Erarbeitung eines fischökologischen Bewertungsschemas für Österreich und Slowenien für die Umsetzung der WRRL (Fibewas)

Description: Die Erhebung des Fischbestandes und die fischökologische Bewertung des gemeinsamen Grenzwasserkörpers der Drau zwischen Lavamünd und Dravograd war Ziel des Projektes FIBEWAS (EU-Interreg IIIA Österreich - Slowenien). Die fischökologischen Erhebungen wurden im Zeitraum von Mai 2006 bis Mai 2007 durchgeführt, wobei die Effizienz unterschiedlicher Befischungsmethoden geprüft wurde. Die gewonnenen Erfahrungswerte können bei zukünftigen fischökologischen Bewertungen im Zuge der Umsetzung der Wasserrahmenrichtlinie in großen Staurumen eingesetzt werden.

  Title: Development of a fish-ecological assessment scheme for Austria and Slovenia for the implementation of the WFD
  Description: Fishecological evaluation scheme for Austria (A) and Slovenia (S): FIBEWAS. The Austrian - Slovenian Commission for the Drava River has been operating a chemical-physical monitoring program of the Drava River for more than 50 years. However, scientific fish-ecological investigations have been missing in the border area.For the investigation of the common water body, as well as for the development of a fish - based assessment method for the ecological status of rivers for Austria and Slovenia, the Interreg III A-Project FIBEWAS was developed and approved by the European Union.With application of different fishing methods the reservoir Dravograd was investigated in the year 2006 and 2007 three times (spring 2006/autumn 2006Ispnng 2007). The method selection took place according to the Austrian Federal Ministry of Agriculture, Forestry, Environment and Water Management: manual for field research of biological quality elements, part Al - fish. In order to establish a reference fish assemblage for the Drava river, historical data about the fish population in the section were collected. These data refer to the time before the substantial anthropogenic interferences took place, i. e. before 1850. Altogether 31 fish species could be proven. From the 31 proven species only 21 species are autochthon, the remaining 10 species are aUochthonous. Dominant species in the water body are chub (Squalius cephalus), followed by spirlin (Alburnoides bipunctatus), bieak (Alburnus alburnus) and nase (Chondrostoma nasus), roach (Rutilus rutilus), barbel (Barbus barbus) and white finned gudgeon (Romanogobio vladykovii). Bitterling (Rhodeus amarus), danube roach (Rutilus virgo), pike (Esox Iucius), rudd (Scardinius erythrophthalmus) and perch (Perca ffuviatilis) are to be found regularly. Remaining fish species were found rarely and/or in isolated instances.Under the threatened species the danube roach (Rutilus virgo) is still comparatively frequent in the lower Drava river. Main tasks of the project were the fish-ecological evaluation of the common water body of the Drava, the collection of a fish data for the Austrian-Slovenian Drava Commission, arid gain of experience regarding the implication of the Water framework directive on large rivers. An evaluation of the Austrian fishecological evaluation method (FIA) showed that the good ecological status could not be achieved in this water body, in particular due to the relatively small fish biomasses. However, the common waterbody of the Drava river is classified as heavily modified in the sense of the EC-Waterframework Directive. For the moment there exists no assessment scheme to determine the ecological potential of this type of water bodies in both countries. As for a preliminary expert evaluation our resultsindicate a good ecological potential at least for the upstream water body, which represents the head of the impoundment. https://ufordat.uba.de/UFORDAT/pages/PublicRedirect.aspx?TYP=PR&DSNR=1038478
