An industry-scale mass marking technique for tracing farmed fish escapees
Warren-Myers, Fletcher; Dempster, Tim; Fjelldal, Per Gunnar; Hansen, Tom; Swearer, Stephen E. (Journal article; Peer reviewed, 2015-03-04)Farmed fish escape and enter the environment with subsequent effects on wild populations. Reducing escapes requires the ability to trace individuals back to the point of escape, so that escape causes can be identified and ... -

Limited evidence for differential reproductive fitness of wild Atlantic cod in two areas of high and low salmon farming density
Barrett, Luke; Swearer, Stephen E.; Harboe, Torstein; Karlsen, Ørjan; Meier, Sonnich; Dempster, Timothy David (Journal article; Peer reviewed, 2018)Sea cage fish aquaculture attracts large aggregations of wild fish that feed on farm waste.

Stable isotope marking of otoliths during vaccination: a novel method for mass-marking fish
Warren-Myers, Fletcher; Dempster, Tim; Fjelldal, Per Gunnar; Hansen, Tom; Jensen, Arne J.; Swearer, Stephen E. (Journal article; Peer reviewed, 2014-06-04)Tagging or marking of fishes enables the collection of population-based information for ecological research, yet few techniques enable 100% mark detection success. We tested a new mass-marking technique: otolith marking ...
