Abstract
This study was carried out to determine the effect of three trout fish farms on the water quality of Karapınar Creek between January - December 2012.During the study, measured water quality parameters varied in different ranges, water temperature 15.6 - 17.9 ˚C, pH 7-7.94, dissolved oxygen 6.04 - 9.75 mg/l, electrical conductivity 431.00 - 545.00 µs/cm, suspended solid matter 0.1 - 18.2 mg/l, chlorophyll-a 0.12 - 11.38 mg/m3, total alkalinity 280 - 510 CaCO3/l, total hardness 285 - 397.1 CaCO3/l, chemical oxygen demand 27 - 79 mg/l, nitrite nitrogen 0.001 - 0.015 mg/l, nitrate nitrogen 0.54 - 0.87 mg/l, ammonium nitrogen 0.018 - 0.033 mg/l, orthophosphate 0.002 - 0.009 mg/l, total nitrogen 0.68 - 1.07 mg/l, total phosphorus 0.016 - 0.030 mg/l, sediment total kjeldahl nitrogen 841 - 1436 mg/kg and sediment total phosphorus 95 - 145 mg/kg.In conclusion, according to the Water Pollution Control Regulation of Inland Water Resources Criteriathe creek can bewas classified as I. class (high quality water) with regard to water temperature, dissolved oxygen, chemical oxygen demand, nitrite-nitrogen, nitrate-nitrogen, ammonium-nitrogen and total phosphorus. This situation might be related tothe low capacity of trout farms and low feeding intensity. It was also determined that non-consumed feed and wastes from metabolic activities of fish did not accumulate due to the high flow rate.
Özet
Bu çalışma, Karapınar Deresi üzerinde bulunan 3 alabalık tesisinin su kalite parametreleri üzerindeki etkilerini incelemek amacıyla Ocak - Aralık 2012 tarihleri arasında gerçekleştirilmiştir.Çalışmada incelenen su kalite parametrelerinden sıcaklık 15,6 - 17,9 ˚C, pH 7 - 7,94, çözünmüş oksijen 6,04 - 9,75 mg/l, elektriksel iletkenlik 431,0 - 545,0 µs/cm, askıda katı madde 0,1 - 18,2 mg/l, klorofil-a 0,12 - 11,38 mg/m3, toplam alkalinite 280 - 510 CaCO3/l, toplam sertlik 285 - 397,1 CaCO3/l, kimyasal oksijen ihtiyacı 27 - 79 mg/l, nitrit azotu 0,001 - 0,015 mg/l, nitrat azotu 0,54 - 0,87 mg/l, amonyum azotu 0,018 - 0,033 mg/l, ortofosfat 0,002 - 0,009 mg/l, toplam azot 0,68 - 1,07 mg/l, toplam fosfor 0,016 - 0,030 mg/l, sedimentte toplam kjeldahl azotu 841 - 1436 mg/kg ve sedimentte toplam fosfor 95 - 145 mg/kg aralığında değişmiştir.Sonuç olarak, Karapınar Deresinde su kalitesi, su kirliliği kontrol yönetmeliğine (SKKY) göre sıcaklık, pH, çözünmüş oksijen, kimyasal oksijen ihtiyacı, nitrit azotu, nitrat azotu, amonyum azotu ve toplam fosfor değerleri yönünden I. sınıf olarak belirlenmiştir. Bu durumun alabalık çiftliklerinin kapasitelerinin düşük ve yemleme yoğunluğunun az olmasından kaynaklandığı düşünülmektedir. Tüketilmeyen yem ve balıkların metabolik faaliyetlerinden kaynaklanan atıkların, yüksek debi sayesinde birikim yapmadığı tespit edilmiştir.
