Description:

Atlantic salmon (Salmo salar) are reared in marine net-pens and may escape due to operational errors and structural failures. The fate of these fish is poorly understood. This study sought to identify spatial patterns and the fate of Atlantic salmon post-smolts following a simulated escape event from an aquaculture site in the Bay of Fundy, Canada. Farm-raised salmon (N = 99) were implanted with an acoustic tag and released from a commercial aquaculture facility with their movement patterns and mortality tracked over a 4-month period. Fish took ∼5 h to leave the release site and initially opted to either move inshore (N = 8) or out to sea (N = 73). Although, many fish returned to the release site. Most fish (72.7%) succumbed to predation shortly after release (64% by 48 h). Together, site fidelity and early stage predation could substantially reduce the ecological risks associated with farm-raised salmon that escape from commercial aquaculture facilities.
