	abstract = {Many marine invertebrate fisheries are vulnerable to overexploitation and require conservation measures to ensure their sustainability. In recent years, landings of waved whelk <em>Buccinum undatum</em> (Linnaeus, 1758) have fallen considerably along the coasts of the St. Lawrence (Canada), dropping by up to 76\% in some fishing areas. Local overfishing may be explained, in part, by the species{\textquoteright} oviparous reproduction, which limits larval dispersion and population interactions. Using a two year long-term acoustic telemetry study, we tracked 20 individuals to assess their general movement behaviour and potential to disperse within an area. Tagged individuals displayed considerable daily movements (from a mean of 2 to 16 m/h), with no sensible differences between day and night. Both speed and habitat usage potential (HUP) varied among seasons, most likely due to the species{\textquoteright} reproductive cycle: HUP was significantly larger during the breeding season of May (4570 m2) and June (2779 m2) than in the preceding winter months (1046 m2). Although some individuals moved over a considerable depth range, we did not observe seasonality over the bathymetric gradient of the area. Overall, the species{\textquoteright} restricted HUP limits individual dispersal, resulting in very poor connection between neighbouring populations and making <em>B. undatum</em> vulnerable to local overfishing.},
