The behaviour of the Burrishoole salmon ranch strain, released from a non-native system, was compared with behaviour in its native system. The study showed that the juvenile Burrishoole salmon required a period of acclimation at the remote site prior to release due to the elevated stress levels associated with the transfer. Underwater observations showed that some of the reared smolts also required a period of acclimation after release. Results from the Irish coded wire tagging programme show the exploitation of Burrishoole fish, released at the remote site, in the Irish coastal drift net fishery occurred over a wide area along the Irish coast. Burrishoole adults returned to the location of release rather than their native system. The number of Burrishoole adults recaptured in freshwater from other systems was low and was dependent on local environmental conditions. A greater rod catch of Burrishoole fish was recorded in the non-native system.
