Social network analysis of the behavioural interactions that influence the development of fin damage in Atlantic salmon parr (Salmo salar) held at different stocking densities
Social network analysis of behavioural interactions was used to quantify the effect of high (HD, 30 kg m-3) and low (LD, 8 kg m-3) stocking densities on the frequency and severity of fin damage in Atlantic salmon. Dorsal fin damage (erosion, splits, fin index) was significantly higher in HD compared to LD groups with higher amounts of dorsal fin […]
Investigating the influence of predictable and unpredictable feed delivery schedules upon the behaviour and welfare of Atlantic salmon parr (Salmo salar) using social network analysis and fin damage
Social network analysis was utilised to quantify the effect of short-term predictable (PD) and unpredictable (UD) feed delivery schedules of 10 days on behavioural interactions and the frequency and severity of fin damage in Atlantic salmon. Fin damage was only observed on the dorsal fin and its frequency and severity was significantly higher in UD […]
Animal welfare: a social networks perspective
Social network theory provides a useful tool to study complex social relationships in animals. The possibility to look beyond dyadic interactions by considering whole networks of social relationships allows researchers the opportunity to study social groups in more natural ways. As such, network-based analyses provide an informative way to investigate the factors influencing the social […]
