Özet

The reproductive characteristics of the pike perch (Stizostedion lucioperca (L., 1758)) population of Eğirdir Lake were examined Age group I and II were the largest population groups Sexual maturity in both sexes was determined in age group I-II. Length in sexual maturity for both sexes was very similar. The spawning period takes place from April to June. Mean egg diameters waried from 0.70 to 0.80 mm. Mean individual fecundity varied from 14066 to 123624. The relationships between fecundity (F) - length (LF), weight (W) and gonad weight (GW) were estimated to be logF= - 1,71813 + 3,55826 logLF, LogF= 1,89837 + 1,10240 logW and LogF= 3,64937 + 0,83832 logGW.
