Lobotes surinamensis (Bloch, 1790)

A Tripletail, Lobotidae ( Fig. 5F ), was collected on 15 Oct. 2018 by the fishing master Mr Raymond Millet on the fishing boat Jeannot from La Rochelle. It was collected between Les Sables d’Olonne and Ré Island (off Vendée and Charente-Maritime, France, Bay of Biscay), at 46.3228°N, – 1.6580°W, at 12 m depth, with a drift net. The specimen, an adult female, measured 455 mm TL, 375 mm SL, 125 mm HL and weighed 2.3 kg. The stomach was empty and the ovaries weighed 7.22 g. The meristic counts are: D: XII+15; A: III+11; P: 16; V: I+5; C: 18; gillrakers on first arch: 5+1+13. The specimen was preserved stuffed, by the ichthyo-taxidermist Bernard Bourles, with the collection No. MNHN-IC 2020-0096. The otoliths were preserved a well as a tissue sample under No. BPS-4255. Recorded by R. Causse and L. Lamour. This specimen represents the third record for the Bay of Biscay. The two former specimens, 440 and 383 mm TL, were collected on 21 Oct. 2010 and 4 Nov. 2013, off Biscarrosse (Landes, France) and close to Govihan Island (Golfe du Morbihan, France), respectively ( Quéro et al., 2011a; Iglésias, 2011, 2014; De Casamajor and Morandeau, 2013). Consequently this species can now be considered established in the Bay of Biscay. The new record for this species in the Bay of Biscay represents a northern range expansion and it may be related to warming waters as a consequence of climate change.
