Identification and Modelling of a Representative Vulnerable Fish Species for Pesticide Risk Assessment in Europe
Identification and Modelling of a Representative Vulnerable Fish Species for Pesticide Risk Assessment in Europe Von der Fakultät für Mathematik, Informatik und Naturwissenschaften der RWTH Aachen University zur Erlangung des akademischen Grades eines Doktors der Naturwissenschaften genehmigte Dissertation vorgelegt von Lara Ibrahim, M.Sc. aus Mazeraat Assaf, Libanon Berichter: Universitätsprofessor Dr. Andreas Schäffer Prof. Dr. Christoph Schäfers Tag der mündlichen Prüfung: 30. Juli 2015 Diese Dissertation ist auf den Internetseiten der Universitätsbibliothek online verfügbar Erklärung Ich versichere, dass ich diese Doktorarbeit selbständig und nur unter Verwendung der angegebenen Hilfsmittel angefertigt habe. Weiterhin versichere ich, die aus benutzten Quellen wörtlich oder inhaltlich entnommenen Stellen als solche kenntlich gemacht zu haben. Lara Ibrahim Aachen, am 18 März 2015 Zusammenfassung Die Zulassung von Pflanzenschutzmitteln in der Europäischen Gemeinschaft verlangt unter anderem eine Abschätzung des Risikos für Organismen in der Umwelt, die nicht Ziel der Anwendung sind. Unvertretbare Auswirkungen auf den Naturhalt sollen vermieden werden. Die ökologische Risikoanalyse stellt die dafür benötigten Informationen durch eine Abschätzung der Exposition der Organismen und der sich daraus ergebenden Effekte bereit. Die Effektabschätzung beruht dabei hauptsächlich auf standardisierten ökotoxikologischen Tests im Labor mit wenigen, oft nicht einheimischen Stellvertreterarten. In diesen Tests werden z. B. Effekte auf das Überleben, das Wachstum und/oder die Reproduktion von Fischen bei verschiedenen Konzentrationen der Testsubstanz gemessen und Endpunkte wie die LC50 (Lethal Concentrations for 50%) oder eine NOEC (No Observed Effect Concentration, z. B. für Wachstum oder Reproduktionsparameter) abgeleitet. Für Fische und Wirbeltiere im Allgemeinen beziehen sich die spezifischen Schutzziele auf das Überleben von Individuen und die Abundanz und Biomasse von Populationen. -
The Irish Pollan, Coregonus Autumnalis: Options for Its Conservation
Journal of Fish Biology (2001) 59 (Supplement A), 339–355 doi:10.1006/jfbi.2001.1755, available online at http://www.idealibrary.com on The Irish pollan, Coregonus autumnalis: options for its conservation C. H*¶, D. G*, T. K. MC† R. R‡ *School of Environmental Studies, University of Ulster, Coleraine, BT52 1SA, U.K., †Zoology Department, National University of Ireland, Galway, Republic of Ireland and ‡Department of Agriculture and Rural Development, Newforge Lane, Belfast, BT9 5PX, U.K. The ecology of four relict Irish populations of pollan (Coregonus autumnalis) is compared with that of the species elsewhere, and used to advocate conservation. The threats to these populations from introduced/invasive species, habitat degradation, climate warming and commercial exploitation are summarized and the legislation governing conservation of the stocks is reviewed. Conservation options (legislation, habitat restoration, stock translocation and stock augmentation) are outlined and their practicality and efficacy considered. A preliminary search indicates that there are a number of lakes that appear to be suitable for pollan translocation. 2001 The Fisheries Society of the British Isles Key words: Coregonus autumnalis; conservation ecology; legislation; eutrophication; translocation. INTRODUCTION Owing to its recent glacial history, Ireland has a depauperate native freshwater fish fauna of only 14 species, all of euryhaline origin. Human introductions have augmented the Irish ichthyofauna and today 25 species are found in Ireland’s fresh waters (Griffiths, 1997). Of the native species, only one, the pollan Coregonus autumnalis Pallas is not found elsewhere in Europe (Whilde, 1993). Ireland has more than 4000 loughs (lakes) >5 ha, but pollan occur in only four large lowland loughs. -

The last remaining indigenous population of North Sea houting is found in the River Vidaa, Denmark. Despite legislative protection and numerous stocking and habitat restoration programmes, including a €13.4 million EU Life resto- ration project, populations are declining in most rivers in Denmark. Limited knowledge of the general biology of the species, in particular of the early life history stages and habitat require- ments, is a serious impediment to management and conservation. In this study, we investigated larval and juvenile salinity tolerance, providing novel information on the early life stages of North Sea houting. Results revealed an ontogenetic differentiation in salinity tolerance when comparing newly hatched larvae, larvae at later developmental stages and juveniles expected to initiate migration to the Wadden Sea. -
