Siganus rivulatus Forsskål & Niebuhr, 1775

Two Marbled spinefoot, Siganidae , were collected on August 2018 by the fisherman Christophe Agniel, using seinche (a local fishing gear) at Pointe du They de la

Gracieuse, near the mouth of the Rhône River, in the Gulf of Fos, close to the Parc Marin de la Côte Bleue (Bouches-du-Rhône, Mediterranean Sea, France), at about 43.39°N, 4.92°E, at roughly 6 m depth, on a sandy bottom, near the shore. The fresh individuals measured approximately 30 cm TL. During the summer 2018 another fishermen, Patrick Bozonnat, also twice caught some Siganus . Based on the yellow stripes observed on the belly of the fishes, the fishermen identified them as S. rivulatus and not as S luridus (Rüppell, 1829) . Unfortunately, no picture was taken. Recorded by E. Charbonnel. Two individuals of the other congeneric lessepsian species S. luridus were recorded for the first time from the Northwestern and French Mediterranean coasts, in the same area, in 2008 ( Daniel et al., 2009). This lessepsian species is an addition to the Checklist of the marine fishes from metropolitan France ( Béarez et al., 2017). Its spread may be related to warming waters as a consequence of climate change.
