Density, size-at-age, and distribution of young Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in deep river pools



Density, size-at-age, and distribution of young Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in deep river pools



Canadian Journal of Fisheries and Aquatic Sciences. December; 5412: 2827-2836



A comparison of populations of juvenile Atlantic salmon (Salmo salar) and brown trout (Salmo trutta) in four deep pools (maximum depths 2.0-4.0 m) and 12 shallow riffles in three rivers showed significantly higher density, size-at-age, and biomass of the pool-dwelling salmonids. There were 2.5 times more part per unit of area in the pools compared with the riffles (95.3 and 37.5 parr/100 m2, respectively, p = 0.0053).
