Autodiametric calibrations shown as scatter plots and fitted lines for Atlantic cod 
( Gadus morhua), European hake ( Merluccius merluccius), Atlantic herring < Clupea 
harengus), Atlantic mackerel ( Scomber scombrus ), European plaice ( Pleuronectes 
platessa), redfish (deep water redfish [Sebastes mentella] or golden redfish [Sebastes 
marinus ]) used to produce the autodiametric calibrations (Table 5) by Institutes 
AZTI (A stained Rose Bengal), Cefas (B stained with periodic acid Schiff’s, except 
European plaice with eosin), CSIC (C hake Rose Bengal, redfish unstained), and 
IMR (D unstained).
