Abstract In the present study, we aimed to evaluate the single or conjoint effects of Lactococcus lactis (L. lactis) L19 and Enterococcus faecalis (E. faecalis) W24 isolated from the intestine of Channa argus (C. argus) on digestive enzyme activity, antioxidant capacity, intestinal microbiota and morphology of C. argus (initial weight, 9.50 ± 0.03 g). The fish were fed for 56 days with a basal diet (CK) or diets supplemented with 1.0 × 108 CFU/g of L. lactis (L19), E. faecalis (W24), L. lactis + E. faecalis (L + W). Results indicated that these three lactic acid bacteria (LAB) supplementary diets especially the L19 produced significant improvement in the digestive enzyme activity (protease, amylase and lipase) in liver, stomach and intestine compared with control (P
