Araştırmada bakır (Cu) ve kurşun (Pb)’un 96 saatlik LC50 değerinin %10’una karşılık gelen derişimlerinin (sırasıyla 4,0 ve 0,2 ppm) 7, 15 ve 30 gün sürelerde etkisine bırakılan Oreochromis niloticus’un Hepatosomatik İndeks (HSI), Gonadosomatik Indeks (GSI) ve Kondüsyon Faktörü (CF) üzerine etkisinin belirlenmesi amaçlanmıştır. Belirtilen parametrelerin hesaplanmasında standart matematiksel formüller kullanılmış, verilerin istatistiksel analizinde, Student Newman Keul’s testi ile varyans analizi uygulanmıştır. Denemede Cu etkisine bırakılan balıklarda HSI’de kontrole göre artış, GSI ve CF’nde deneme süresi sonunda azalma saptanırken, Pb etkisine bırakılan balıklarda HSI’de kontrole göre azalma (P<0,05), GSI ve CF’nde ise istatistiksel olarak önemli bir fark saptanmamıştır (P>0,05).
