Abstract


We report winter predation by River Otter, Lontra canadensis, on Tautog, Tautoga onitis, a southern marine fish, at Western Arm Jeddore Harbour, Halifax County, Nova Scotia (44°46'N, 63°03'W), on 17 February 2008. We also discuss the distribution of Tautog in the western Atlantic Ocean, review Canadian records, and provide evidence that resident relict populations of this fish exist in Nova Scotia and New Brunswick.
