Survival and behaviour of post-smolt Atlantic salmon in coastal habitat with extreme tides

The early marine migration of 55 Atlantic salmon post-smolts tagged with acoustic transmitters was automatically monitored using 13 to 25 km long arrays of receivers deployed inside the Bay of Fundy, a coastal system on the east coast of Canada. The survival of post-smolts from groups with short- and long-term transmitters in coastal habitat up to 10 km from the river was 92 to 100%, indicating a successful transition to salt water and departure. Migration for 68 to 77% of post-smolts followed a direct route and it was rapid (transit time usually
