ow nloaded from ing the impact of cod farming for wild cod and endangered salmon populations. e ICES Journal of Marine Science, 63: 1364e1371. Sea cage trials of Atlantic cod farming have begun in the Bay of Fundy region. We fitted inshore wild cod (n 10) captured in the Quoddy region with sonic tags during the late summer of 2004 to provide data on their temporal and spatial residency and habitat usage, with a view to understanding the potential for impact between escaped farmed cod and wild cod and other fish species, particularly Atlantic salmon. Most of the tagged cod remained within a restricted corridor in the inshore zone, occupied deep water (75e130 m) within several kilometres of the release point, and undertook local movements. Three cod under-took more extensive movements; one fish emigrated offshore immediately, and two fish moved as far as 14 km from the release point before returning, 52e54 h later, to the area in which the other cod were located. The mean residence time in the inshore zone was 55 days. In the late autumn, there was a staggered pattern of departure from the coastal
