<abstract xmlns="http://www.w3.org/1999/xhtml">The aim of this study was to determine the growth features of European perch (<italic>Perca fluviatilis</italic> L., 1758) inhabiting Lake Ladik. A total of 858 individuals were caught. The total length and weight ranged from 8.2 to 27.5 cm and from 7.16 to 365.20 g, respectively. The age of the females ranged between 1 and 7 years and the age of the males ranged from 1 to 5 years. The female to male ratio was 1:0.19.
