Density effect on growth rate of juvenile Atlantic salmon (Salmo salar) in manipulated large rivers
Growth rate of young-of-the-year (YOY) Atlantic salmon (Salmo salar) in low-density rivers was substantial better relative to YOY captured in normal density rivers. Mean growth index ± SD for YOY in low-density rivers was 1.10 ± 0.36 while the corresponding value in normal density rivers was 0.60 ±...
