A Comparison of Lipids and Fatty Acids of the Ocean Quahaug, Arctica islandica , from Nova Scotia and New Brunswick
Lots of ocean quahaugs, Arctica islandica, respectively from Nova Scotia and New Brunswick, were compared to see if fatty acid compositions might reflect local food sources and thus explain alleged flavor problems. Lipid contents increased from May to July, but detailed fatty acid comparisons includ...
