Özet
Fangri (Pagrus pagrus) yumurtalarında sıcaklığın embriyolojik gelişim üzerindeki etkisinin saptanması için 10 (8,10,12,14,16,18,20,22,24 and 26°C) farklı sabit su sıcaklığı denenmiştir. Embriyonik gelişim 14-22°C'ler arasında tamamlanmıştır. Regresyon analizleri sonucunda, embıiyonik gelişim ile inkübasyon sıcaklığı arasında negatif ilişki olduğu gözlenmiştir. 8 ve 26°C su sıcaklıklarında hücre bölünmesi meydana gelmemiştir. 10°C'de döllenmeden 5:45 dakika sonra 8 blastomer safhasında total ölüm gözlenmiştir. Bunun yanı sıra, 12 °C'de döllenmeden 42:45 saat sonra % gastrula safhasında ve 24°C'de döllenmeden 4 saat sonra erken blastula safhasında toplam ölümler tespit edilmiştir.
In this study, ten different constant water temperatures (8,10,12,14,16,18,20,22,24 and 26°C) were used in order to determine relationships on effects of water temperature on embryonic development of the red porgy (Pagrus pagrus) egg. Constant water temperatures between 14 and 22°C were found to support successful embryonic development. According to regression analysis, a negative relationship between the rate of embryonic development and incubation temperature was observed. While embryonic development was completed within this range (14-22°C), there was no cell division at water temperatures of 8 and 26°C. Total mortalities were observed at 8 blastomer stage in 10°C at 5:45 h after fertilisation. Also, in middle gastrula stage at 12°C, it was determined 42:45 h after fertilisation and 4 h in early blastula stage at temperature of 24°C after fertilisation.
