[Life cycle of Leranthropus kroyeri Van Beneden 1851, hematophagous branchial copepod of the sea bass Dicentrarchus labrax (Linné, 1758) in wild and experimental populations].

The life cycle of Lernanthropus kroyeri Van Beneden, 1851, copepod (Siphonostomatoida) parasite of Dicentrarchus labrax is described. The cycle comprises two nauplii, one infective copepodid, four fixed copepodids and one preadult. All the attached stages are caracterised by the lack of the frontal filament. This is the first description of a life cycle lacking a chalimus for Siphonostomatoida Copepods parasitic on fish.
