Estimation of the nitrogen-phosphorus load caused by rainbow trout (Oncorhynchus mykiss Walbaum, 1792) cage-culture farms in Kesikköprü Dam Lake: a comparison of pelleted and extruded feed

Öz:

BU araştırma, Kesikköprü Baraj Gölü’nde Nisan-Temmuz 2006 tarihleri arasında, yaklaşık 20’şer ton/yıl kapasiteli, pelet ve ekstrude yem kullanılarak gökkuşağı alabalığı (Oncorhynchus mykiss Walbaum,1792) yetiştiriciliği yapan iki farklı kafes işletmesinden göle bırakılan azot ve fosfor yükünün tahmini amacıyla yürütülmüştür. Kesikköprü Baraj Gölü’nde pelet yemin kullanıldığı kafeslerde, 1 ton balık üretiminde azot yükü 56,00 ve 62,92 kg, fosfor yükü 10,66 ve 12,17 kg; ekstrude yemin kullanıldığı kafeslerde ise 1 ton balık üretiminde azot yükü 33,47 ve 25,97 kg, fosfor yükü 7,32 ve 7,96 kg olarak tahmin edilmiştir. Araştırmada elde edilen kantitatif bulgular ışığında, kafeslerde gökkuşağı alabalığı yetiştiriciliğinin yapıldığı iç sularda yetiştiriciliğin sürdürülebilirliğini sağlamak ve yetiştiriciliğin ötrofikasyona etkisini minimuma indirmek açısından ekstrude yem kullanımının uygun olacağı belirlenmiştir.

This research was conducted in order to estimate the nitrogen and phosphorus loads released into Kesikköprü Dam Lake between April and July 2006 from 2 different rainbow trout (Oncorhynchus mykiss Walbaum, 1792) cage farms. Both farms had a capacity of about 20 t year–1, and used pelleted and extruded feed. In Kesikköprü Dam Lake the nitrogen load was estimated to be between 56.00 and 62.92 kg t–1 of fish produced, and the phosphorus load was estimated to be between 10.66 and 12.17 kg t–1 of fish produced in cages in which pelleted feed was used, In cages in which extruded feed was used, the nitrogen load was estimated to be between 33.47 and 25.97 kg t–1 of fish produced, and the phosphorus load was estimated to be between 7.32 and 7.96 kg t–1 of fish produced. Based on the quantitative results of this study, it was concluded that for aquaculture to be sustainable in inland waters where rainbow trout is cultured, and to minimize its influence on eutrophication, it would be beneficial to use extruded feed.
