The aim of our study was to survey the geosmin (GSM) and 2-methylisoborneol (MIB) concentrations of the sediment and that of common carp (Cyprinus carpio) fl esh in three different Hungarian fi sh farms (clayey, marshy, and sodic ponds). Results showed that the concentrations of off-fl avour compounds of the sediment and fi sh fi llets were related to the natural environment. The GSM concentration of bottom soil samples was higher, than MIB in each fi sh farm. Both off-fl avour compounds were the highest in the marshy fi sh pond and the lowest in the sodic pond. In case of fi sh fl esh, signifi cant differences were found between the farms in GSM level and fat content. In the fi sh fl esh the same tendency was found as in the sediments, but surprisingly, MIB concentration was higher in the fi llets, referring to accumulation.
