Quality deterioration of fish as the result of disintegration of proteins, even under chill storage, yields peptides and amino acids, which make the quality susceptible to further degradation as the result of bacterial conversion of these amino acids into hazardous biogenic amines (BAs). In this study, six biogenic amines (putrescine, cadaverine, spermidine, spermine, histamine and tyramine) in 16 days ice stored common carp (Cyprinus carpio) were evaluated at 5 intervals (0, 4, 8, 12 and 16 days). Higher levels of putrescine and cadaverine were detected at all intervals, indicating they can be good markers to determine the carp quality. Spermidine and spermine levels fluctuated during the storage and the levels of dangerous histamine and tyramine were too low to raise any concern.
