The study was conducted to observe the changes in organoleptic and bio-chemical parameters of three marine ﬁsh species of Bay of Bengal during ice storage. The ﬁsh species, viz., Bombay duck (Harpadon nehereus), silver jewﬁsh (Johnius argentatus) and ribbon ﬁsh (Trichiurus haumela) were collected from the landing center of Cox’s Bazar and frozen transported to Mymensingh city. After arrival in Mymensingh, the ﬁsh samples were stored in ice for about 9 days by applying fresh ﬂakes of ice to the ﬁshes at regular interval. During the storage period, required amount of ﬁsh samples were taken out from the ice box at two-day interval to collect data on changes in
organoleptic and biochemical parameters (e.g., analysis of proximate composition, TVB-N and pH). During ice storage, the overall organoleptic qualities of all ﬁsh samples were in acceptable condition up to 9 days. The ﬁsh samples stored in ice exhibited excellent quality on the basis of physical characteristics until 3rd day of storage. Biochemical analyses revealed that the percent moisture content of Bombay duck, silver jewﬁsh and ribbon ﬁsh increased with the lapse of storage period whereas the percent protein content decreased With the progress in storage period. Lipid content also decreased gradually in the same samples but the percent ash content of the samples changed very little. The values for total volatile base nitrogen (TVB-N) of the three ﬁsh samples increased slightly during the storage period. The pH value of the
ﬁsh samples also increased throughout the storage. So, the present study conclude that the organoleptic characteristics and biochemical parameters of above mentioned ﬁsh changes during ice storage of 9 days but found acceptable for human consumption.
