    Utilisations
    In native ranges of Europe, Carcinus maenas has been fished commercially for years (Klassen, 2007). In addition, this species has been recommended as an indicator species for the monitoring of heavy metal contamination because heavy metal pollution has been associated with respiratory failure in crabs (Klassen & Locke, 2007). While in its native range, this species is considered an important scavenger, especially of commercial fishery discards (Klassen & Locke, 2007).
    Cette espèce figure sur la liste de l’UICN des 100 espèces parmi les plus envahissantes au monde
