Cold stress due to overwintering is considered a major issue limiting the development of red tilapia ( Oreochromis spp.) industry. This study was first systematically investigate effects cold on skin color, immuno‐antioxidant function, muscle compositions, and intestinal microbiota during overwintering. Fish (initial weight: 72.71 ± 1.32 g) were divided into group (cold) control group. In group, water temperature (WT) maintained at 20°C, which consistent with WT indoors or greenhouse in local area. decreased from 20°C 8°C by 2°C per day experiment. At end experiment, we found that L ∗ value fish ventral lower than p < 0.05). The superoxide dismutase (SOD), malondialdehyde (MDA), glutathione (GSH), catalase (CAT), total antioxidant capacity (T‐AOC) activities higher, but complement 3 (C3) 4 (C4) liver those For gill tissue, SOD, MDA, GSH C3 activity amino acid (TAA) content higher 16 s rRNA analysis showed microbial abundance alpha diversity Component revealed significantly relative Cetobacterium spp. findings this will provide valuable understanding overwintering, contribute facilitating breeding new cold‐resistant varieties future.
