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 ... -

Full production cycle, commercial scale culture of salmon in submerged sea-cages with air domes reduces lice infestation, but creates production and welfare challenges
Warren-Myers, Fletcher; Vågseth, Tone; Folkedal, Ole; Stien, Lars Helge; Fosse, Jan Olav; Dempster, Tim; Oppedal, Frode (Peer reviewed; Journal article, 2021)Structural modification of sea cages is continually changing to counter major production issues associated with commercial salmon farming. For example, snorkels and skirts are added to cages to reduce salmon lice infestations, ... -
Sentinels in Salmon Aquaculture: Heart Rates Across Seasons and During Crowding Events
Warren-Myers, Fletcher; Hvas, Malthe; Vågseth, Tone; Dempster, Tim; Oppedal, Frode (Peer reviewed; Journal article, 2021)Advances in tag technology now make it possible to monitor the behavior of small groups of individual fish as bioindicators of population wellbeing in commercial aquaculture settings. For example, tags may detect unusual ... -
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 ... -
Submerged cage aquaculture of marine fish: a review of the biological challenges and opportunities
Sievers, Michael; Korsøen, Øyvind Johan; Warren-Myers, Fletcher; Oppedal, Frode; Macauley, Georgia; Folkedal, Ole; Dempster, Tim (Peer reviewed; Journal article, 2021)Surface-based cages are the dominant production technology for the marine finfish aquaculture industry. However, issues such as extreme weather events, poor environmental conditions, interactions with parasites, and conflicts ... -
Tag use to monitor fish behaviour in aquaculture: a review of benefits, problems and solutions
Macaulay, Georgia; Warren-Myers, Fletcher; Barrett, Luke T.; Oppedal, Frode; Føre, Martin; Dempster, Tim (Peer reviewed; Journal article, 2021)A variety of tagging techniques are now available to monitor fish behaviour, physiology and their environmental experience. Tagging is frequently used in aquaculture research to monitor free-swimming individuals within ...
