Comprehensive evaluation of environment adaptability in wild and captive lenok (Brachymystax lenok): from the perspective of antioxidant capacity, immune response and gut microbiome

Collectively, these findings demonstrate significant differences in intestinal morphology, digestive function, and microbial community composition between wild and farmed <i>B. lenok</i>. This study provides new insights for improving post-stocking adaptability in reintroduction programs and proposes novel conservation strategies for biodiversity restoration.
