Science / project plan

The PhD-project focuses on migration and stock structure for one of the most important coastal fish species in the Greenlandic ecosystems, namely capelin (Mallotus villosus). State-of-the-art trace element analysis (LA-ICP-MS) of earstones (otoliths) is used to follow migration of individuals and interspecies mixing with adjacent fjord populations. Capelin will be caught from a range of localities along the coastline of West-, South- and East Greenland, in order to form a complete picture of capelin migratory behavior and stock composition in Greenland.

The objective of the project is to enable and strengthen local authorities to manage ecosystem services, including fisheries and ecosystem functioning, related to capelin sustainably and optimally.

The project will be carried out at Danish Technical University (DTU AQUA) in collaboration with stakeholders at local, national and international level as well as the Greenland Institute of Natural Resources (GINR), the Geological Survey of Denmark and Greenland (GEUS). The project is partially funded by Polar Seafood Greenland A/S, Royal Greenland A/S and GrønlandsBANKENs Erhvervsfond
