First records of the blue runner Caranx crysos (Perciformes: Carangidae) in Newfoundland waters.

From August to September 2013, c. 21 specimens of the blue runner Caranx crysos were caught by commercial fishermen in two locations off the south coast of Newfoundland, Canada. These samples represent the first records of C. crysos in Newfoundland waters, and a potential northward range expansion of this species in the north-western Atlantic Ocean. They also illustrate the importance of fisher-derived sampling that spans times and locations outside of the limited range targeted by scientific surveys in this region.
