All 780 prawns (0.19 ± 0.01 g) were randomly distributed into one control group with 1/3 water changed daily (no carbon source addition) and three biofloc groups with glucose, sucrose and molasses addition (limited-exchanged water), respectively. The experiment was set on completely randomized design with three replications. Problems with aerators can affect the suspension of biofloc, thus leading to the accumulation of biofloc biomass, the creation of anoxic zones and the dramatic reduction in dissolved oxygen. The biofloc volume dynamics in the water showed that carbon addition significantly promoted the biofloc formation in all biofloc groups (P < .05), meanwhile, during the 45-day rearing period, biofloc improved water quality by consuming the element N accumulated in the water, then leading to the decrease in the concentration of TAN and NO2−-N. A proven fish stocking combination that provides both food and good sport-fishing is bluegill, channel catfish, largemouth bass and often fathead minnows initially as a forage fish. The paper ends with a few managerial implications. to increase the growth and survival rate of fishes and promote its propagation 5).
