Marine chemistry variation along Greenland’s coastline indicated by chemical fingerprints in capelin ( Mallotus villosus ) otoliths
The small pelagic fish capelin (Mallotus villosus) is widely distributed in the Arctic, where it plays a central role in the marine food web as prey for numerous fish, birds, and mammals. Sustainable fisheries management advice for capelin that spawn in Greenland is non-existent due in part to a lac...

The small pelagic fish capelin (Mallotus villosus) is widely distributed in the Arctic, where it plays a central role in the marine food web as prey for numerous fish, birds, and mammals. Sustainable fisheries management advice for capelin that spawn in Greenland is non-existent due in part to a lack of biological information on population structure and spatial dynamics. This study provides a chemical baseline for investigations of migration and population structure of capelin and potentially other marine organisms in Greenlandic waters, using chemical tracers in otoliths from 549 spawning capelin, collected from 18 localities along Greenland's coastline. Abundances of 14 elements were measured in otolith edges, and geographic variations were demonstrated for Li, Ba, Sr, Pb, Mg, P, Zn, and Mn.
