Özet:

 Biofloc technology BFT has become an agenda to meet the need for protein food and ornamental aquaculture with the increasing interest in sustainable aquaculture. In this context, the current study focused on BFT for ornamental goldfish Carassius auratus, which has commercial value. The study was conducted with control and two different CN ratios 15:1 and 20:1. On the other hand, increasing the CN ratio had a positive effect on total suspended solids and total bacteria count in the culture water. The specific growth rate and weight gain were observed to be significantly higher at a high CN ratio. The feed conversion ratio was lower in the CN 20 group, indicating a more efficient feed utilization. According to the liver histological results, the vacuolization symptom is more severe in BFT groups. Considering all the results, the suitability of C. auratus cultivation in the BFT system with a CN ratio of 20 was proven according to nine different evaluation criteria. In conclusion, rearing C. auratus in BFT systems is advised due to its economic and ecological benefits.

 Biyoflok teknolojisi BFT, yalnızca protein ihtiyacını karşılamak için değil, aynı zamanda akvaryum balığı yetiştiriciliği için de gündeme gelmiştir. Bu bağlamda, mevcut çalışma ticari değere sahip bir tür olan Japon balığı Carassius auratus üzerine odaklanmıştır. Kontrol grubu ve iki farklı CN oranı 15:1 ve 20:1 ile gerçekleştirilen çalışmada, BFT gruplarında azot döngüsü hızlı bir şekilde gerçekleşmiştir. Diğer yandan, CN oranının artırılması, kültür suyunda toplam askıda katı madde ve toplam bakteri sayısı üzerinde olumlu bir etki göstermiştir. Büyüme performansı açısından, yüksek CN oranında spesifik büyüme hızı ve ağırlık artışı önemli ölçüde daha yüksek gözlemlenmiştir. Yem değerlendirme oranı ise CN 20 grubu için daha düşük sonuçlar göstermiştir. Karaciğer histolojik sonuçlarına göre, vakuolizasyon semptomunun BFT gruplarında daha şiddetli olduğu tespit edilmiştir. Tüm sonuçlar göz önünde bulundurulduğunda, 20 CN oranına sahip BFT sisteminde C. auratus yetiştiriciliğinin uygunluğu dokuz farklı değerlendirme kriterine göre kanıtlanmıştır. Sonuç olarak, C. auratusun BFT sistemlerinde yetiştirilmesi hem ekonomik hem de ekolojik açıdan önerilmektedir.
