This study was aimed at determining the shelf-life of gutted croaker (Micropogonias furnieri) and stocked at 0°C using physical-chemical and sensory analyses. On the 14th day of storage, the pH of the muscle tissue reached the accepted limit for consumption (6.4). The levels of TVB were kept within the stipulated values for consumption (30mgN 100g-1) until the 21st day. In 28 days of storage at 0°C, the histamine level did not excess the acceptable level of 10mg 100g-1 of meat. The quantitative descriptive analysis method employed 9 attributes to describe the croaker. The study found that aroma and taste of sea fish, aroma and taste of marshy smell, bitterness, and the color of the meet were the most important aspects differentiating samples after 0, 4, 7, 10, 14 days of stocking at 0°C. According to the obtained results, and based on the standards of national and international legislation, it was confirmed that the commercial shelf-life of gutted croaker (Micropogonias furnieri) stored at 0°C is 14 days.
