In this study, body weight, egg properties and their relationship were investigated in Astacus leptodactylus (Eschsholtz, 1823)
in spawning season in Ulugöl of Bafra Fish Lakes. In the experiment mean weight of female individuals were obtained as 40.89
g, mean total egg weight 3.16±0.27 and unit egg weight 0.018±0.001 g. In additional average number of eggs were found to be
178.07±13.69, average number of eggs for per unit live weight 4.36±0.30 ind./g and mean diameter of egg 2.11±0.05 mm were
found in female individuals. In the experiment relationships between total weight and total weight of egg (r=0.74), total weight
and number of eggs (r=0.52) total weight of egg and number of egg (r=0.72), number of eggs and number of eggs for per unit live
weight (r=0.84) were found significant (p<0.05).
