Acipenser gueldenstaedtii Brandt & Ratzeburg, 1833 View in CoL
A Danube sturgeon or Osetr, Acipenseridae ( Fig. 2E View Figure 2 ), or a hybrid A. gueldenstaedtii / A. baerii Brandt, 1869 , was observed by a beachgoer on 9 Jun. 2018, washed up on La Gachère beach (Bretignolles-sur-Mer, Vendée, Bay of Biscay, France), at about 46.60°N, – 1.85°W. The specimen was about 60 cm TL. The Danube sturgeon is a fresh and brackish water fish native to the Black sea area, from where it has been introduced in various European countries. In France the species is farmed for caviar or for ornamental purposes. It is exceptionally found in French rivers where it is considered an escapee from farms. One possible explanation for the present record could be the escape of a farmed fish carried dead or alive out to sea by a neighbouring river. Identification of the specimen (by INRAE and IGB experts; Marie-Laure Acolas, pers. comm.) and diagnostic distinction from the native A. sturio were mostly based on the shape of the body and scutes. Recorded by P. Cosquer.
