Direct and indirect effects of riparian canopy on juvenile Atlantic salmon, Salmo salar, and brown trout, Salmo trutta, in south‐west Ireland
Abstract Dense riparian tree canopy is generally found to have a negative effect on salmonid populations. Canopy can affect fish both directly via trophic impacts and its effects as cover, and indirectly via its effects on the distribution of instream vegetation. This study examined the impact of ri...
