Coupling stable isotopes with bioenergetics to evaluate sources of variation in organochlorine concentrations in Baltic salmon (Salmo salar)
Atlantic salmon ( Salmo salar ) collected from three locations around the northern Baltic Sea in 2003–2004 showed large spatial and individual variation in their organochlorines (OCs) (polychlorinated dibenzo-p-dioxins and furans and polychlorinated biphenyls). This variation could be explained only...

A salmon bioenergetics accumulation model was used to evaluate the contribution of salmon growth and their diet to the observed individual variation in OC content. Our model revealed that the contribution of three main prey species in the OC accumulation of salmon varied markedly between the study areas. Amount of lipids in salmon explained a large proportion of their OC concentration.
