The current study was designed to evaluate genotoxic and toxicopathological effct of afltoxin B1 (AFB1 ) in fresh water fish also known as Grass carp (Ctenopharyngodon idella). For the in vitro production of AFB1 , Aspergillus flvus spores were grown on potato dextrose agar (PDA) and then rice was used as a substrate. The quantity of AFB1 was found 50ppb/g of rice using high performance liquid chromatography (HPLC) technique. A total of n=150 Grass carp (42±5 g) were divided into 5 groups (A, B, C, D, E). Group A (kept as a control), while groups B, C, D and E were exposed to 25 ppb, 50 ppb, 75 ppb and 100 ppb AFB1 per kg of diet, respectively, for 49 days. The average weight gain (WG) and specific growth rate (SGR) of fish was significantly higher in group A (WG-15.35 g and SGR-0.63%) compared to group E (WG-6.55 g and SGR-0.28%). The Feed Conversion Ratio (FCR) was significantly (P
Bu çalışma, afltoksin B1 ’in (AFB1 ) ot sazanı (Ctenopharyngodon idella) olarak da bilinen tatlı su balıklarında genotoksik ve toksikopatolojik etkilerini değerlendirmek amacıyla planlandı. AFB1 ’in in vitro üretimi için, Aspergillus flvus sporları patates dekstroz agar (PDA) üzerinde büyütüldü ve daha sonra substrat olarak pirinç kullanıldı. Yüksek performanslı likit kromatografi (HPLC) tekniği kullanılarak yapılan analizlerde, pirinçteki AFB1 miktarı 50 ppb/g bulundu. Toplam 150 adet Ot sazanı (42±5 g) 5 gruba (A, B, C, D, E) ayrıldı. A (kontrol), B, C, D ve E grupları 49 gün boyunca sırasıyla kg başına 25 ppb, 50 ppb, 75 ppb ve 100 ppb AFB1’e maruz bırakıldılar. Balıkların ortalama ağırlık artışı (WG) ve spesifik büyüme hızı (SGR), A grubunda (WG-15.35 g ve SGR-0.63), E grubuna kıyasla (WG-6.55 g ve SGR-% 0.28) anlamlı olarak daha yüksekti. Yemden yararlanma oranı (FCR), kontrol grubu ile D ve E grupları arasında anlamlı derecede farklıydı (P
