Evaluating the water quality changes and formation of Bio-Floc in a zero-exchange water of common carp (Cyprinus carpio) culture system using different ratios of carbon to nitrogen (C:N)

The Bio-Floc has more efficacies compared to fixed Bio-film for removing the nitrogen compounds in water recirculating fish culture system.In Kitchen Knife this trial, a completely randomized experimental design was run to evaluate the roles of three different ratios of carbon to nitrogen (C:N) including 10 (treatment 10 = T10), 15 (T15) and 20 (T2
