“…However, studies done on other canal systems around the world indicate that canal habitats are very similar to lowland river habitats, and can in fact support a wide variety of species (Arlinghaus et al 2002;Borcherding et al 2002;Poulet et al 2005). This was clear in our study, as we observed 17 of the 30 species of fish commonly found in the Ottawa region (Poulin 2001).…”

The historic Rideau Canal (built in the 1800s) in eastern Ontario, Canada is a heavily managed and engineered ecosystem, popular for recreational boating and sport fishing in the summer and ice skating in the winter. However, little is actually know about the fish and aquatic macrophyte communities, particularly in the urban reach in Ottawa between Hartwell's Lock and the outflow of Dows Lake. The objective of this study was to examine the extent to which fish and macrophytes varied among different natural and engineered habitat/substrate types across the period when the canal is at navigational water levels. Five gross habitat types were identified, consisting of gravel, silt/sand, rip-rap/ gabion basket, boulder and concrete wall habitats. Replicate transects were established in the littoral zone, representing the different habitat types. Snorkel surveys were conducted on a biweekly basis, where fish species and aquatic macrophytes within the transects were quantified. Supplementary data on fish populations was obtained through seine net sampling as well as angler interviews and visual observations. The fish community was characterized as a reasonably simple warmwater assemblage, dominated by centrarchids (e.g., pumpkinseed [Lepomis gibbosus], bluegill [L. macrochirus], and largemouth bass [Micropterus salmoides]). In fact, more than 90% of all fish encountered (snorkel surveys and seine netting) belonged to the centrarchid family. None of the 17 fish species encountered in the reach were considered "at risk" in Canada, although the system supports one of the few urban muskellunge (Esox masquinongy) populations in the world and provides a range of urban recreational fishing opportunities for sportsfish. Fish diversity metrics (e.g., diversity, richness, evenness) varied little among habitat types, perhaps reflecting the fact that vegetation communities were reasonably homogeneous, largely Urban Ecosyst (2010) 13:563-582

“…Differences in feeding habits among sites were influenced by the presence of riparian vegetation. It is known that processes that occur in riparian zones influence the aquatic biota (GREGORY 1992, PUSEY & ARTHINGTON 2003 and lead to changes ZOOLOGIA 27 (2): 191-200, April, 2010 in the diet of different fish species (see WAITE & CARPENTER 2000, FERREIRA et al 2002, reinforcing its importance as a buffer zone (BOJSEN & BARRIGA 2002, SWEENEY et al 2004, POULET et al 2005. It is important to mention that the presence of arboreal riparian vegetation, even in poor state of conservation, provided distinct feeding resources to the fish fauna, reinforcing the findings of a previous study carried out by the authors of this paper (CENEVIVA-BASTOS & CASATTI 2007).…”

The habitat use and feeding habits of a set of nektonic fish species often found in small low-gradient streams in Brazil were investigated. The core species in the present study was Knodus moenkhausii (Eigenmann & Kennedy, 1903), the most abundant of five species in the nektonic guild. Records of the species in 22 streams indicate that K. moenkhausii is associated, on a mesohabitat scale, with runs, and on a microhabitat scale, with sandy bottoms, intermediate depth, and open sites without coverage or submerged vegetation. During snorkeling observations, two additional nektonic registered species showed spatial segregation from K. moenkhausii with respect to foraging microhabitats. Feeding habits of the observed nektonic species were significantly correlated with riparian vegetation. The six species studied appear to use different resources, as suggested by a non-metric ordination of diet, and sites with characteristic riparian vegetation. The studied species may be considered generalists with a tendency to insectivory, with K. moenkhausii feeding on the widest variety of resources. Such opportunism explains its ability to successfully occupy instream habitats with low complexity

“…But, further improvement of water quality, with increased water clarity, may be unfavourable to European pikeperch as this species prefers deep ( i.e. dark) or turbid waters (Poulet et al , 2005).…”

Fourteen non-indigenous fish species have been successfully introduced to the wild within the territory of Flanders; nine are considered naturalized. Most of the introductions occurred prior to 1950, with six species introduced since then. This paper reviews the available, hitherto scattered, information (including 'grey literature') on these 14 non-indigenous fish species introductions, and evaluates a decade of data from fisheries surveys to assess the recent development of these non-indigenous populations. Gibel carp Carassius gibelio and topmouth gudgeon Pseudorasbora parva are the most widespread of the non-indigenous species in Flemish waters, and both continue to expand their ranges. A reduction in range has been observed in brown bullhead Ameiurus nebulosus only. A case is presented for not including European catfish Silurus glanis, sunbleak Leucaspius delineatus and European bullhead Cottus gobio on the list of non-indigenous freshwater fishes in Flanders. Also discussed are non-indigenous fish species that are likely to colonize Flanders inland waters in the near future.
