Genetic Diversity of European Grayling and Tench
The
conservation of biological diversity and the use of biological resources in a
sustainable manner are not only an objective of the Convention on Biological
Diversity, but also a common concern of humankind. To achieve this goal and to
better assess e.g. the potential impact of human-induced global change on
biodiversity, it is necessary to gather information about the genetic diversity
of natural and cultivated species.
Within
this project, on behalf of the Federal Office for Agriculture and Food
(Bundesanstalt für Landwirtschaft und Ernährung, BLE), we are estimating the
genetic diversity of the European Grayling (Thymallus
thymallus) and the Tench (Tinca tinca)
in German river basins. These data will provide the basis of recommendations
for future management of Grayling and Tench fisheries in Germany.
To assess
the genetic diversity of about 30 populations originating from the main river
catchment areas in Germany we are using mitochondrial as well as microsatellite
markers. This project started at the beginning of 2016 and is realized in collaboration
with Thomas Schiller and Christoph Köbsch from the Institute of Hydrobiology,
TU Dresden.
