Abstract :In this study, the spawning period, length at first sexual maturity and fecundity of the pike insert ignore into journalissuearticles values(Esox lucius L., 1758); population in Lake Karamık between March 2002 and February 2003 were investigated. Mean length at first reproduction insert ignore into journalissuearticles values(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 insert ignore into journalissuearticles values(F); - fork length insert ignore into journalissuearticles values(L); and Fecundity - weight insert ignore into journalissuearticles values(W); relationships were estimated as F = 2.8963 L2.3722 insert ignore into journalissuearticles values(r = 0.590); and F = 58.998 W0.9354 insert ignore into journalissuearticles values(r = 0.668);, respectively. Mean egg diameter was 2.08 ± 0.07 mm.
