Caranx crysos (Mitchill, 1815)

A Blue runner, Carangidae ( Fig. 5A ), was collected on 3 Nov. 2018 by a sport fisherman, accompanied by the fishing guide Arnaud Delaloche, with a line on the boat Squid off Cap Antifer, Étretat (Fécamp, Seine-Maritime, English Channel, France), at 49.687°N, 0.158°E, over a sand bottom with large rocks at 15-20 m depth. The specimen measured 58 cm TL and weighed about 2 kg ( Delaloche, 2018; Delcroix et al., 2019). Recorded by Y. Cordier. The species is uncommon in the Bay of Biscay, with only seven historical records since its first record in 1902 ( Fabre-Domergue, 1902; Quéro et al., 1994, 2001, 2005, 2007a; De Casamajor and Morandeau, 2013). Two specimens, 29 and 37 cm TL, were also recorded for the first time in the UK in 1992 in Portland Harbour, Dorset (English Channel) and in 1993 in Saint Ives Bay, Cornwall ( Swaby et al., 1996). This new species record for the English Channel may be related to warming waters as a consequence of climate change.
