Abstract
Among small indigenous species (SIS) of fishes Mola (Amblypharyngodon mola) has high nutritive value. Beside traditional curry preparation it is necessary to make available this highly nutritive fish in other ready to eat forms and also adding value to this fish. Therefore, this study was carried out to prepare fish pickle with Mola (Amblypharyngodon mola) and to observe the sensory, chemical and microbiological changes of fish pickle stored at room temperature (28C to 32C). The study was conducted in the Department of Fisheries Technology Laboratory, Bangladesh Agricultural University. The results of the study showed that, the percent moisture content, protein content decreased while prepared pickle than those values obtained for fresh fish. On the other hand, lipid and ash content increased than the values found in fresh fish. While the fish pickle stored at room temperature (28C to 32C) in different packing condition, the percent moisture, protein and lipid content decreased with the progress in storage period gradually but ash content increased. At this temperature, pH value of the pickle decreased very slowly but the TVB-N value and bacterial load increased progressively throughout the storage period. So, it was concluded that, at room temperature (28C to 32C) shelf life of Mola (Amblypharyngodon mola) fish pickle was short, pickle may remain in acceptable condition until 12 days in sealed pack and 30 days in vacuum sealed pack.

Key words: Fish pickle, Mola (Amblypharyngodon mola), biochemical parameters, storage, room temperature (28C to 32C)
