Nordic science group on tagging compilation for Greenland halibut (GHLTAG) (39759)

Project Details

Description

Results from mark-recapture studies suggest that Greenland halibut in the North Atlantic migrates long distances during its lifetime and across the present management areas and defined stock areas. This his expected to affect the quality of stock assessments and advice on fishing opportunities. The lack of incorporating this uncertainty quantitatively into the stock assessments may result in inaccurate stock development perceptions. Subsequently, this might result in inappropriate management of fisheries and increase the risk of local depletion with substantial implications for the coastal communities. This project therefore re-examine historic tagging experiments as conducted by all North Atlantic marine science institutes by compiling all tag recapture data. Comprehensive analyses will likely through new light on Greenland halibut stock entities and their dynamics in the North Atlantic. At two workshops the common analyses and results will be presented.
