Blue whiting ( Micromesistius poutassou ): behaviour and distribution in Greenland waters
As a result of climate variations, organisms are in a constant race for adapting to environmental changes, and for many species, the geographical distribution follows the climate. Climate changes have accelerated in recent decades, and particularly in Arctic and subarctic areas. These regions are fu...

As a result of climate variations, organisms are in a constant race for adapting to environmental changes, and for many species, the geographical distribution follows the climate. Climate changes have accelerated in recent decades, and particularly in Arctic and subarctic areas. These regions are further projected to undergo some of the largest climate and ecosystem changes on Earth. Changes in the occurrence and distribution of important commercial species are among the ongoing and expected future changes. This has consequences for fisheries and communities that depend on them. Fluctuations in the abundance and distribution of fish between territorial waters may prevent nations from maintaining the exploitation of the resources, whereas it may allow for others to access them. This has already resulted in some countries experiencing a decline in traditional fisheries, while others have embarked on new ones, such as seen with the pelagic fishery in Greenland. Blue whiting is one of the species that the Greenlandic fishing industry have observed with great anticipation, as numbers have increased among bycatches. This thesis depicts my work describing the biology and distribution of the small gadoid fish blue whiting (Micromesistius poutassou, Risso) in Greenland waters. The work resulted in three papers, of which two have been published in scientific journals, while the third is in review.
