Biodiversitaet in der Nordsee

Description: Das Projekt verbindet Trends in der Biodiversitaet von Fischen und Epibenthos mit den Entwicklungen im Fischereiaufwand in der Nordsee. Methoden fuer ein verbessertes biologisches Monitoring werden entwickelt. Ziel: Verbesserung des europaeischen Fischereimanagementmethode: Auswertung von internationalen Grundfischsurveys.

  Title: Monitoring Biodiversity in the North Sea Using Groundfish Surveys
  Description: Several nations undertake ground-fish surveys in the North Sea. This 3-year project is intended to show how value may be added to these surveys by monitoring biodiversity of non-commercial species in support of the Convention on Biological Diversity (Rio de Janeiro, 1992). The project is divided into four tasks. Firstly, existing ground-fish survey data on non-commercial fish, and where possible, epibenthic invertebrates, were analysed for information on biodiversity. It was concluded, as expected, that fish survey trawls are not good sampling tools for monitoring biodiversity. Secondly, a 2-metre beam trawl constructed from steel was tested at stations throughout the North Sea, and found to be a rugged and dependable survey tool for epibenthic biodiversity. Attempts are now being made to standardise towing distances. Thirdly, taxonomic material is being prepared to assist scientists on ground-fish surveys to readily identify benthic species caught by the beam trawl. This is taking the form of a computerised database with photographs. A fourth task, to be addressed in the final year of the project is the development of protocols for the reporting and assessment of trends in biodiversity so that the results of any future monitoring can be as relevant and accessible as possible. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=75055
