The langoustine (Nephrops norvegicus) is not a small langouste (crawfish), contrary to what its name might suggest in French. It belongs to an infraorder of the Nephropinae family which also includes lobster and crayfish, but not crawfish. In France, langoustines are mainly fished by bottom trawls by a fleet of about eighty boats making fourteen-day trips from the ports of southern Brittany (Guilvinec, Douarnenez, Lorient). The mesh of their nets allows them to reorient themselves towards fish when the langoustine catches decrease. Most of the langoustines landed in France and sold in the fish markets, such as the one in Trouville-sur-Mer (photo), measure between 4.3 and 5.9 inches (11 and 15 cm).
