Biomagnification and polychlorinated biphenyl congener distribution in an aquatic predator‐prey, host‐parasite system
Abstract Biomagnification and polychlorinated biphenyl (PCB) congener distribution was examined in a predator‐prey, hostparasite system, in which Atlantic salmon ( Salmo salar ) preyed upon sprat ( Sprattus sprattus ). Eubothrium crassum was an intestinal parasite in salmon that also “preyed upon” s...
