Abstract

In this study, LC50 values of three different sized (1, 5 and 10 g) rainbow trout (Oncorhynchus mykiss) fry and fingerlings at 13°C water temperature and pH 7.0 level were determined. Additionally, the relationship between the size of fish and 24, 48, 72 and 96 hour LC values was elucidated. Ninety six hour LC values for Total Ammonia Nitrogen (TAN) in 1, 5 and 10 g juveniles were found to be 10.57 mg/L, 3.39 mg/L and 2.50 mg/L, respectively. Safe upper TAN limits for each of these weight groups were calculated as 1.05 mg/L, 0.33 mg/L and 0.25 mg/L, respectively. Results of the study showed that ammonia LC50 value decreases with increasing fish weight

Özet

Bu çalışmada, üç farklı büyüklükte (1, 5 ve 10 g) gökkuşağı alabalığı (Oncorhynchus mykiss) yavrularının, 13°C su sıcaklığında ve pH 7.0 seviyesinde, amonyak LC50 değerleri tespit edilmiştir. Ayrıca balık büyüklüğü ile türün 24, 48, 72 ve 96 saatlik amonyak LC50 değerleri arasındaki ilişki belirlenmiştir. Toplam Amonyak Nitrojeni (TAN) için 96 saatlik LC50 değerleri 1, 5 ve 10 g balık yavrularında, sırasıyla 10.57 mg/L, 3.39 mg/L ve 2.50 mg/L olarak tespit edilmiştir. Her ağırlık grubu için, güvenli üst TAN seviyesi sırasıyla 1.05 mg/L, 0.33 mg/L ve 0.25 mg/L olarak hesaplanmıştır. Çalışma sonuçları balık ağırlığının artmasıyla amonyak LC50 değerinin azaldığını göstermiştir
