ABSTRACT: Dry fish is the low cost dietary protein source in Bangladesh. Sometimes dry fishes are kept for a longer period that is the key factor of the deterioration of nutritional value of dry fishes, as they absorb moisture from the surrounding air. The general purpose of this study is to determine the proximate composition of three available marine dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala) and to investigate the changes of nutritional value of these selected dry fishes with the increasing of storing period. The result of this study shows that the mean percentage of moisture content increased at a significant level with the increasing of storing period. For 2 years storing period the moisture content is increased by 12.77%, 11.89% and 6.69% for the three dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala respectively). The result of this study also shows that the mean percentage of protein (6.35, 7.93 and 4.68), lipid (1.92, 0.67 and 1.13), and carbohydrate (1.70, 1.81 and 0.66) of three dry fishes (Harpodon nehereus, Johnius dussumieri and Lepturacanthus savala respectively) decreased greatly for 2 years storing period. The findings of this study showed that nutritional value of dry fishes deteriorate with the increasing of storage period.
