The effects of air packaging (AP) and modified atmosphere packaging 1 (MAP1) (50% CO₂/50% N₂), MAP2 (70% CO₂/30% N₂), and MAP3 (90% CO₂/10% N₂) on the preservation property of Golden Pompano Trachinotus ovatus stored at 0 °C were studied. Results demonstrated that MAP exhibited better preservation effects than AP. Based on sensory scores, the shelf life of fillets under AP and MAP was 10 and 16 days, and MAP2 was the best among all treatments ( P < 0.05). MAP significantly inhibited increases in total volatile basic nitrogen (TVB-N), thiobarbituric acid (TBARS), K-value, and total viable count (TVC), slowed reductions in hardness and springiness ( P < 0.05). Proteobacteria was the dominant phylum, Exiguobacterium , Vibrio and Citrobacter were the prevalent population in MAP at the end of storage. Vibrio anguillarum was the predominant taxon associated with spoilage. In summary, MAP2 demonstrates considerable potential for enhancing the shelf life of T. ovatus at 0 °C.
