 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.
