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).
