One of my main responsibilities is to improve our knowledge of the biology and ecology, as well as the fishery of the european hake ( Merluccius merluccius) in Norwegian fjords and coastal waters, as well as the North Sea / Skagerrak. Part of this will be a tagging study (2014-2016) conducted on the west coast of Norway, which is envisaged to produce data pertaining to general biology, growth (provided fish are recaptured), behaviour, and horizontal and vertical migration patterns. Additionally, several projects have been initiated and will focus on ageing of hake in Norwegian fjords, the genetis of hake in the North Sea and Norwegian coastal waters, and spatio-temporal trends in the Norwegian hake fishery.
As a member of the ICES WGNSSK I am also part of a inhouse group responsible for giving advice on the sustainable mangement of several demersal fish stocks harvested in the North Sea.
