Abstract

Bu çalışmada, Karaova Baraj Gölü'nde (Kırşehir) faaliyet gösteren 274 ton kapasiteli gökkuşağı alabalığı (Oncorhynchus mykiss Walbaum,1792) kafes işletmesinin lokal çevresel durumunu (etkisini) değerlendirmek için MOM (Modelling-Ongrowing fish farms- Monitoring) B-araştırma tipi kullanılmıştır. Bu amaçla, işletme tabanından Ekim (2015) ve Nisan (2016) aylarında alınan sediment örnekleri; - biyolojik (makrofauna varlığı: Grup 1), kimyasal (pH ve redoks potansiyeli: Grup 2) ve duyusal (gaz çıkışı, renk, koku, kıvam, depozit kalınlığı: Grup 3) - olmak üzere üç grup parametreye göre değerlendirilmiştir. Ayrıca kafeslerde taşıma yoğunluğu, oksijeni baz alan farklı iki modelle tahmin edilmiştir. Kafes işletmesine ait sediment örneklerinde makrofaunaya rastlanılmamış ve sedimetin durumu biyolojik parametre açısından "kabul edilemez" şeklinde değerlendirilmiştir. Kafes işletmesinin lokal çevresel durumu kimyasal parametrelere göre "geçiş bölgesi" olarak saptanmış, duyusal parametreler açısından ise "kısmen kabul edilebilir" olarak belirlenmiştir. Sedimente ilişkin bulgular, işletmenin uzun dönemde bentik çevre üzerindeki olası negatif etkilerinin artacağına işaret etmektedir. Kafeslerde Ekim (2015) ve Nisan (2016) aylarına ilişkin taşıma yoğunluğu değerleri sırasıyla; Beveridge (1984) Modeli'ne göre 0,64 kg/m3 ve 3,71 kg/m3, Tookwinas vd. (2004) Model'ine göre ise 10,91 kg/m3 ve 72,47 kg/m3 olarak tahmin edilmiştir. Bulgular doğrultusunda, oksijeni baz alan modelleri dikkate alarak yetiştiricilik faaliyetini yönlendirmek olası gözükmemektedir. Ancak sedimente ilişkin uygulanması hızlı ve kolay çevresel kalite parametrelerinin, içsularda kurulu farklı kapasiteli kafes işletmelerinin yönetiminde ve lokal çevresel etkilerinin izlenmesinde etkin bir şekilde kullanılabileceği düşünülmektedir.

Abstract

In this study, local environmental condition (impact) of rainbow trout (Oncorhynchus mykiss Walbaum,1792) cage farm with nearly 274 tons of total production capacity using the B-investigation of the MOM (Modelling-Ongrowing fish farms- Monitoring) system in Karaova Dam Lake (Kırsehir) was determined.  For this purpose, sediment samples, which were taken from cage bottom in October (2015) and April (2016), were evaluated based on three groups of parameters -biological (macrofauna presence: Group 1), chemical (pH and redox potential: Group 2) and sensory (outgassing, colour, odour, consistency, thickness of deposits : Group 3). Moreover holding capacity of the cages was estimated using two different oxygen-based models. Benthic macrofauna were not found in all sediment samples for cage farm. The result suggested that benthic environment of the cage farm is an "unacceptable" condition. The sediment conditions according to the chemical parameters were detemined as "transition area". According to sensory parameters, the local environmental condition of cage farm was evaluated as "partially acceptable". Therefore, it is concluded that the possible negative effects of the cage culture activities on the benthic environment will increase over the long-term because of the results of environmental quality parameters of sediment. Holding capacity in the cage farm was assessed as 0.64 kg m-3 in October (2015) and 3.71 kg m-3 in April (2016) according to Beveridge (1984) Model. In addition, using Tookwinas et al. Model  (2004), holding capacity was found as 10.91 kg m-3 and 72.47 kg m-3 in October (2015) and April (2016), respectively. As a result, oxygen-based models did not indicate appropriate results for the orientation of cage culture activities. However, the fast and easily applicable parameters, proposed in the scope of present research, are thought to be used effectively in management of cage farms with different capacities and monitoring of the environmental impacts of fish farming in inland waters.
