Metal content of kelp (Laminaria digitata) co-cultivated with Atlantic salmon in an Integrated Multi-Trophic Aquaculture system

This study provides the first comparative investigation of metals in seaweed from different cultivation environments and can be used to support best-practice management decisions involving IMTA. Laminaria digitata metal content was marginally increased for copper, manganese and vanadium at IMTA sites. Vanadium and antimony (emerging contaminants) in the commercially important seaweed L. digitata are reported for the first time.
