# The pattern on all three of its own queries at once: a 2004 observation of the North Sea herring
# stock whose exploitation rate is 'Moderate fishing mortality' and whose state is 'Fully
# exploited'. Beside it stands the survey observation behind the figures, made by the ICES herring
# assessment group over the North Sea.
