Squalius cephalus (L., 1758)’ un Nor Fenotipi Ve Sucul Ortam Ekotoksikolojik Çalışmalar Açısından Değerlendirilmesi (Kastamonu Beyler Barajı Populasyonu)

Abstract

 Su ekosisteminde toksik, kimyasal ve diğer beşeri etkenlerin sitogenetik etkilerinin izlenmesi için balık uygun bir biyoindikatördür. Cyprinidae familyası Beyler Barajı (Kastamonu) Squalius cephalus (L.1758) populasyonlarının “One-Step” metoduna göre belirlenen NOR fenotipi subtelo ya da akrosentik kromozomun kısa kollarında nokta şeklindedir. Genom başına düşen NOR sayısı ikidir. NOR nehir havzalarında kirletici karışımların biyolojik etkilerini değerlendirmek ve sucul ekosistemlerin ekolojik durumunu daha iyi karakterize etmek amacıyla kullanılabilir.
