Mitochondrial haplotype diversity in 27 populations of brown trout, Salmo trutta L., in Austria was investigated by sequencing the 5' end of the mitochondrial DNA (mtDNA) control region. Although all populations are within the Danube drainage, 44% of all individuals carried Atlantic basin haplotypes. It is argued that the presence of these haplotypes in(More)
Large rivers are worldwide under severe pressure and there is a lack of information on large river restoration. The present paper represents a meta-analysis of available data on river rehabilitation projects performed at the Austrian Danube River consisting of six rehabilitation projects addressing 19 sites. The overall goal was to analyse the response of(More)
During the last two decades theoretical and applied limnological research increasingly focused on the investigation of floodplain rivers (Amoros & Roux 1988, Junk et al. 1989, Schiemer 1999, Ward et al. 1999, Findlay et al. 2002). Ecological key prerequisites of such systems are natural fluvial dynamics leading to flood-controlled disturbances, thereby(More)
The pressures and impacts on the World’s Large Rivers have increased greatly in recent years, as a consequence of their exploitation to meet various human needs. Large rivers are particularly exposed to problems of multiple uses, often with conflicting aims. At the global scale, river systems are altered by increased nutrient loads leading to eutrophication(More)
Size structure data particularly that of length and weight is very important fisheries management tool, which is also applied to assess the health, habitat and integrity of the rivers. Nepal is tremendously rich in both fisheries and water resource and thus, this analysis is very important. However, this kind of analysis is not common in fisheries studies(More)
