Limestone Slurry Reduces Physiological Stress and Increases Survival of Atlantic Salmon ( Salmo salar ) in an Acidic Norwegian River
Smolts of Atlantic salmon (Salmo salar) were exposed for 70 h in the acidic River Vaaraana, southern Norway (Q = 1.3 m 3 /s, pH = 4.4–5.6, Ca = 0.6–1.5 mg/L, labile Al = 50–100 μg/L), to waters neutralized by addition of limestone slurry. Chemical and biological parameters were measured upstream of...
