【 摘 要 】

ABSTRACT: The substitution of fish oils and fish meal with terrestrial components in the diets of farmed fin-fish offers a unique opportunity to trace organic effluents from fin-fish aquaculture into the marine environment. In this study, we compared 3 techniques—the detection of soya DNA, fatty acids and stable isotopes—for tracing terrestrial components from fin-fish diets and fecal material passing from a coastal salmonid farm in Norway into the marine environment, i.e. seston traps and sediment, and then into benthic fauna, represented by the king scallop
