Evidence of High Levels of Gene Flow in a Widely Distributed Catadromous Species: The Thin-Lippedgrey Mullet
The thin-lipped grey mullet Chelon ramada (Risso, 1827) is a catadromous species that is distributed along the Northeast Atlantic, from the Norwegian coastline down to Mauritania, on the African coast (20–60◦ N, 18◦ E–42º W), and displays diverse patterns of habitat use and migratory behaviors.
