Figure 2.

Growth, biomass and density of juvenile Atlantic salmon (Salmo salar) in streams with low (blue, n = 5) vs. high (green, n = 5) parental nutrient levels. Plotted are raw estimates for mean (± 1 SE) (a) fork length as a measure of growth, (b) biomass and (c) density for individual streams (unfilled circles) and the mean (filled circles; ± 1 SE) across streams within the low vs. high nutrient treatments. Fish density was estimated from depletion curves of the number of fish captured during triple‐pass electrofishing. Fish biomass was calculated as the product of the average fish body mass and the estimated density for each stream.
