This paper looks at the rationale and methodology of the historical reconstruction of coastal ecosystems, and issues of ecological theory surrounding it, especially levels of production, trophic cascades, keystone species and local extinctions (extirpations).


Theoretical issues are exemplified using a pelagic zooplanktivorous fish, the herring, whose fisheries history can be traced back for over a thousand years.
