Abstract

Water temperature, dissolved oxygen, pH, secchi depth, nitrogen and phosphorus fractions were determined at three stations cage station, distance 15m and 60m from cage station depending on months and depth to investigate the effect of cage fish farm of 55 ton capacity in Kesikköprü Dam Lake. During the study period, decreases in dissolved oxygen and transparency values were not have a negative effect on fish culture. Water temperature and pH values were not shown clear variations according to stations. Differences in nitrite-nitrogen and nitrate-nitrogen concentrations belonging to stations were not found to be statistically significant. A significant increase in concentrations of total phosphorus and ammonia-nitrogen was detected within the cages and the bottom. According to the parameters of total phosphorus and ammonia-nitrogen the cage fish farm had localized impacts on the lake environment at its present production level.

Özet

Kesikköprü Baraj Gölü'nde 55 ton kapasiteli kafes i ş letmesinin göle etkisini tespit etmek için, üç istasyonda kafes istasyonu, kafesten 15m ve 60m uzakta olan aylara ve derinli ğe göre su s ı cakl ığı , çözünmüş oksijen, pH, ışı k geçirgenli ğ i, azot ve fosfor fraksiyonlar ı belirlenmi ştir. Çal ışma periyodunca çözünmü ş oksijen ve ışı k geçirgenliğ i değerlerindeki dü ş üş ler bal ı k yetiştiriciliğ ini olumsuz yönde etkilememi ştir. Su s ı cakl ığı ve pH değerleri istasyonlara göre belirgin bir farkl ı l ı k göstermemiştir. İ stasyonlara göre nitrit-azotu ve nitrat-azotu konsantrasyonlar ı aras ı ndaki farkl ı l ı klar istatistiki aç ı dan önemli bulunmamışt ı r. Kafeslerde ve dip sular ı nda toplam fosfor ve amonyak—azotu konsantrasyonları nda ise önemli art ış lar tespit edildiğ inden, bu parametreler aç ı s ı ndan kafes işletmesinin ş u anki üretim seviyesinde göl ortam ı üzerine lokalize etkisi oldu ğ u belirlenmiştir.
