Area use and movement patterns of wild and escaped farmed Atlantic salmon before and during spawning in a large Norwegian river
(Journal article, 2016)We compared the within-river movements and distribution of wild and escaped farmed Atlantic salmon Salmo salar before and during spawning in the Namsen river system of Central Norway. A total of 74 wild and 43 escaped ... -
AS WE SEE IT Reared fish, farmed escapees and wild fish stocks-a triangle of pathogen transmission of concern to Mediterranean aquaculture management
(Peer reviewed; Journal article, 2013)Although aquaculture in the Mediterranean is a relatively young industry, finfish dis eases have been reported to cause considerable problems and mortalities among the farmed stocks. In general, the farming activity and ... -
Behaviour and survival of wild Atlantic salmon Salmo salar captured and released while surveillance angling for escaped farmed salmon
(Journal article; Peer reviewed, 2017)In many Norwegian rivers, spawning stocks are surveyed for escaped farmed salmon with surveillance fishing by rod and reel after the recreational angling season. However, the benefits of surveillance fishing depend on the ... -
Effects of salmon lice infection on the behaviour of sea trout in the marine phase
(Peer reviewed, 2014)Salmon lice Lepeophtheirus salmonis Krøyer may affect survival and growth of anadromous salmonids through physiological stress and/or behavioural changes. Using acoustic telemetry tracking, we investigated the behaviour ... -
Effects of salmon lice Lepeophtheirus salmonis on wild sea trout Salmo trutta—a literature review
(Peer reviewed; Journal article, 2015)Salmon farming increases the abundance of salmon lice, which are ectoparasites of salmonids in the sea. Here we review the current knowledge on the effects of salmon lice on wild sea trout. Salmon lice feed on host mucus, ... -
Escape history and proportion of farmed Atlantic salmon Salmo salar on the coast and in an adjacent salmon fjord in Norway
(Peer reviewed; Journal article, 2020)To gain more knowledge about escaped farmed salmon Salmo salar in the wild, we investigated the proportion of escapees, body length at escape, proportion escaped as smolts/post-smolts (≤300 mm) and number of winters in the ... -
Escaped farmed Atlantic salmon grow, migrate and disperse throughout the Arctic Ocean like wild salmon
(Peer reviewed; Journal article, 2013)This paper describes the first observations of escaped farmed Atlantic salmon Salmo salar in the Arctic Ocean. Among 138 individuals of Atlantic salmon captured at the west coast of the Spitsbergen Island at Svalbard in ... -
Genetic evidence of farmed straying and introgression in Swedish wild salmon populations
(Peer reviewed; Journal article, 2021)Escaped farmed Atlantic salmon represent a well-documented and ongoing threat to wild conspecific populations. In Norway, the world-leading producer of farmed salmon, annual monitoring of straying and genetic introgression ... -
Impacts of wild fishes attracted to open-cage salmonid farms in Norway
(Journal article; Peer reviewed, 2014)Salmonid farming affects both the environment and other industries, with impacts of wild fish attracted to fish farms being a major concern. Here, we summarized existing knowledge on the impacts of such aggregations around ... -
Maternal inheritance influences homing and growth of hybrid offspring between wild and farmed Atlantic salmon
(Journal article; Peer reviewed, 2017) -
Salmon lice sampled from wild Atlantic salmon and sea trout throughout Norway display high frequencies of the genotype Associated with pyrethroid resistance
(Journal article, 2019)Atlantic salmon Salmo salar aquaculture is based on the use of open-pen sea cages, with the consequence that farmed fish are both recipients and sources of pathogens from surrounding waters. Currently, the parasitic salmon ... -
Salmon louse infestation in wild brown trout populations generates multi-modal mixture distributions
(Peer reviewed; Journal article, 2020)For successful evaluation of the overall effects of salmon louse infestation on brown trout population dynamics, it is crucial to have a realistic understanding of how lice infestation distributions are generated and how ... -
Sea duck predation in mussel farms: the best nets for excluding common eiders safely and efficiently
(Peer reviewed; Journal article, 2013)Shellfish aquaculture is a growing food-producing sector. The blue mussel Mytilus edulis is the primary farmed shellfish and is also a main prey for various species of sea ducks. With their large density of high-quality ... -
Sea lice in Iceland: assessing the status and current implications for aquaculture and wild salmonids
(Journal article; Peer reviewed, 2019)This is the first in-depth study which quantifies lice infestation levels on wild and farmed salmonids in a fjord system in Iceland (Arnarfjörður, Westfjords) and gives a baseline for the assessment of sea lice infestation ... -
Stable isotope marking of otoliths duringvaccination: a novel method for mass-marking fish
(Peer reviewed; Journal article, 2014)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 ... -
Statistical and ecological challenges of monitoring parasitic salmon lice infestations in wild salmonid fish stocks
(Peer reviewed; Journal article, 2015)Ecological monitoring programmes should provide precise data to inform management, but the data quality is often limited by methodological challenges and the need for cost-effective sampling. Parasite infestations are ...
