Özet

In this study, the spawning period, length at first sexual maturity and fecundity of the pike (Esox lucius L., 1758) population in Lake Karamik between March 2002 and February 2003 were investigated. Mean length at first reproduction (Lm) was determined as 19.7 cm for female pike. The monthly values of the gonadosomatic index indicated that spawning occurred between February and March. The relative fecundity was determined as 45.7 ± 4.9 eggs g-1 total body weight. Fecundity (F) - fork length (L) and Fecundity - weight (W) relationships were estimated as F = 2.8963 L2.3722 (r = 0.590) and F = 58.998 W0.9354 (r = 0.668), respectively. Mean egg diameter was 2.08 ± 0.07 mm. © TÜBİTAK.
