Abstract: The present study was conducted on small indigenous dry fish for evaluating proximate composition
viz ash, protein, total sugar, fibre, fat, phosphorus, sulfur and sodium content. Three species were used such as
Puti (
Puntius sophore),
Mola (
Amblypharyngodon mola), and
Darkina (
Esomus danricus)
. Our study showed that there was a little variation in the nutrients and mineral content of
Mola,
Puti and
Darkina fish collected from different northern region of Bangladesh.
Puti fish shows good nutrients in all districts except sodium and phosphorus in Dinajpur district. In case of
Mola fish the protein, total sugar and fiber content is slightly higher in Bogura, Rajshahi and Dinajpur districts respectively, whereas the phosphorus content is slightly higher in Dinajpur district compare with other districts. From the analysis of
Darkina fish it was found that, ash content in Dinajpur is slightly higher than other districts. The ash content of the dried fishes obtained was in the range of 14.30 to 18.65% and the highest value obtained from
Darkina (
Esomus danricus) and the lowest from
Puti (
Puntius sophore). The protein content was found in the range of 41.59 to 61.96% with the highest value in
Mola (
Amblypharyngodon mola) and the lowest in
Darkina (
Esomus danricus). There was a variation in total sugar content which is in the range of 1.61 to 2.65% where the highest value in
Mola (
Amblypharyngodon mola) and the lowest in
Puti (
Puntius sophore). Fibre content was in the range of 2.17 to 8.74% with the highest value obtained from
Puti (
Puntius sophore) and the lowest value from
Mola (
Amblypharyngodon mola). The fat content was in the range of 2.17 to 7.77% with the highest value obtained from
Puti (
Puntius sophore) and the lowest in
Mola (
Amblypharyngodon mola). It is concluded that climate change, species variation, and the feeding habit may be the major factors to uphold the nutrient content in SIS.
