Movement behaviours of stocked and wild lake trout Salvelinus namaycush determined using acoustic telemetry.

ABSTRACT: Hatchery practices are a critical tool of fisheries management to supplement diminished fish populations and restore extirpated species. However, stocking programs that successfully restore self-sustaining populations are rare. Unintentional artificial selection and domestication of hatchery-reared fish are potential limitations to the success of stocked individuals by selecting for behaviours that are poorly suited for natural conditions. Here, we compared seasonal movement behaviours between an established population of hatchery origin (stocked) and naturally produced (wild) lake trout (Salvelinus namaycush) in Lake Champlain at a range of sizes, including immature and mature fish. Fifty-six stocked and 34 wild lake trout were implanted with acoustic transmitters, including 45 transmitte
