Atlantic salmon were exposed to hydrogen peroxide (1.37–2.58 g l−1) over a range of temperatures (10.4–16.0 °C) simulating treatment for sea lice. Gill tissues and behaviour were monitored. Exposure to 2.58 g l−1 for 20 min caused total mortality (n = 18) while a shorter exposure, 10 min, at the same temperature caused only one mortality. Exposure to 1.37 g l−1 for 20 min at 10.4 °C caused no significant damage to gill tissues. There is a significant correlation (r = 0.895, F = 24.13, P < 0.01) between the level of exposure and the degree of gill damage.
