Popis: The present study was conducted to clarify the effects of Lactobacillus salivarius (LS) ATCC 11741 and pectin (PE) on growth performance, digestive enzymes activity, gut microbiota composition, immune parameters, antioxidant defense as well as disease resistance against Aeromonas hydrophila in narrow-clawed crayfish, Postantacus leptodactylus. During 18 weeks trial feeding, 525 narrow-clawed crayfish juvenile (8.07±0.1 g) fed with seven experimental diets including control (basal diet), LS1 (1×107 CFU/g), LS2 (1×109 CFU/g), PE1 (5 g/kg), PE2 (10 g/kg), LS1PE1 (1×107 CFU/g +5 g/kg), and LS2PE2 (1×109 CFU/g +10 g/kg). After 18 weeks, growth parameters (final weight, weight gain, and specific growth rate) and feed conversion rate were significantly improved in all treatments (P
