Abstract
The oil sands industry is rapidly expanding surface mining and bitumen extraction operations near the Athabasca River in northeastern Alberta, Canada. There are anecdotal comments that the fish from the Athabasca River have an off-taste, implying that the oil sands operations are the cause. This study was done to determine if the taste of wild fishes caught near the Athabasca oil sands was less preferred than the taste of fishes collected from two other river basins in Alberta. In blinded experiments, consumer sensory panels, of 40 to 44 participants, tasted steamed samples of each of three fish species (walleye (Sander vitreus), northern pike (Esox lucius), and lake whitefish (Coregonus clupeaformis)) from three different sources in Alberta (the Athabasca River, Buck Lake, and McGregor Lake). Data analyses showed that there was no evidence from the consumer preference rankings that the taste of the fish from the Athabasca River was preferred less than the taste of fish from two other water bodies in Alberta.
