AbstractFishmeals produced from herring (Clupea harengus), mackerel (Scomber scomber), capelin (Mallotus villosus) and Norway pout (Gadus esmarki) were analysed by neutron activation. The elements tested were mercury, bromine, arsenic, selenium, antimony, copper, cobalt, iron, zinc, molybdenum and tungsten. The distribution of these elements in the solid and aqueous phases in boiled fish used as raw material for fishmeal was also studied.
