Non-Specific Immunity Associated Gut Microbiome in under Different Rearing Strategies.

To understand the intestinal microbial diversity and community structure of bighead carp () under different feeding strategies, 39 fish from three groups (A: 9 fish, natural live food only; B: 15 fish, natural live food + fish formulated feeds; C: 15 fish, natural live food + fish formulated feed + ) were obtained for the high throughput 16S rRNA gene sequencing. We first examined five non-specific immunity indications of the carp-lysozyme (LZM), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GSH-PX), and superoxide dismutase (SOD). Interestingly, the composition of gut microbiota and related non-specific immune indices were affected by the feeding treatment of the bighead carp.
