Acipenser sturio Linnaeus, 1758

A European sea sturgeon, Acipenseridae ( Fig. 2D), was captured on 4 Jun. 2018 by the fisherman Mr Pierre Nicolas, on the coastal trawler Lhassa from Concarneau with a bottom trawl. It was captured between the Glénan archipelago and the island of Groix (Bay of Biscay, France), at 47.647667°N, – 3.743767°W, at 60 m depth on bottom a mixed sand and rock seafloor. The fresh specimen measured 115 cm TL. A fin clip was collected by the fisherman and is preserved at SMC with No. BPS-4006. The specimen was released alive in very good condition. Recorded by S.P. Iglésias. A previous specimen of sturgeon, 110.5 cm TL, was captured by the same fisherman on 12 Nov. 2012 in the same area ( Iglésias, 2013). The present specimen, most evidently born in captivity, was initially released according to a reintroduction plan for this Critically Endangered and protected species ( MEDDTL, 2011). All capture information and samples were returned to the competent authorities according to the National Action Plan for the European sea sturgeon.
