| Özet |
| In this research, the growth and survival rate of juvenile Helix lucorum was determined during the eight weeks. Coefficient variation (CV) in assessing variability of shell height and live weigth was investigated. One week old juvenile snails with a mean shell height of 6.73±0.03 mm and a mean weight of 0.10±0.01 g were stocked to the three rearing boxes with a density of 13 snails per group at the start of the experiment. At the beginning of the study, the variability of shell height and live weight showed relatively little difference as 9.71% and 28.16% but this gradually increased towards the end of the study. The final variation of shell height and live weight was calculated 20.32% and 59.84%, respectively. At the end of the study, cumulative survival rate was found 97.74%. In conclusion, snails showed high survival rate with high size variation in the study. Initial stocking density is optimal for rearing juvenile H. lucorum but after four weeks, stocking density should be decreased and thereby lower size variation and more similar growth pattern might be provided. |
