Abstract: The present study attempted to evaluate the quality of eight dried fishes (
Puntius sp.
Chanda sp.
Amblypharyngodon mola,
Oxygaster gora,
Cirrhinus reba,
Glossogobius giuris,
Channa punctatus,
Mastacembelus pancalus) which were produced employing traditional method in Chalan Beel areas by local dried fish processors and the experimental dried products were prepared through proper processing method in Department of Fisheries, University of Rajshahi, Bangladesh, from February, 2015 to July, 2015. Traditional and experimental samples were subjected to biochemical analysis on 1st, 4th and 6th month. In the storage period of traditional dried fishes, the average highest bacterial load was 7.8ï‚´10
5 cfu/g in
Mastacembelus pancalus on 6th month and lowest APC was 3.6ï‚´10
3 cfu/g) in
Channa punctatus on 4
th month whereas in experimental dried fishes the highest Aerobic Plate Count (APC) was 1.42ï‚´10
5 cfu/g in
Mastacembelus pancalus on 1
th month and the lowest APC was 5.2ï‚´10
2 in
Puntius sp. on 4
th month. From the 1
st, 4
th and 6
th month the highest average value of Total Volatile Base Nitrogen (TVB-N) was 38.08 mg/100g in
Oxygaster gora while lowest TVB-N value was 23.13 mg/100g in
Amblypharyngodon mola in traditional dried fishes whereas the highest TVB-N value was 31.77 mg/100g in
Channa punctatus and lowest TVB-N value was 17.02 mg/100g in
Chanda sp in experimental dried fishes. The lowest and highest average values of TMA in traditional dried fishes were 6.91mg/100g and 8.70 mg/100g in
Oxygaster gora and
Mastacembelus pancalus respectively whereas in experimental dried fishes the highest TMA value was 10.58 mg/100g in
Channa punctatus and lowest TMA value was 4.98mg/100g in
Puntius sp. In experimental dried fishes, no pathogenic bacteria were present but
Escherichia coli and
Klebsiella sp. were found in
Cirrhinus reba and
Oxygaster gora respectively in traditional dried fish.
