List of publications, reports and talks since 2004:
Beside the thesis of Diploma und Doctoral thesis, 15 publications in international peer-reviewed journals   as lead or co-author have been published to date. Some grant proposals, published or internal reports and other  non peer-reviewed publications have been established through collaboration with international (ORBICON, FeBEC, DEVSTAT), national (GOPA, Cofad) and regional (CRM, GMA) economic or consultance partners. >45 presentations (as talks or posters) have been given either intelligible to the broad public, or on national (LLUR, LKN SH, Thünen Institut) and international working group level (ICES, EU, PICES) and as well as on national (GfÖ, DGL, AFGN) or international scientific conferences (ICES, CIESM, ASLO, ALFC). One important aspect is to transfer & communicate the scientific findings to the broad audience (e.g through the Internet, l LSFV S-H or angling magazines, other organisations broschures and papers like the Fischerblatt or Bauernblatt).
