In the case of Baltic herring in the Baltic Main Basin, the assessment unit is directly comparable to the units used by the Baltic Fisheries Assessment Working Group; although at their 2001 meeting WGBFAS (2001) used new stock assessment units for Baltic herring in the Main Basin. As the sprat population in Sub-division 30 is rather low and in Sub-division 31 almost non- existing, the Baltic Main Basin stock estimates are basically also referring to Sub-divisions 25–32. Consequently the effect of ignoring the two Sub-divisions should not hamper a direct comparison between single species and multispecies assessment output in the case of cod and sprat.
