dc.description.abstractThe 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.
dc.description.abstractBu çalisma, Karadeniz Bölgesinde Cornu aspersum türü kara salyangozlarinin dogal üreme dönemi olmayan dönemde, Aralik 2019-Ocak 2020 tarihleri arasinda fotoperiyot uygulanmadan üreme basarisini gözlemlemek amaciyla yapilmistir. Yüz gün süreyle soguk hava deposunda bekletilen anaç salyangozlar, aralik ayinda uyandirilmistir. Üreme performanslari, dogal gün isigi döngüsü, ideal nem ve sicaklik kullanilarak yari kontrollü laboratuvar kosullarinda degerlendirilmistir. Deneme tek grup ve üç tekerrürlü olacak sekilde tasarlanmistir. Deneme basladiktan sonra salyangozlarin üreme performanslari günlük olarak gözlemlenmistir. Ilk çiftlesme çalismanin dokuzuncu gününde gerçeklesmis ve çalismanin ikinci haftasinda ilk yumurtlama tespit edilmistir. Çalismada salyangozlarin üreme performansi % 43 olarak bulunmus olup yumurtlama aktivitesi üç haftaya kadar azalarak devam etmistir. Ortalama yumurta sayisi, yavru çikis orani ve yavru sayisi sirasiyla 151.13±22.02, %90.33±2.39 ve 138.13±21.09 olarak bulunmustur. Ortalama yumurta ve yavru agirliklari sirasiyla 0.034±0.001 g ve 0.03±0.007 g olarak tespit edilmistir. Çalismadan elde edilen bulgulara göre salyangozlarin üreme performanslarinin düsük oldugu belirlenmistir. Sonuç olarak, dogal üreme dönemi disindaki bir dönemde fotoperiyot uygulanmadan elde edilen üreme performansinin ticari salyangoz üretimi için uygun olmadigi sonucuna varilmistir.
