Dietary Trace Metal Supplements Promote Blood Vessel Melanosis in Fillets of Juvenile Farmed Atlantic Cod, Gadus morhua L.
Chronic over‐exposure to diet‐borne copper has been implicated in the development of black stripes caused by melanin deposits (melanosis) around the blood vessels in fillets of farmed Atlantic cod, Gadus morhua L. To test this hypothesis a 6‐mo pilot study using feeds containing controlled amounts o...
