Alpine bullhead (Cottus poecilopus Heckel): a potential refuge for Gyrodactylus salaris Malmberg, 1957 (Monogenea)
(Peer reviewed; Journal article, 2019)The notifiable freshwater pathogen Gyrodactylus salaris Malmberg, 1957 tends to be a generalist in contrast to other monogeneans. Whilst it causes most damage to its primary host, the Atlantic salmon (Salmo salar Linnaeus), ... -
Bias in estimates of electrofishing capture probability of juvenile Atlantic salmon
(Journal article; Peer reviewed, 2018)We evaluated the effect of the total number of passes used, and the application of block nets, on multi-pass electrofishing removal sampling for estimating juvenile Atlantic salmon (Salmo salar L.) abundance and body size ... -
Climate-driven biophysical changes in feeding and breeding environments explain the decline of southernmost European Atlantic salmon populations
(Peer reviewed; Journal article, 2019)The consistency of the global declining trend of Atlantic salmon (Salmo salar) populations suggests that climate-driven reduced survival and growth at sea are the main driving factors. The southernmost populations have ... -
Coastal migration patterns of the four largest Barents Sea Atlantic salmon stocks inferred using genetic stock identification methods
(Peer reviewed; Journal article, 2019)Combining detailed temporal and spatial catch data, including catch per unit effort, with a high-resolution microsatellite genetic baseline facilitated the development of stock-specific coastal migration models for the ... -
Considering sampling bias in close-kin mark–recapture abundance estimates of Atlantic salmon
(Peer reviewed; Journal article, 2021)Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close-kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being ... -
Disputing nature in the Anthropocene: technology as friend and foe in the struggle to conserve wild Atlantic salmon (Salmo salar)
(Peer reviewed; Journal article, 2019)The Anthropocene, simply put, is characterized by the recognition that natural processes are inextricably entwined With human influence. Against this backdrop, managing natural resources needs to be fundamentally rethought ... -
‘Do you care about the river?’ A critical discourse analysis and lessons for management of social conflict over Atlantic salmon (Salmo salar) conservation in the case of voluntary stocking in Wales
(Peer reviewed; Journal article, 2019)1. Stakeholders with shared interests in fish conservation often disagree about which specific conservation measures are appropriate, leading to conflicts with sometimes long‐lasting and disruptive social and political ... -
