| Özet |
| The purpose of this study was to investige the reproductive success of land snails (Cornu aspersum) without photoperiod during the non-breeding season in the Black Sea Region between December 2019 and January 2020. Snails, which were placed in cold storage for a hundred days, were awakened in December. The reproductive performances were assessed under semi-controlled laboratory conditions using the natural daylight cycle and the ideal temperature and moisture. The experiment was designed as a single group with 3 replications. The experiment was designed 3 replications, with 10 snails in each replicate in total of 30 snails. The reproductive performance of the snails was observed daily and the first mating took place on the 9th day of the study and the first egg-laying was detected in the second week of the study. The fecundity of the snails was 43%. Spawning activity was continued through to 3 weeks. The mean number of eggs, hatching rate and the number of offsprings were 151.13±22.02, 90.33±2.39% and 138.13±21.09, respectively. The mean egg and offspring live weights were 0.034±0.001 g and 0.03±0.007 g, respectively. The findings showed that the reproductive performance was low. In conclusion, reproductive performance is unsuitable for commercial snail production without the photoperiod treatment during the non-breeding season. |
