Groupers (Plectropomus maculatus) were harvested from holding tanks and stored in ice until assessment rated them unacceptable. Groupers were also subjected to periods (2-12 h) of storage at tropical ambient (29-31 degreesC) immediately after harvest but prior to cooling in ice. The storage life of grouper stored continuously in ice was 18 days. A 2-h delay before cooling in ice approximately halves the storage life and for every further hour of malstorage the shelf-life was further reduced by approximately 1 day. The total volatile basic nitrogen (TVBN) and hypoxanthine contents were found to be good indicators of freshness in groupers, which were only acceptable with contents < 31 mg N 100 per g and <2.0 mu moles g(-1), respectively and all unacceptable at > 37 mg N 100 per g and 2.3 mu moles g(-1) respectively. TMA-N was found not be a reliable indicator of freshness.
