, change in the linear and weight growth naturally occurs. In this
connection, the comparative materials on the growth of crucian carp in ponds with different degree of
anthropogenic load are very important.
