The purpose of this study was to determine the microbiological quality of smoked yellow tail fish. The research included microbiological tests, bacterial gram staining of selected isolates, and bacterial biochemical tests according to Indonesia National Standard. The total microbial count (TPC) was carried out in three samples using the pour plate method with six dilution factors. Bacterial colonies with different morphologies were then inoculated on PCA media for gram staining and biochemical tests. The bacterial biochemical tests included carbohydrate fermentation test, Methyl-red Voges-Proskauer test (MR-VP), citrate test, motility test, Triple Sugar Iron Agar (TSIA) test, indole test, and catalase test. The results showed that sample A had lower number of microbial contamination compared to that of sample B and C at a dilution factor of 10<sup>-6</sup>. Gram staining was carried out for selected isolates, namely white isolates (isolate A) with a flat surface and cream colored isolates (isolate B) with slightly protruding surfaces. Isolate A was gram positive, while isolate B was gram negative. Biochemical tests showed that isolate A produced glucose (+), maltose (+), MR-VP (+) and SCA (+) tests while isolate B produced glucose (+), maltose (+), NA (+) and SCA tests. (+) so it was suspected that the bacteria in smoked fish were <em>Staphylococcus</em> and <em>Salmonella</em> groups</p&gt;}, number={3}, journal={Jurnal Pengolahan Hasil Perikanan Indonesia}, author={Haryati, Kristina}, year={2020}, month={Dec.}, pages={486-494} }
