My research mainly focuses on the restoration of sturgeon populations in Northern Germany. From a management standpoint the activities in the adjacent seas and neighboring states are a logical component of the work when working with migratory species.
Restoration related fields such as physiology, behavior, rearing, habitat utilization, fisheries, and river restoration, are the key areas of the research contributing to management approaches. Recently, the sociological component of the restoration work both in theory and in practice comes into focus more intensively, since from a management perspective the active involvement of interest groups into restoration activities (from management to practical activities) and the potential benefits need a more focused approach in the range of both European and Baltic sturgeon.
