Monitoring, aquatic ecology investigations & data analysis

In order to achieve the objectives of the European Water Framework Directive (EG-WRRL), under the implementation of the European legislation on the protection of flora and fauna (Fauna-Flora-Habitat-Richtlinie, FFH), IGF Jena offers a variety of services such as: a) evaluation and documentation of the faunistic and morphological status of riverine and lacustrine systems, b) evaluations of the success of restoration projects, among others.

Our services include:


Surveys and reports on the fish stock in lotic (e.g. rivers and creeks) and lentic (e.g. lakes and fishing ponds) systems
