Description
Summary:There has been no stock-recruit relationship accepted for Subarea 2+3KLMNO Greenland halibut in past stock assessments. There has been considerable uncertainty about the reproductive biology of the species and in the past the data did not indicate a relationship between the biomass of older fish and recruitment. We re-examine this relationship using data from the last 7 assessments of the stock as well as retrospective analyses of the most recent assessment. We show that there is clearly a relationship between older biomass and recruitment for this stock with implications for recruitment overfishing.
