Karadeniz alası (Salmo trutta labrax Pallas,1811)'nın Doğu Karadeniz Bölgesi'nde yumurtalama alanlarının durumu
Bu çalışmada ülkemizin endemik türlerinden biri olan Karadeniz alası (Salmo trutta labrax Pallas, 1811)'m Doğu Karadeniz Bölgesindeki yumurtlama alanlarının (Fırtına Deresi ve İkizdere) bugünkü durumu araştırılmıştır. Araştırma sonucunda Karadeniz alasının İkizdere ve Fırtına derelerindeki yumurtlama alanlarının kirlenme, kaçak avcılık ve dere yataklarının tahrip edilmesi sonucu bozulduğu tespit edilmiştir.
