Keban Baraj Gölü’ndeki Tatlısu İstakozlarının (Astacus leptodactylus Esch. 1823) Dokularındaki Arginaz Aktivitesi Üzerine Kirliliğin Etkisi

Bu çalışmada, Keban Baraj Gölü’nde bulunan Astacus leptodactylus’un dokularındaki arginaz aktivitesi üzerine kirliliğin etkisi araştırıldı. Arginaz aktivitesi, temiz bölge ile karşılaştırıldığında kirli bölgedeki kerevitlerin hepatopankreas (p < 0.05) ve solungaç (p < 0.001) dokularında daha yüksek bulundu. Kastaki arginaz seviyesinde istasyonlar arasında hiçbir fark gözlenmedi. Buna ilave olarak, kirli bölgedeki dişi kerevitlerin hepatopankreas (p < 0.001), solungaç (p < 0.01) ve kasında (p < 0.05), erkek kerevitlerin ise solungacındaki (p < 0.001) arginaz aktivitesinin istastistiksel açıdan daha yüksek olduğu tespit edildi.
