About the thesis

​The copepod genus Calanus or “Raudåte” by Norwegian name is an ecologically important marine species in the Northern Seas (North Atlantic, Arctic, and Northern Pacific). Calanus species play a key role in ene​rgy transfer in marine food webs, both as primary consumers and as prey for fish, seabirds, and other marine predators. Commercially, they have been a great source of Omega-3 fatty acid. 

Despite their ecological and commercial importance, species-level taxonomy in the genus Calanus remains challenging because of their identical morphology, overlapping distribution, huge genome sizes, and limited genomic and
transcriptomics resources. Species-level identification in the genus Calanus is very important for their proper conservation and management. 

The current fisheries regulations in Norway only focuses on a single species, C. finmarchicus. However, recent genetic analyses using few molecular markers have shown overlapping distribution for at least several species across the Northern Seas, including the Norwegian fjords. 

This thesis addressed some of these specieslevel taxonomy problems present in the genus Calanus using genomics and transcriptomics approaches, which aides in the proper understanding of their ecology and evolution. Results of these studies may also have implications in the current fisheries regulations implemented
in the country.​
