Based
on a number of unrelated fish monitoring programs, the QSR 2004
described and assessed the temporal trends and spatial distribution
of 20 fish species and the brown shrimp (Crangon crangon).
Because of the unrelatedness of these monitoring programs it
underlined the need for a regular assessment of the fish fauna and
formulated recommendations on management, monitoring and research.
These
were adopted in the recommendations of the 11th
International Scientific Wadden Sea Symposium in Esbjerg (April
2005), and it was advised to include fish monitoring in the ongoing
Trilateral Monitoring and Assessment Program (further indicated as
TMAP) revision process. As a result of the QSR 2004 and the
recommendations following from the Trilateral Ministers Conference
2005, a TMAP ad hoc expert group on fish monitoring was established
in March 2006.
For
the first time, the QSR 2009 provided a comprehensive and harmonized
analysis of the fish fauna of the entire Wadden Sea.
