In this study frozen-thawed rainbow trout (Onchorhynchus mykiss) and seabass (Dicentrarchus labrax) fillets were used for preparing of dry fermented fish sausages. The total mesophilic aerob bacteria (TMAB), total psychrophilic aerob bacteria (TPAB), yeast–mould (YM), lactic acid bacteria (LB), Enterobactericeae (EB), Staphylococcus aureus (SA) changes of these dry fermented sausages were examined in the refrigerated storage at 6-8˚C. At the end of the storage period of 90 days, the results of the TMAB, TPAB, YM, LB, EB and SA counts of dry fermented seabass sausages were determined as 6.25, 7.01, 3.61, 5.31, <1.0 ve <1.0 log cfu/g, while, TMAB, TPAB, YM, LB, EB and SA counts of dry fermented trout sausages were found as 6.57, 7.20, 4.44, 5.14, <1.0 ve <1.0 log cfu/g, respectively. In this study both fermented fish sausages were determined as too much dried and exceeded the microbiological limit of TMAB at the end of the storage period of 90 days in the refrigerator. However, fermented seabass sausage reached the maximum level of YM count on the 10th day of storage, whereas fermented trout sausage reached this level on the 30th day of storage. Therefore, it is suggested that they should be packaged in vacuum packaging because of preventing too much drying and the growth of undesirable moulds. Additionally, the identification of microorganisms in fermented fish sausages would also be advised to determine desirable and undesirable microorganisms. Dry fermented fish sausage would be an alternative product to traditional dry fermented meat sausage in Turkey because of the health benefits of fish.
