Changes in biochemical properties of freshwater prawn stored with two ice conditions Without Direct Contact with Ice (DCI) and Without Direct Contact with Ice (WCI) for day 0, 2, 4, 6, 8 and 10 were investigated. Proximate composition defined in terms of moisture increased for the DCI as storage days increases but relatively constant with treatments with WCI. Values of TVB-N (mgN/100g) in prawn stored with DCI had inverse relationship with storage days but increased with storage days in the WCI. Changes in the values of ash and crude protein were relatively constant as the storage days increased in both treatments. Ice treatments recorded little changes in between storage days for fats. Values of NPN mgN/100g decreased with days of storage with DCI but increased as the storage increased with WCI. These results obtained in this study showed that ice storage may have contrasting values and importance on the biochemical properties of the freshwater prawn.
