BACKGROUND: Changes in the biogenic amine content of tilapia ( Oreochromis mossambicus ) with time during iced and ambient temperature (28 °C) storage were quantified by high‐performance liquid chromatography in a gradient elution system using acetonitrile and water as solvents. RESULTS: The levels of amines in tilapia were significantly low even after a long storage period (18 h under ambient temperature storage and 15 days under iced storage). All amines except spermidine and spermine increased with time during both iced and ambient temperature storage. Spermidine and spermine showed a decrease with increasing storage time. CONCLUSION: Being euryhaline (tolerant of a wide range of salinity) in nature, tilapia shows significantly low quantities of biogenic amines even after a long period of ambient temperature or iced storage, unlike most other marine fish.
