The snails were placed in two separate treatments called G1 (28.00-33.99 mm) and G2 (34.00-39.99 mm) at the artificial hatchery. Mean shell height and live weight were 32.22±0.06 mm and 8.96±0.07 g in G1; 35.40±0.06 mm and 11.76±0.09 g in G2, respectively. The spawning rate in G1 was lower than G2 (p ≤ 0.05). The survival rate was 78.18% in G1 and 81.14 % in G2 after spawning; 86.63% in G1 and 94.12% in G2 after hibernation, respectively. The mean egg weight was 0.04 g in G1 and 0.05 g in G2 while the shell height and live weight of juvenile were 5.56±0.05 mm and 0.06g in G1; 5.81±0.07 mm and 0.07 g in G2, respectively. The results showed that larger eggs were laid by bigger size adults and after hatching bigger size juveniles were obtained due to larger egg diameter. In addition, the results of experiment confirmed the hypothesis suggested about survival that newly matured individuals could have insufficient energy reserves while larger ones can not withstand the excess energy for reproduction. Thus, the body size of C. aspersum is correlated with reproductive performance and survival rate. © 2018, BIOFLUX SRL.
