Sıcaklığın kalamar (Loligo vulgaris Lamarck,1798) yumurtalarının gelişimine ve inkübasyonuna etkisi

Bu çalışmada, farklı sıcaklıklarda inkübe edilen kalamar (Loligo vulgaris Lamarck, 1798) yumurtalarının embriyonik gelişim süresi ve açılım başarısı incelenmiştir. Bu amaçla, 4°C aralıklarla 10-22°C arasında, toplam 8 deneme grubu kurulmuştur. Denemelerde, balıkçılardan temin edilen, safha 13 (IV)'teki kalamar yumurtaları kullanılmıştır. Yumurtaların en fazla ve en az yumurta açılım başarısı ve embriyonik gelişim süresi, Y denemesinde sırasıyla, %86.9-73.5 ve 43-23 gün, K denemesinde ise sırasıyla, %88.5-79.7 ve 39-20 gün olarak hesaplanmıştır.

Effects of temperature on development and incubation of squid (Loligo vulgaris Lamarck,1798)

In this study, embryonic development time and hatching success of squid (Loligo vulgaris Lamarck, 1798) eggs, which were incubated at different temperatures, was investigated. In this purpose, total 8 experimental groups were performed at each 4 degrees of temperatures between 10°C and 22°C. The egg capsules in stage 13 (IV) which were obtained from fishermen were used in the experiments. The maximum and minimum hatching success and duration of embryonic development of the eggs were estimated as 86.9-73.5% and 43-23 days, respectively in experiment Y, and as 88.5-79.7% and 39-20 days, respectively in experiment K.
