The Invasion of Prussian Carp (Carassius gibelio) in western North America
Prussian carp is recognized as one of the most dangerous invasive
species (Kalous et al. 2004). Their success in new
habitats can be attributed to their ability to tolerate a wide range of
environmental stressors, broad omnivorous diet and asexual means of reproduction
(Balik et al. 2003, Liasko et al. 2011, Tsoumnai et al. 2006). Since the first sighting in 2000, Prussian
carp have rapidly colonized artificial and natural waterways with in
south-central Alberta, Canada. The uncontrolled spread of Prussian carp could
pose a serious threat to native fish communities. For this reason, it is important to assess their current distribution and movement patterns throughout south-central Alberta. This will be done using all known locations since 2000 to generate maps in ArcMap. Additionally, it is pertinent to determine whether the presence of Prussian carp has resulted in changes in native fish community and if there are specific habitat or environmental parameters that can predict Prussian carp presence. Data collection for this involved gathering fish abundance and habitat data in 43 streams in the Red Deer Watershed, Alberta, Canada using electrofishing techniques. Knowing this information will help managers make more informed decisions that may prevent or slow the establishment of Prussian carp in Alberta 'sprairie streams.
