DOI : 10.4194/AFS116 - The present study was conducted to investigate the chemical, microbial, sensory, and physical characteristics and to determine the storage time of two-year-old farmed A. persicus in ice. In the present study, 20 numbers with an average weight and length of 3.50 kg and 70 cm, were kept in CSW (Chiled sea water) tanks, and their microbial, chemical, physical and sensory properties were investigated for 12 days. Microbial agents including the total bacteria counts and Staphylococcus and Enterobacteriacea bacteria, physical such as pH and chemical such as peroxide value, thiobarbituric acid (TBA), free fatty acids, and total volatile nitrogen bases increased significantly during storage (p<0.05). Contamination to coliform, Escherichia coli, and Pseudomonas bacteria was not observed during storage. But sensory characteristics including skin general appearance, texture, odor, the appearance of gills, eyes, and general acceptance decreased significantly during storage (p<0.05). According to the obtained results, the chemical, microbial, sensory, and physical properties were of good quality during the 8 days of keeping two-year-old farmed A. persicus in ice. Therefore, the shelf life of this fish was determined to be 8 days. Keywords : Cold storage Ice storage Farmed A. persicus Quality Shelf life
