This study
involves the investigation of the breeding properties of
Esox lucius (L., 1758) living in Kapulukaya Dam Lake in
Turkey. It was observed that the fish reaches sexual
maturity at the age of 3, and the breeding period starts in
February and ends in March. The highest and lowest
gonadosomatic index (GSI) values were determined in February
and July, respectively. The average egg number per fish was
estimated to be 19781.75 ± 12051.09. The relations between
the fecundity (F), body length (L) and body weight (W) were
found as F = 0.00137275 × L2.675 (r = 0.85) and F
= 32.38038307 × W 0.9564 (r = 0.87).
