Summary

The authors assessed accurate reporting of seabird bycatch in the Greenland halibut (Reinhardtius hippoglossoides) fishery in northern Canada. The amount of bird bycatch reported by at-sea observers and carcass collections yielded different (0.5-11-fold higher) results from that of the at-sea observers database. This highlights huge discrepancies in methods which suggest that seabird bycatch data is not accurate.
