Distribution and Abundance of Stream Fishes in Relation to Barriers: Implications for Monitoring Stream Recovery After Barrier Removal

Abstract: Dams are ubiquitous in coastal regions and have altered stream habitats and the distribution and abundance of stream fishes in those habitats by disrupting hydrology, temperature regime and habitat connectivity. Dam removal is a common restoration tool, but often the response of the fish assemblage is not monitored rigorously. Sedgeunkedunk Stream, a small tributary to the Penobscot River (Maine, USA), has been the focus of a restoration effort that includes the removal of two low-head dams. In this study, we … Show more

“…Gardner et al . () obtained similar results, and both studies attributed the peak in species richness to blockage of fish migration by dams. The rock‐ramp river did not show a distinct peak in mean species richness at the first site downstream of the rock ramp (Fig.…”

“…The and it was comparable for the small-bodied (average 0.31±0.04 g) fish. In our nutrientpoor system, fish biomass (27.5±3.7 g/m 3 ) was similar to the one measured in nature (Gardner et al, 2013) and thus may act as a nutrient subsidy (Ruegg, 2011). In contrast to our hypothesis, P and N inputs from fish were not high enough to overcome nutrient limitation.…”

“…Site‐specific and local impacts of dams have been extensively investigated (e.g. Gardner, Coghlan, Zydlewski, & Saunders, ; Greathouse, Pringle, Mcdowell, & Holmquist, ; Lessard & Hayes, ). However, small scale studies might prove insufficient for understanding ecosystem repercussions at a catchment scale (Campbell Grant, Lowe, & Fagan, ).…”
