Fish play an important role in the Bangladeshi diet, constituting the main and often irreplaceable animal-source food in poor rural households. Study on the biochemical, mineral-compositions and bacteriology of three different freshly-caught fishes were conducted using standard procedures. The fishes are Channa striatus (shol), Channa punctatus (taki) and Mystus tengra (tengra). The results revealed the mean moisture contents were 77.03%, 78.05% and 74.27%; protein contents were 19.52%, 16.89% and 16.96%; fat contents were1.93%, 2.50% and 6.04%; ash contents were 1.44%, 1.36 and 2.67% respectively for C. striatus, C. punctatus and M. tengra. Chemical-parameters and Total bacterial count were in acceptable limits. Minerals included calcium (11.2-22.02 mg/g) and magnesium (9.4-10.4 mg/g) while iron, zinc, copper and manganese were present in trace amounts. The data has proved with strong evidence that the fishes undertaken for the present study are rich in most of the nutrients essential for proper health maintenance of humans.
