Biochemical, nutritional and microbiological quality of six smoked fishes viz. Esomus danricus, Puntius sophore, Mystus bleekeri, Amblypharyngodcm mola, Notopterus notopterus and Glossogobius giuris of Manipur were analysed. Non protein nitrogen (NPN) and total volatile base nitrogen (TVBN) were 0.50 to 1.86% and 40.00 to 80.00 mg% respectively. In vitro digestibility of one sample (P. sophore) was higher than that of casein. Alpha amino nitrogen liberated in pepsin phase were 28.44 to 49.75% of total N and in trypsin phase, 53.25 to 70.37% of total N. Available lysine content was 2.17 to 4.68 g/16g of N. Total plate count of bacteria (TPC), total plate count of fungi (TFC), most probable number (MPN) of coliform, Staphylococcus aureus and faecal Streptococci counts were lOMO g-1, lOMO g-1, O-lO g"1, and lOMO g"1 respectively. But Escherichia coli and Salmonella were not detected in any of the smoked fishes studied. Aspergillus niger and Cladosporium cladosporoides were the dominant fungal flora.
