Haddock 7b-k Combined IGFS-WIBTS-Q4 and EVHOE_WIBTS-Q4 surveys
The IGFS-WIBTS-Q4 and EVHOE-WIBTS-Q4 surveys have nearly full coverage of the haddock VIIb-k stock, with the exception of VIIef (Figure 1). The landings from VIIef have been fairly minor at around of 15% of the total landings from VIIb-k. Both surveys follow the IBTS manual on gear specification and fishing and sampling protocols. This document is aimed at investigating whether it would be appropriate to create a combined IGFS/EVHOE tuning index for the haddock VIIb-k assessment.
