Biofilms are structures formed by bacteria in the presence of convenient media. Bacteria protect themselves from chemicals such as ozone, heat, light and chlorine with biofilm structure. Fish is an important food item and it is an environment where bacteria can easily reproduce. Therefore, it is also appropriate for biofilm formation. Biofilm formation in fish and fish stalls is a threat to human health. In this study, bacteria that can grow on fish and fish stalls and their ability to form biofilms and the effect of natural products (rock salt, lemon juice, vinegar) were investigated. In the study, 47 bacterial isolates were obtained from fish and fish stalls and their molecular identifications were made. The biofilm forming abilities of the identified bacteria were determined by qualitative and quantitative analyzes. As a result of the analysis, it was determined that 36 bacterial species formed biofilm. It has been observed that vinegar and lemon juice are effective. However, rock salt was not found to be effective against biofilm forming bacteria.
