Complement component 3 (C3) and complement component 4 (C4) in Chelon ramada fed a basal diet containing varying levels of rosemary oil and/or Zymogen Forte for a 75-day rearing trial using brackish groundwater. Data are presented as mean ± SEM of 3 replicates, where (T1) = fish fed BD without RO or ZF “control”; (T2) = fish fed the BD containing 0.5 g of RO kg− 1; (T3) = fish fed BD containing 0.5 g of RO and 1 g of ZF kg− 1; (T4) = fish fed BD containing 1.0 g of RO kg− 1; and (T5) = fish fed BD containing 1 g of RO and 1 g of ZF kg− 1; BD = basal diet, RO = rosemary oil; ZF = Zymogen Forte
